ncvar_get_CGSL: Read netcdf CGLS data

Description

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

Usage

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

Arguments

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/

Value

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

Details

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.

Examples

# NOT RUN {
#' library(ncdf4)
DATE <- "2019-06-13" #Date of interest, for example for 13 june 2019: 2019-06-13
