View source: R/RCGLS-functions.R

Read single layers of Copernicus Global Land Service (CGLS) data and adjusts coordinates for R.

1	ncvar_get_CGSL(date, product, resolution, version, variable)

`date`	Date of interest, for example for 13 june 2019: 2019-06-13
`product`	Product name: fapar, fcover, lai, ndvi, ss, swi, lst, ...
`resolution`	1km, 300m or 100m
`version`	Version number: v1, v2, v3,...
`variable`	FAPAR_ERR, FAPAR_QFLAG... Also see https://land.copernicus.eu/global/products/

Adjusting coordinates is a necessary step to use the data because Copernicus nc files have lat/long belonging to the centre of the pixel, and R uses upper/left corner. This function opens the data without any corrections.

CGLS data Large matrix of a specific variable in environment, coordinates adjusted.
