                <gco:CharacterString>The L3_FT_P_E product provides daily estimates of binary freeze-thaw state, retrieved from backscatter measurements acquired by the SMAP radiometer, using a seasonal change-detection algorithm. Data from both AM (descending) and PM (ascending) radiometer coverage are gridded at 9km resolution on a boreal polar grid at 9 km resolution. AM/PM transition flags indicate changes in freeze-thaw state between morning and evening observations.</gco:CharacterString>

The instruments share a rotating reflector antenna with a 6 meter aperture that scans over a 1000 km swath.  The bus is a 3 axis stabilized spacecraft that provides momentum compensation for the rotating antenna.</gco:CharacterString>

                                <gco:CharacterString>Freeze-thaw binary state is retrieved from radiometer brightness temperature data on both descending (AM, fore/aft) 
                                and ascending (PM, fore-only) SMAP half-orbits.  The L3_FT_P_E product includes only data northward of 45N latitude.
                                Freeze-thaw state retrieval is inhibited for areas with permanent snow/ice and excessive static or transient open water in the cell, 
                                and when there is excessive RFI in the sensor data. Retrievals may be flagged as questionable for urban areas, 
                                mountainous areas with high elevation variability, and for cells in which the seasonal (thawed-frozen) reference 
                                difference is much smaller than the radiometer measurement error.</gco:CharacterString>
