The Multiscale Ultrahigh Resolution (MUR) Level 4 sea surface temperature
dataset has undergone a revision to version 4. This new version has an
updated parameterization for the high-latitudes based on sea ice
concentration data. It also uses the following new datasets: WindSat
microwave SST data and iQuam in situ SST data.
The new version is now available as of 1 March 2013. Historical MUR SST
(back to mid-2002) will be converted to version 4 over the next several
months. A few directories on the PO.DAAC FTP server may contain both versions
(3&4) for an interim period.
