# 4.7 - Monthly Temperature File (*.tem)

The StateCU monthly temperature file contains average monthly temperature values in degrees Fahrenheit for each temperature station for years gnyr1 through gnyr2, described below. The monthly temperature file is used for the monthly Blaney-Criddle ET methods (flag1= 1 in the model control file, Section 4.4). Missing data is accepted using a –999 place holder. The data must be in calendar year format for the StateCU program. The file must contain data (or -999) 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 climate stations listed in the climate station data file (*.cli) and climate station data included in the monthly temperature file. An example is provided in Appendix A.

Row-Data Program Variable Description
Row 1 Format (6x, i4, 11x, i4, 7x, a3)
1-1 gnyr1 Beginning year of temperature data
1-2 gnyr2 Ending year of temperature data
1-3 idum3 CYR for calendar year
Row 2 Format (i4, 1x, a12, 12(f8.2))
2-1 tyr Year
2-2 tid Temperature station ID
2-3 tmpt(1,tyr,1-12) Average temperature for months 1-12 (Degrees Fahrenheit)

Repeat for the number of temperature stations.

Repeat for each year gnyr1 through gnyr2.
