The data are reprojected and interpolated from their original polar stereographic projection at 10km spatial resolution to the 4km Pathfinder Version 5.2 grid. When the OSISAF data are not available for both hemispheres on a given day, the sea ice concentration data are taken from the sea_ice_fraction variable found in the L4 GHRSST DailyOI SST product from NOAA/NCDC, and are interpolated from the 25km DailyOI grid to the 4km Pathfinder Version 5.2 grid.

attribute	l2p_flags	comment	String	Bit zero (0) is always set to zero to indicate infrared data. Bit one (1) is set to zero for any pixel over water (ocean, lakes and rivers). Land pixels were determined by rasterizing the Global Self-consistent Hierarchical High-resolution Shoreline (GSHHS) Database from the NOAA National Geophysical Data Center. Any 4 km Pathfinder pixel whose area is 50% or more covered by land has bit one (1) set to 1. Bit two (2) is set to 1 when the sea_ice_fraction is 0.15 or greater. Bits three (3) and four (4) indicate lake and river pixels, respectively, and were determined by rasterizing the US World Wildlife Fund's Global Lakes and Wetlands Database. Any 4 km Pathfinder pixel whose area is 50% or more covered by lake has bit three (3) set to 1. Any 4 km Pathfinder pixel whose area is 50% or more covered by river has bit four (4) set to 1.
