[Ncep.list.nos-nowcoast-status] NOAA/NOS nowCOAST Status Message - SST Composite Analysis

Tue Aug 1 19:24:32 UTC 2023

3:22 PM EDT Tuesday, August 1, 2023

Since a few nowCOAST users had questions following the earlier Status
Message, please find a slightly revised announcement below.

Late yesterday afternoon,  nowCOAST Version 6.1.0 was released to the
public and is available at  *nowcoast.noaa.gov <http://nowcoast.noaa.gov>.*
The new version includes the return of the NASA Short-term Prediction
Research and Transition Center (SPoRT) experimental North American Sea
Surface Temperature (SST) Composite Analysis.  The analysis also provides
lake surface water temperatures for the Great Lakes and large inland lakes
such as Sebago Lake in Maine and Great Salt Lake in Utah.

*nowCOAST Service Changes:*

   - Added time-enabled Web Map Service (OGC protocol) for the NASA SPoRT
   experimental North American Sea Surface Temperature (SST) Composite Analysis

   Information about the map service can be found at
   https://nowcoast.noaa.gov/geoserver/analysis/sea_surface_temperature/ows?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities

Background Information about the SST Composite:
The NASA SPoRT Surface Temperature (SST) Composite is a blend of the
following data and analyses: 1) NASA high-resolution Moderate Resolution
Imaging Spectroradiometer (MODIS), 2) Visible Infrared Imaging Radiometer
Suite (VIIRS), 3) the NOAA/NESDIS daily global blended GOES/POES Sea
Surface Temperature Analysis, and 4) the United Kingdom Met Office daily
global Operational Sea Surface Temperature and Ice Analysis (OSTIA).
However, for inland lakes the GOES/POES SST analysis is not available. The
SPoRT compositing algorithm uses the most recent seven-day collection of
MODIS and VIIRS data and the most recent daily NESDIS GOES/POES SST
Analysis and OSTIA. The data and analyses are weighted according to data
latency and spatial resolution. The composite is calculated on a Northern
Hemisphere 2-km (1.1 nautical miles) grid up to 80 degrees N. The composite
is generated twice daily and valid for the periods 0000-1159 UTC and
1200-2359 UTC. The nowCOAST viewer displays the composites for the previous
four days.

*nowCOAST Map Viewer (nowcoast.noaa.gov <http://nowcoast.noaa.gov>)
Changes:*

   - Alphabetized Layers list in the map viewer menu
   - Users can now select menu titles to expand layer options
   - Added the SST service to the menu in additional layers

The nowCOAST map viewer allows users to pan and zoom on the SST composite
map and to obtain the SST in both degrees F and degrees C by selecting a
location with a click or touch.  An example of obtaining the SST off Cape
Hatteras is shown below.

The SPoRT SST composite has been available on nowCOAST for many years, but
unfortunately it was not available on nowCOAST @ AWS when the redirect from
NWS/NCO IDP Data Centers to AWS occurred on  April 19th. The SST composite
is available once again on nowCOAST.
