get_modscag_data: Function to get MODSCAG data.

In hoargroup/stationsweRegression: SWE Distribution for Station Observations

Function to get MODSCAG data.

Description

The function will check for existing processed fsca images in the imagepath. If it doesn't exist, it will check for raw, unprocessed files and mosaic them. If no file exist it will attempt to download them from snowserver and mosaic them.

Usage

get_modscag_data(doy, yr, type, imagepath, modscagfn = "snow_fraction",
  fveg_correction = TRUE, reso, xmin, xmax, ymin, ymax)

Arguments

doy	day of year
yr	year
type	'NRT' or 'historic'. near realtime download from snowdav or archived data
imagepath	the directory where the mosaiced fsca .tif files exist
modscagfn	'snow_fraction' or 'snow_fraction_canadj'; portion of the filename before the extension to identify canopy corrected or not corrected modscag;
fveg_correction	logical, default TRUE. should fsca be corrected by modscag fveg?
reso	resolution of fsca
xmin	minimum x coordinate of domain
xmax	maximum x coordinate of domain
ymin	minimum y coordinate of domain
ymax	maximum y coordinate of domain

Details

called for its side effect of producing a mosaicked fsca image of the domain

Value

rasterImage of fsca for the simulation date
