This repository conatains the following R files:

WBM-specific:

wbm_load.R

Functions: wbm_load()

• Uses the raster package to load WBM output files into R
• Reads multiple yearly WBM files into a single raster stack
• Only loads one variable

spatial_aggregation.R

Functions:

spatial_aggregation()

• Given gridded data and a polygon shapefile, aggregates grid values to polygons.
• Option: sum or average over polygons.
  • If sum is used, the function assumes the data is in mm and aggregates to km3 using either input grid area, or calculates grid area.

global.sum()

• Given gridded data, sums or averages all grids.
  • If sum, then input is assumed to be mm and output is in km3. Uses either input grid area, or calculates grid area.

global.sum.stack() NOTE: this function should be updated/merged with global.sum()

spatial.agg.ts()

linear_val.R

Functions:

linear_reg()

linear_val()

map_r2() *NOTE: need to make legend placement option, or at least place legend outside of map boundaries

General hydrology:

NSE.R

Functions: NSE()

Links to other data or models:

get_USGS_data.R

Functions: get_USGS_data()

FDC.R Functions: FDC()
