Abstract:
- This data publication consists of measurements of smoke plume rise, emissions, and dispersion in and around eight wildfires in the western United States and prescribed fires in California, Idaho, and North Carolina. Eleven wildland fires were investigated between August 2009 and August 2011, allowing the research team to measure plume rise and smoke transport over a wide range of meteorological conditions, fire activity, fuels, and terrain. This data publication provides observations for the evaluation of smoke dispersion and air quality forecasting models. The data publication includes measurements of prognostic variables (plume height and the concentrations of aerosol, carbon dioxide, carbon monoxide, and methane) of plume rise models, smoke dispersion models, and atmospheric chemistry transport models. The subcomponent models of smoke modeling systems, such as plume rise and fire effects models rely on a variety of fire environment data as input including ambient meteorological conditions, fuel type, fuel loading, and fuel condition. In addition to measuring model prognostic variables, this data publication also has ancillary data consisting of fire environment variables which are input for the subcomponent models of smoke modeling systems.
-
Purpose:
- Air quality regulators, land managers, and atmospheric scientists all rely on smoke emission and atmospheric chemistry modeling systems to predict, evaluate, and manage the impact of fire emissions on air quality and atmospheric composition. There is an urgent need to quantitatively characterize the uncertainties, biases, and application limits of smoke modeling systems and to develop improved systems for air regulators, land managers, and air quality forecasters. Accurately describing and predicting the dynamics of smoke plumes and subsequent smoke transport is a major uncertainty in determining the impact of fire emissions on air quality. This dataset provides measurements for the evaluation and development of smoke modeling systems.
-

Attribute_Accuracy_Report:
- These data include data collected from an airborne platform, data collected from a ground-based mobile Lidar, estimates of pre-fire fuel loading, and a multi-polygon shapefile that provides fire perimeters.
Airborne Platform: Data collected from the airborne platform and included in this dataset are 1. location, 2. volume mixing ratio of carbon dioxide (CO2) , carbon monoxide (CO), methane (CH4), and water vapor (H2O), 3. light scattering, and 4. plume height.
1. The aircraft location was provided by a GARMIN global positioning system (GPS) receiver with a reported accuracy of +/- 15 meters (m) on average (GARMIN: About GPS, available at: https://www8.garmin.com/aboutGPS/, last access: 16 July 2013).
2. The Legacy Aircraft Package (LAP) employed a non-dispersive infrared instrument to measure volume mixing ratios of CO2 and H2O. The uncertainty of the LAP measured CO2 is as estimated +/-5% (based on the analytical uncertainty of the calibration standards) and the accuracy of the H2O measurement is unknown. A cavity ring-down spectroscopy (CRDS) gas analyzer was used to measure mixing ratios of CO2, CO, CH4, water vapor. The estimated analytical uncertainty of the CRDS measurements is +/-1% to +/-1.5% for CO2 and CH4 and+/-2% (at 3 parts per million by volume, ppmv) to +/-15% (at 0.100 ppmv) for CO (see data document section 2.2 of Urbanski et al. [2013]). The average CRDS measurement precision, defined as the 14 s standard deviation while measuring a calibration standard is CO2 = 0.293 ppmv, CH4 = 0.005 ppmv, CO = 0.027 ppmv. The accuracy of the CRDS water vapor measurement is unknown. The analytical uncertainty and measurement precision vary with flight and the data document (see section 2.2 of Urbanski et al. [2013]) should be consulted for flight specific uncertainty estimates.
3. The study employed a Radiance Research M903 Integrating Nephelometer to measure light scattering (bscat) at a wavelength of 530 nanometers (nm). The measurement precision varies with bscat and is estimated as +/-7% for bscat > 50 1/Mm (megameters) and data accquisition rate of 0.5 Hertz. (see section 2.2 of Urbanski et al. [2013]). The accuracy of the bscat measurement is unknown. The measured bscat can be used to infer the mass density of aerosol of fresh smoke by applying a biomass burning mass calibration factor (see section 2.2 of Urbanski et al. [2013]) and uncertainties associated with this calibration are provided in the data document.
4. The average uncertainty in the measured smoke plume height is estimated as +/-30 m.
Ground-based Lidar: The ground-based Lidar measured plume height minimum and maximum with an estimated uncertainty of +/- 30 m.
Fire perimeters: The fire perimeter polygons were created by incident management teams and were acquired from official web sites for interagency wildland fire incident data or directly from personnel involved in fire incident management activities. The accuracy of the fire perimeters is unknown. Uncertainties associated with using these data are discussed in section 2.2 of Urbanski et al. (2013).
Fuel loading: Pre-fire fuel loading was estimated by combining fire perimeters polygons, a USFS forest type group map (Ruefenach et al. [2008]), and a forest fuel loading model (Keane et al. [2013]). The average bias of the fuel load is -3.5% for duff, -2.4% for litter, +0.9% for fine woody debris, and -0.1% for coarse woody debris (Keane et al. [2013]). The overall classification accuracy for the forest type group map is 65% (Ruefenach et al. [2008]).
-
Logical_Consistency_Report:
- Frequent in-flight calibrations were used to maintain accuracy of the trace gas measurements and quantify the measurement precision. The CRDS analyzer was calibrated in-flight using three-point calibrations. In the laboratory, a five point calibration was conducted to verify linearity of CRDS response to CO between 0.030 ppmv and 10 ppmv. The non-dispersive infrared instrument was calibrated in-flight using a two-point calibration. All procedures are detailed in supporting documentation (Urbanski et al. [2013]).
-
Completeness_Report:
- Measurements of CO and CH4 are not available for the fires measured in 2009 and 2010. Non-dispersive infrared instrument data is not available for the fires measured in 2011.
Airborne meteorological data is only available for prescribed fires measured in California and North Carolina.

Methodology_Description:
- PRIMARY DATA:
Three classes of primary data are contained in this data publication: measurements of smoke plume height, smoke emissions, and the spatial distribution of aerosol and trace gases released by wildland fires.
Observations of plume height were obtained through the deployment of a ground based, mobile Lidar and atmospheric chemistry instrumentation deployed on an aircraft platform. In this project, Lidar measurements of light backscattering were processed with a specially developed analysis methodology, the Atmospheric Heterogeneity Height Indicatory, to provide estimates of plume height. In addition to Lidar observations, the aircraft platform provided measurements of plume height by obtaining vertical profiles and transects of smoke concentrations (aerosol and carbon monoxide [CO]) as well as ocular estimates based on GPS elevation when the aircraft was level with the top of the smoke plume/smoke layer.
Using an aircraft platform, measurements of smoke aerosol (PM2.5), CO2, CO, and CH4 concentrations were obtained in fresh smoke and in the background atmosphere upwind of the fires. These measurements can be used to determine emission factors (EF) for the measured species and the modified combustion efficiency (MCE), which can be used to estimate EF for a wide range of reactive gases emitted by fires.
An aircraft platform was used to measure the spatial distribution of aerosol, CO, and CH4 concentrations downwind from wildland fires using vertical profile and horizontal profile transect sampling modes. These concentration fields measured from 0 to 50 kilometers (km) downwind of the fire provide the observations needed to evaluate the concentration fields simulated by smoke dispersion and atmosphere chemistry transport models (ACTM). Additionally, the vertical concentration profiles at the source may be used to initialize the vertical emission profiles used to initialize smoke dispersion/ATCM simulations.
Airborne Sampling Approach:
The airborne smoke sampling acquired measurements of fresh emissions, smoke vertical profile, plume height, and smoke dispersion (the spatial distribution of emissions downwind of the fire). These measurement objectives were accomplished using three flight sampling modes: 1) fresh smoke samples near the fire, 2) vertical profiling at distances of up to 50 km downwind of the source and 3) horizontal transects at distances of up to 50 km downwind from the source.
Sampling Mode 1: Fresh smoke on the edge of the plume column was sampled at multiple elevations.
Sampling Mode 2: Vertical profiles may be obtained either with spiral or step increase profiles. Spiral vertical profiles, centered on the plume downwind from the source are taken from above the smoke plume/smoke layer to the lowest practical elevation. The lowest elevation of sampling was dictated by the Project Aviation Safety Plan which established a minimum flight altitude of 500 (150 meters [m]) to 1,000 feet (ft) (300 m) above the terrain depending on conditions. Step increase vertical profiles involve short (~10 km) horizontal transects, roughly perpendicular to the long-axis of the smoke plume (i.e. perpendicular the direction of smoke transport), taken at multiple elevations. Because step increase profiles are time consuming and may miss some vertical structure of the smoke plume, nearly all of the vertical profiles were acquired using the spiral flight mode. The spiral sampling profile is ideal for measuring the vertical distribution of smoke concentration downwind of a fire if the smoke is homogeneously distributed in the horizontal plane across the diameter of the flight path. This is not always the case.
Sampling Mode 3: The third sampling mode traverses the plume horizontally, roughly perpendicular to the direction of smoke transport, at multiple locations downwind of the source. The horizontal transects were usually executed at the approximate level of maximum smoke density. During some flights, horizontal transects were obtained at multiple vertical levels.
Lidar Measurement Technique in the Vicinity of Large Fires:
The mobile Lidar measures the elastically backscattered light signals as a function of range (or height) at two wavelengths simultaneously, in the infrared (1064 nanometer [nm]) and the ultraviolet (355 nm) regions of the spectra. The backscattered signals at 1064 nm are used for monitoring smoke plume dynamics and propagation. The signals at 355 nm are used for calculation of smoke particle optical properties. The range of the Lidar is up to 5-10 km, depending on atmospheric conditions. The range resolution may be set from 6 to 30 m. The scanning capabilities of the Lidar allow it to change the searching direction rapidly through 180 degrees horizontally and 90 degrees vertically.
Objectively identifying smoke plume dimensions was achieved using an improved methodology developed for analyzing Lidar vertical scans obtained in areas of smoke plumes. The new methodology identifies heterogeneity events each of which is a fixed case of increased atmospheric heterogeneity in a local segment in the two-dimensional space searched by a scanning Lidar (Kovalev et al. [2009]). Heterogeneity events from a fixed azimuthal scan are used to create the Atmospheric Heterogeneity Height Indicator (AHHI) a histogram which shows the number of heterogeneity events in the consecutive height intervals (Kovalev et al. [2009]). From the AHHI, the smoke-plume maximum height is the maximum height where the plume presence can be discriminated from noise in Lidar data.
AIRBORNE INSTRUMENTATION:
The primary platform for the airborne measurements was the USDA Forest Service Region 1 (USFS R1) Cessna 206 aircraft. The project deployed the USFS R1 Cessna to wildfire events during August 2009, 2010, and 2011. The Cessna 206 was installed with atmospheric chemistry instrumentation. Measurements for two prescribed fires included in this report were obtained as part of a separate research project (Department of Defense Strategic Environmental Research and Development Program (SERDP) projects RC-1648 and RC-1649) that used the USDA Forest Service Region 4 Twin Otter aircraft as the sampling platform. Details of the SERDP projects may be found in Yokelson et al. (2013).
Legacy smoke sampling aircraft package (LAP)
The LAP integrated two sampling systems a nephelometer and a non-dispersive infrared CO2/H2O analyzer, into a single aircraft deployable unit. The LAP included a Garmin global positioning system (GPS), which provided time stamped aircraft locations (latitude, longitude, elevation above mean sea-level) at 1 Hertz (Hz). The nephelometer was a Radiance Research Model 903 integrating nephelometer that measured light scattering at 530 nm every 2 seconds. The nephelometer was installed with a 2.5 micrometer cut-off cyclone in the sampling line to limit the measurements to PM2.5 (a cyclone with 2.5 micrometer cut-point passes only particles with an aerodynamic diameter of less than 2.5 micrometer, i.e. PM2.5). Nephelometer measurements of light scattering by particles can be related to particle mass concentration through a mass calibration (see section 2.2 of the dataset document). The LAP measured trace gases using a non-dispersive infrared instrument (LI-COR gas analyzer model LI-6262) which provided measurements of CO2 and H2O vapor at a rate of 0.5 Hz. In-flight two-point calibrations were used to maintain CO2 measurement accuracy and determine measurement precision.
Cavity Ring-down Spectroscopy (CRDS) trace gas analyzer
A flight ready CRDS trace gas analyzer (Picarro Inc., CA, USA, model G2401-m) for the continuous measurement of CO2, CO, CH4, and H2O was deployed along with the nephelometer and GPS unit from the LAP. The G2401-m analyzer used in this study scans lasers over the individual spectral lines of CO2, CO, CH4, and H2O at wavelengths between 1560 nm and 1650 nm to measure the concentrations of these gases. The analyzer tightly controls the gas sample temperature and pressure at +/- 0.005 C and +/- 0.0002 atm to provide stable, well-resolved spectral features and ensure high precision measurements. The data acquisition rate was 2 s. The CRDS also logged a Garmin global positioning system (GPS), which provided time stamped aircraft locations (latitude, longitude, elevation above mean sea-level) at 1Hz. Frequent in-flight three-point calibrations were used to maintain measurement accuracy and determine measurement precision.
ANCILLARY DATA:
Fire Perimeters: The fire perimeter polygons, which were obtained from multiple sources, were put into a common projection and combined into a single shapefile.
Fuel loading
The surface fuel load for the area burned was estimated from a geospatial overlay of the incident fire perimeters with a US Forest Service map of forest type group (Ruefenacht et al. [2008]). The forest type group map was combined with a forest type fuel classification from a recent study by Keane et al. (2013). The fuel classification of Keane et al. (2013) includes fuel loading for six fuel bed components: litter, duff, and 1-hr, 10-hr, 100-hr, and 1000-hr dead wood for 19 forest type groups. Keane et al. (2013) did not include canopy fuels and herb and shrub fuels. For this project, the forest type fuel loadings were augmented with estimates of herbaceous and shrub fuel loadings of 0.05 kg/m2 and 0.08 kg/m2, respectively for all forest types (see Section 2.2 of the data document for details (Urbanski et al. [2013]). The canopy fuel loading, which is the canopy fuels likely to be consumed in a fully active crown fire (needles, lichen, moss, and live and dead branch wood less than 6 mm in diameter), was estimated using the canopy geospatial layers canopy cover, canopy height, canopy base height, and canopy bulk density from the LANDFIRE project (LANDFIRE [2012]), see Section 2.2 of the data document for details (Urbanski et al. [2013]).

Source_Contribution:
- Surface weather observations from the interagency Remote Automatic Weather Stations (RAWS) are located throughout the US (URL at time of publication: http://raws.fam.nwcg.gov/) and we have cited the RAWS closest to each of our study’s fires in the fire event summaries. RAWS data may be accessed through the Real-time Observation Monitor and Analysis Network (ROMANS). RAWS provide hourly observations of temperature, dew point temperature, relative humidity, wind speed, wind gust speed, wind direction, precipitation, solar radiation, and 10-hour fuel moisture.
