Description:

Abstract:

The Prescribed Fire Combustion and Atmospheric Dynamics Research Experiment (RxCADRE) was designed to collect atmospheric, fuels, fire behavior, energy balance, emissions, and fire effects data to evaluate and advance fire models and further our understanding of fire science questions. This data package contains geometrically rectified and radiometrically calibrated raw long wave infrared (LWIR) images collected with the Wildfire Airborne Sensor Program (WASP) sensor at Eglin Air Force Base near Valparaiso, Florida in longleaf pine (Pinus palustrus) ecosystems of the southeastern USA as part of the RxCADRE project. The LWIR images quantify ground-leaving exitance released during five operational surface fires that burned in forested burn blocks in 2011 (608A and 703C), non-forested burn blocks (L1G and L2G), and a forested burn block in 2012 (L2F). Images are available every 4 seconds for the 2011 burns and every three seconds for the 2012 burns within each aircraft pass over a burn block.

Purpose:

The purpose was to acquire LWIR imagery to record the fire spread and radiative heat release at frequent intervals during prescribed fires. Pixel values are calibrated to Fire Radiative Flux Density (FRFD) in units of watts per square meter (Dickinson and Kremens 2015). Integrating the calibrated pixel values over the whole time series provides a measure of Fire Radiative Energy Density (FRED) in units of kiloJoules per square meter following Hudak et al. 2016.

Methodology_Description:

Long wave infrared (LWIR) images of the active fires were collected on 6 February 2011 at 703C, 8 February 2011 at 608A, 4 November 2012 at L1G, 10 November 2012 at L2G, and 11 November 2012 at L2F. The LWIR image frame collection interval within each overflight was 4 seconds for the two 2011 burns and 3 seconds for the three 2012 burns. The WASP sensor was mounted on a Cessna 206 fixed-wing aircraft owned and operated by Kucera International, Inc. Individual WASP image frames were orthorectified using GDAL (Geospatial Data Abstraction Library) software. Raw digital numbers (DNs) were calibrated to power flux density following Dickinson and Kremens 2015.

Process_Step:

Process_Description:

Orthorectified and calibrated WASP frames were converted from digital numbers to ground-leaving exitance (watts per square meter [W/m²]) using the following equations:

L_LWIR = f(DN) = 2 × 10^(-6) × DN^2 + (0.0176 × DN)

PT = pi × b ×(f(DN))^M

where DN is digital number, b and M vary by WASP acquisition, and PT is ground-leaving exitance (W/m²). For each acquisition, grids were resampled (nearest neighbor) to a common origin and resolution (based on the average resolution of the raw data frames).

See Dickinson and Kremens 2015 for more details.
