A new sea surface temperature (SST) dataset from the WindSat radiometer on the Coriolis satellite in now available from the JPL PO.DAAC. This radiometer senses in the microwave spectrum and is thus relatively immune to clouds similar to the now defunct AMSR-E instrument on the NASA Aqua platform. The spatial resolution is 0.25 degrees with a twice daily temporal resolution. In the data processing chain, a near-real-time (NRT) dataset (identified with a "rt" within the file name) is made as available as soon as possible. A subsequent final dataset (identified by "v7" within the file name) is produced later and contains more observations than the NRT version. These data are produced by Remote Sensing Systems in support of the Group for High Resolution Sea Surface Temperature (GHRSST) Project. Although it is called "L2P Gridded" it is actually Level 3 (a grid).


UAVSAR completed its Hawaii deployment on January 14 where we successfully conducted 5 local flights acquiring data over Kilauea volcano region. The latest data will be compared with data previously acquired in January 2010 and May 2011 to study the surface deformation caused by the March 2011 fissure eruption in Kilauea's east rift zone. A NASA news release of the deployment can be found here:
