Local Energy-budget Measurement (LEM) Weather Station Data. Version 1.0

This data is from the University of Utah's LEMS instruments captured September - November 2012 and April - June 2013 during the Mountain Terrain Atmospheric Modeling and Observations (MATERHORN-X) field campaign. LEMS are solar powered, low-cost Energy-budget Measurement Stations, which have been designed and assembled at the University of Utah EFD lab. LEMS monitor incoming solar radiation (LI-200), 2-m air temperature and relative humidity (Sensirion SHT 15, Humidity +/- 2-5% Temperature +/- 0.5K), air pressure (Bosch BMP085), surface temperature (Zytemp TN9), as well as soil temperature and moisture (Decagon 5TM) at two levels below ground. Data are logged using an Arduino-based open source controller with a data logger that can store up to 2 GB of data. These are the original raw data files and have not undergone quality control procedures. These files are in ASCII CSV format with a header line. Data filenames contain the specific instrument ID. The time stamps are based off of UTC time for all the instruments for the MATERHORN-X data, unless it was stated otherwise. Please see the README file for more information.
