In JGCRI/an2month: Monthly Downscaling of CMIP/ISIMIP tas and pr

Description

reindex_grid returns the fraction matrix to use in monthly_downscaling during the monthly downscaling process.

Usage

reindex_grid(frac, frac_coordinates, fld_coordinates, var)

Arguments

frac	the downscaling fraction list, internal pacakge data
frac_coordinates	the data frame of the fraction grid cell coordinates should be available from frac
fld_coordinates	the data frame of the field grid cell coordinates
var	the name of the variable to process, a string of tas or pr

Details

This function ensures that that the monthly fractions used in the downscaling and the data being downscaled have the same latitude and longitude coordinate system. This is important when working with ISIMIP and CMIP5 files since ISMIP has NA values that may be removed during an earlier step which would change the grid cell indexing of the data.

Value

the fraction matrix to use in monthly downscaling arranged so that the fraction grid cells match the order of the field grid cells
