MUR Replaces G1SST Blended Sea Surface Temperatures
MUR Replaces G1SST Blended Sea Surface TemperaturesPosted October 17, 2017
Voyager and Voyager Mobile now offer Multi-scale Ultra-high Resolution (MUR) sea surface temperatures (v4.1). These global, near real-time, satellite-derived data sets are available at daily and monthly time spans at approximately 1-km (0.01°) resolution, extending from June 2002 up to the present. This replaces the daily Global 1-km Sea Surface Temperature (G1SST) product previously available in Voyager and can be found in Voyager’s overlay menu under the headings “remote sensing” > “satellite data” > “MUR (SST)”. The Group for High Resolution Sea Surface Temperature (GHRSST) stopped producing G1SST this past month and recommend switching to MUR.
Data are based on the night-time GHRSST L2P skin and sub-skin SST observations that are blended from several space-borne remote sensing instruments, including the NASA Advanced Microwave Scanning Radiometer-EOS (AMSR-E), the Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Aqua and Terra platforms, the U.S. Navy microwave WindSat radiometer, Advanced Very High Resolution Radiometer (AVHRR) on several NOAA satellites, as well as in situ SST observations from the NOAA iQuam project.
