ORNL FACE Weather Data

Weather data are available for 1999-2007. There is an hourly (*wh*) and a daily (*wd*) file for each of the six plots (rings) on the FACE site, giving a total of 12 files for each year. The 2007 files will be updated as data become available. Daily statistics were calculated only for those variables with at least 12 good hourly values, and the calculation of daily statistics for the variables, PAR2m, PAR22m, and PYRAN, required 12 good daylight hours. Otherwise, the daily values were set to missing.
