Subject: Upgrade to High Resolution Real Time Global
Sea Surface Temperature Analysis:
Effective October 11, 2011
On Tuesday October 11, 2011, the National
Centers for Environmental Prediction (NCEP) will make several changes to the High Resolution Real Time Global Sea Surface
Temperature Analysis system (RTGSSTHR). These changes are expected to improve
performance of the RTG sea surface temperature (SST) analysis.
The analysis system changes include:
1. Add use of Remote Sensing Systems (RSS) retrievals of SST from Advanced Microwave Scanning
Radiometer (AMSR) to analysis system.
2. Switch from using NOAA-18 AVHRR SST for
retrievals to using NOAA-19.
The combined effect of these changes has resulted
in the following improvements to the analysis:
1. Reduced time between observation-based
updates of analysis in cloudy regions.
2. Improved bias and rms of the analysis with respect to buoy observations.
Data format, volume, and delivery will not
be affected by this implementation.
The RTGSSTHR products are available on the
NCEP Server at
http://www.ftp.ncep.noaa.gov/data/nccf/com/gfs/prod/sst.YYYYMMDD or
ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/sst.YYYYMMDD
where YYYYMMDD corresponds to the four
digit year, two digit month and two digit day.
The data is also available on NOAAPORT with
the WMO header ETWA88 KWBI.
The Environmental Modeling Center (EMC) has a publicly available website which
can provide users more information concerning the RTGSSTHR:

content of the RTGSSTHR please contact:
