Aquarius L3 Weekly Polar-Gridded Landscape Freeze/Thaw Data, Version 5 (AQ3_FT)
This is the most recent version of these data.
This data set is being updated to Version 5 to match the other Aquarius polar gridded data products.
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).

Data Access & Tools
Many NSIDC DAAC data sets can be accessed using the NSIDC DAAC's Data Access Tool. This tool provides the ability to search and filter data with spatial and temporal constraints using a map-based interface.
To convert HDF5 files into binary format you will need to use the h5dump utility, which is part of the HDF5 distribution available from the HDF Group. How you install HDF5 depends on your operating system.
