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:
