Description:
Abstract:
The data in this publication include relative humidity, air temperature, vapor pressure deficit, leaf temperature, and photosynthetic photon flux density, collected at multiple canopy heights at the Sabana Field Research station in the Luquillo Experimental Forest located in Puerto Rico. Light sensors (photosynthetically active radiation) as well as air and leaf temperature sensors installed on a canopy access tower were collected approximately six weeks during the summer of 2017 and are provided as 30-minute averages. These data, collected as a part of the Tropical Response to Altered Climate Experiment (TRACE), were focused on the exploration of vertical microclimatic gradients that occur along the tropical canopy structure.
Purpose:
These data were collected to explore the microclimatic change that occurs in a tropical wet forest canopy.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Height values were estimates using the canopy tower's known platform heights. The temperature and humidity values were the direct output of the instruments using their calibration methods and internal quality control. The light measurements were also direct instrument outputs. These outputs were put into half hour averages post-collection.
Completeness_Report:
If a value equals 'NA', no data were collected for that time at that height.

Methodology_Type: Field
Methodology_Description:
The micrometeorology data were collected from a walk-up aluminum tower at the Sabana Field Research Station that is approximately 20 meters (m) tall. This tower was installed as part of the Tropical Responses to Altered Climate (TRACE) experiment, and was already present at the site at the beginning of this study. Data were collected with solar shielded air temperature and humidity sensors (HOBO, Onset Corp, Bourne MA) paired with infrared temperature sensors and a datalogger (SI-100, Apogee Instruments, Logan UT and CR800, Campbell Scientific, Logan UT) aimed at clusters of leaves adjacent to the tower at a distance of approximately 45 centimeters from each sensor. Six pairs of sensors were placed at heights of 2, 6, 9, 12, 16, and 20 m. Some of the sensors had to be placed at heights within half a meter of their partner sensors to account for leaf locations, but height values were rounded to the nearest meter. Photosynthetic photon flux density (PPFD) was measured at the top (20 m) and middle (10 m) of the tower with photosynthetically active radiation (PAR) sensors and dataloggers (HOBO S-LIA-M003 and HOBO Microstation H21, Onset Corp, Bourne MA). All meteorological data were sampled every two minutes and averaged over a half-hourly period. Vapor pressure deficit (VPD) was calculated using the method described in Murray (1967). Air temperature and humidity sensors recorded data from May 19th to July 6th, 2017 except for the 12-meter sensor which recorded from May 19th to June 5th, 2017. Leaf temperature sensors recorded from May 18th to July 6th, 2017. PPFD was collected at 10 m from May 19th to June 5th, 2017 and at 20 m the data were collected from May 18th to July 6th 2017.
