Aquarius L3 Weekly Polar-Gridded Landscape Freeze/Thaw Data V005

This Level-3 (L3) data set includes weekly Northern Hemisphere landscape freeze/thaw (FT) data derived from L-band radiometer brightness temperature observations, acquired by the Aquarius sensor on board Argentina's Satélite de Aplicaciones Científicas (SAC-D) satellite. The data are distributed on the Equal-Area Scalable Earth Grid, Version 2.0 (EASE-Grid 2.0), with a spatial resolution of 36 km. The SAC-D satellite was developed collaboratively between NASA and Argentina's space agency, Comisión Nacional de Actividades Espaciales (CONAE).
