4.27 - Daily Wind Speed File (*.wnd)
The daily wind speed file (*.wnd) contains daily wind speed in miles per day for each climate station
for years wnyr1 through wnyr2, described below. The daily wind speed 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 wind speed file. An example is provided in Appendix A.
