Some further information on Pathfinder
There are L3, 4km AVHRR Pathfinder data available beyond 2009, but this is for v5.2 of the Pathfinder dataset that PO.DAAC currently does not distribute. The v5.2 data are, however, available via NOAA/NODC at ftp://ftp.nodc.noaa.gov/pub/data.nodc/p ... ersion5.2/
At PO.DAAC we currently have Pathfinder v5.0 and v5.1, although we may also get 5.2 in future. Please note that v5.2 has only Daily data; unlike some of the earlier Pathfinder versions, composited products are not available for v5.2. To our knowledge there are no plans for Pathfinder v5.2 composites to be produced near-term, but on the plus side this version is a GHRSST-compliant dataset. Also please note that Pathfinder version reprocessings that would make the series more current only occur occasionally. We are unaware when a future version release would occur. If you need more current SST data and a reasonably long time series, then you may want to consider MODIS-Terra & Aqua SST L3 datasets available from PO.DAAC (see http://podaac.jpl.nasa.gov/datasetlist? ... =MODIS:*3*
) which span 2000-present.
