AMSR-E stopped rotating on Oct 4th, 2011. This affects the AMSR-E, TMI_AMSR-E MW OI SSTs and the MWIR SST products from day 275 onward.
We are hoping to release a new version of OI SST products soon which will contain WindSat SSTs. Look here for more information. Until that time, the Version-3 MW OI products stop at julian day 275, 2011, except for TMI MW OI SSTs.
New TMI, TMI_AMSRE and AMSRE OI SST files are available. Look for file dates after March 2010.
All MWIR OI SST products are currently being reproduced to Version-3. This process will take up to a year to complete. Contact support if you need older version files.
New read routines in IDL, Matlab and Fortran are available and format details are provided in the Data Description web page.
AMSR-E, TMI, and TMI_AMSR-E MW-only OI SSTs have been reprocessed to Version-3.

Microwave (MW) + InfraRed (IR) OI Sea Surface Temperature (SST)
Product: |
Foundation SST (~12 UTC) |
Resolution: |
~.09 Degree (~9 kilometer) Gridded (4096 x 2048) |
Derived from: |

Time Coverage: |
Global (90N to 90S): |
2006-Apr-10 through ~NRT |
|
Comments: |
IR allows higher spatial resolution, and SST near land.
However, IR input is less accurate than MW due to cloud contamination. Blending MW and IR enables greater coverage and higher accuracy than IR only SSTs, but current OI does not completely eliminate cloud contamination inherent to IR SSTs.
For climatological accuracy, consider MW OI SSTs. |
Data file format is detailed in the MW OI SST Description.
Read routines are available at ftp.discover-earth.org/sst/daily/read_routines.
