| attribute | NC_GLOBAL | summary | String | This ERDDAP data set provides the latitude - longitude grid for the Arctic (Northern Hemisphere) NSIDC passive microwave sea ice concentration climate data record (CDR) datasets distributed via the PolarWatch ERDDAP. The grid used for these datasets is the NSIDC polar stereographic grid with 25 x 25 km grid cells. The input netCDF files from NSIDC contain data variables and reference latitude and longitude variables. These are provided in this ERDDAP as separate datasets based on system architecture requirements. |
