###	Processing steps:

	1. Reproject to EPSG:3031
	gdalwarp -t_srs EPSG:3031 -r bilinear input.tif output.tif

	2. Mask out areas with no sea ice (thickness=0) and redefine NoData
	gdal_calc -A input.tif --outfile output.tif --calc="(A*(A!=0))+(A==0)*-9999" --NoDataValue=-9999 --co=COMPRESS=DEFLATE --co=BIGTIFF=YES

	3. Convert to Cloud-Optimised-Geotiff
	gdal_translate input.tif output.tif -of COG -r bilinear -co COMPRESS=DEFLATE -co BIGTIFF=YES
