DMSP SSM/I Daily and Monthly Polar Gridded Sea Ice ConcentrationsDMSP SSM/I Daily and Monthly Polar Gridded Sea Ice Concentrations in polar stereographic projection currently include Defense Meteorological Satellite Program (DMSP) -F8, -F11, and -F13 daily and monthly sea ice concentrations. Using the Bootstrap algorithm, data gridded at a resolution of 25 x 25 km, begin 25 June 1987. Processing is ongoing. The Special Sensor Microwave Imager (SSM/I) derived ice concentrations are daily total and monthly averaged ice fractions for both hemispheres. The data are provided in Hierarchical Data Format (HDF), with accompanying Graphical Interchange Format (GIF) browse files and are available via FTP.Note: Users interested in sea ice concentration using the NASA Team algorithm are advised to use Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I Passive Microwave Data.
