The first subdataset 'cdr_seaice_conc' is the one you want, but also included
are "cdr_seaice_conc_interp_spatial_flag", "cdr_seaice_conc_interp_temporal_flag",
"cdr_seaice_conc_qa_flag", "cdr_seaice_conc_stdev", "raw_bt_seaice_conc", "raw_nt_seaice_conc" and
"surface_type_mask"
Usage
seaice_cdr(date, hemisphere = c("south", "north"), vsi = TRUE)
Arguments
- date
date or or string YYYY-mm-dd
- hemisphere
north or south
- vsi
in GDAL url form

string with path to CDR sea ice netcdf file
Details
I've had mixed success setting subdataset and having these return with the correct orientation.
