4.22 - Daily Maximum Temperature File (*.tmx)

The daily maximum temperature file (*.tmx) contains maximum daily temperature values in degrees Fahrenheit for each climate station for years t1nyr1 through t1nyr2, described below. The daily maximum temperature 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 maximum temperature file. An example is provided in Appendix A. Note that daily climate data can not be processed with a monthly consumptive use method (e.g. Modified Blaney-Criddle, Original Blaney-Criddle, or Pochop).
