I have climate data in big
netCDF file which covers 60 years time span climate data observation (please take a look into this link). However, I want to subset this climate data for only recent 20 years while discarding the time period that I don't want to use. I used
raster package to read
netCDF file in R, but to get a smaller chunk of raster grid from original
netCDF file is unknown to me.
I want to subset or get a smaller chunk of raster grid (only 20 years' period climate data observation) from big
netCDF file (it covers 60 year's climate data).
Is there any efficient fast way to get this done in R?
