Description: Estimate monthly precipitation from NCDC data
Shell scripts used: mk_monthly_ir.scr Argument files: None
Source code: mk_monthly.c
Source code language: C
Compiler used: gcc –o
Additional information from the C code:
This program reads the output file from the regridding program (adjprcp_grid.grd). It then generates monthly values for jan,feb,mar,etc that will be used together with PRISM data to scale the timeseries in each gridcell
Input files: adjprcp_grid.grd
Output file: mk_monthly/*.monthly
Shell scripts used: run.mk_monthly.scr Argument files: None
Additional information from the additional script run.mk_monthly.scr: This script is used to run 'mk_monthly'.

Input files: 'mk_monthly/*
Output file: mk_mnth/monthly.*
Description: estimate monthly PRISM data
Shell scripts used: get_prism_ir.scr Argument files: None
Source code: get_prism.c
Source code language: C
Compiler used: gcc –o
Additional information from the script:
This program reads the prism data (C.Daly et al 1993) and converts them into monthly gridded data at a chosen resolution. The program needs a maskfile as input together with the prism rawdata. The rawdata used in this program is located at /can-usa-prism/can_us_prism.jan . These files contains prism data for USA. If other prism rawdatafiles are used, then lines 28 to 38 should be changed in this program. If there are gridcells forexample in Canada that the prism data is not covering. The no_data value will be written in the outputfiles corresponding gridcell . The rescaling program will check for this void value at a later stage and the precip value will not be scaled for this gridcell.
Input files: mask_125.asc, prism-rawdata/can_us_prism.*
Output file: Prism/prisim.*
Description: Rescaling the precipitation data

This program takes the yearly u-wind and v-wind NCEP/NCAR reanalysis data and regrids it from the t62-gaussian grid to a grid corresponding to the input mask file. The required inputs are those listed in the "run_regrid_wind.scr" file, and the files "gauss_t62_lat.list" and "gauss_t62_lon.list" must reside in the same directory as this file. These two files have the global lat/long coordinates of the reanalysis data. The output is one wind timeseries file for each grid cell active in the mask. This program also dumps two other files as output:
- wind_latlong.txt which is a list of file names for output
- cell_avg.out which is an average for each of 365 days for each cell These two files are used in the fill_data.c program, used to fill the wind data files with average daily wind speeds for each cell, for the years of VIC data preceding the reanalysis data.
