The annual precipitation is used to calculate recharge from precipitation in the RRCA Groundwater Model. The program writes the annual precipitation in a format that can be directly appended to the annual precipitation file.
The mkppt program extracts total precipitation records from the TD3220 data set. These records are labeled TPCP and contain the monthly precipitation for each month (months 1-12) and annual precipitation (month 13). When an annual precipitation value is reported, the program selects that value. Otherwise, the program will sum the monthly values to obtain the annual precipitation.
The program extracts the precipitation records from the full data set for the following stations.

The program reads the TD3220 data from the file TD3220. This file contains final and provisional data. The provisional TD3220 data are derived from TD3200 daily data, and is to be used only for preliminary model runs. The final RRCA accounting runs should be run only with the final TD3220 data.
The program writes the annual precipitation to the screen. The output can be redirected to a file as needed. The output consists of one line of values per year, sorted in order of the station identifiers.
