| attribute | NC_GLOBAL | summary | String | This ERDDAP dataset provides the latitude - longitude grid for the Arctic (Northern Hemisphere) VIIRS sea ice datasets distributed via the PolarWatch ERDDAP. The coordinating projected grid is in NSIDC polar stereographic north projection (EPSG:3413). The input netCDF files from CoastWatch contain both the projected grid and the lat-lon grid and are available through the CoastWatch ERDDAP files access system. The lat-lon and projected grids are provided as separate datasets in ERDDAP due to ERDDAP's system architecture. |
