4.8 - Monthly Precipitation File (*.prc)
The StateCU monthly precipitation file contains total monthly precipitation values in inches for each
precipitation station for years
gnyr2, described below. The monthly precipitation file
is used for the monthly Blaney-Criddle ET methods (
= 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. The file
must contain data (or -999) for all years in the simulation between
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 the climate station data included in the monthly precipitation
file. An example is provided in Appendix A.
|Row 1||Format (6x, i4, 11x, i4, 7x, a3)|
|1-1||gnyr1||Beginning year of precipitation data|
|1-2||gnyr2||Ending year of precipitation data|
|1-3||idum3||CYR for calendar year|
|Row 2||Format (i4, 1x, a12, 12(f8.2))|
|2-2||tid||Precipitation station ID|
|2-3||tmpt (1, tyr, 1-12)||Total precipitation for months 1-12 (inches)|
Repeat for the number of precipitation stations.
Repeat for each year
