Where:
GWXCW is
W2019203 is W year and day of year: WYYYYdoy
C15 indicates number of granules in composite (generally 14 or 15)
Series of 6 digit numbers are start times each granule included in the composite
NP06 (or SP06) indicates mapped to Polar Stereographic Projection for North Pole (NP06) or South Pole (SP06) 
Ice Conc is product name = Ice Concentration
.nc is NetCDF format (CF compliant)
