drop_NAs: Remove NA grid cells from processing in the emulator training...
In JGCRI/fldgen: Generate Temperature Fields with Spatial and Temporal Correlation

Description Usage Arguments Details Value

This function removes grid cells with missing data, NA values for all timesteps, from being processed by trainTP. This enables fldgen to work with output that has NAs in it.

1	drop_NAs(griddata)

griddata

output from concatGrids.general

The parts of the griddata structure that are affected are:

vardata: Missing grid cells are removed
globalop: Entries corresponding to missing grid cells are removed.

The following items are added, only if there were missing grid cells to drop.

ncol_full: Number of columns in the original matrix, before missing values were dropped.
gridid_full: Column ids in the original matrix, for the grid cells that were not dropped.
coord: Matrix of latitude and longitude for each grid cell. This is distinct from the lat and lon entries, which gives the latitude coordinate extracted from the original netCDF file.
