4.25 - Daily Solar Radiation File (*.sol)
The daily solar radiation file (*.sol) contains daily solar radiation in langleys for each climate
station for years rnyr1 through rnyr2, described below. The daily solar radiation file is used for
the Penman-Monteith, Modified Hargreaves, and ASCE Standardized Penman-Monteith daily ET methods
(flag1= 3, 4, or 5, respectively in the model control file, Section 4.4). The data must be in calendar
year format. The file must contain data for all years in the simulation between nyr1 and nyr2, defined
in the model control file (see Section 4.4). There must be a one-to-one correspondence between the
climate stations listed in the climate station data file (*.cli) and the climate station data in the daily solar
radiation file. An example is provided in Appendix A.
