Subject:  Amended: HYSPLIT Trajectories Request Function to be
          provided via Weather Forecast Office NWS Spot Forecast
          Request Webpages Effective September 19 2011

Amended to extend the comment request period through December 31,
2012, to allow a HYSPLIT education/outreach effort and more
meaningful user evaluation.

NWS is accepting comments until December 31, 2012, regarding the
Hybrid Single Particle Lagrangian Integrated Trajectory model
HYSPLIT) Trajectories Request Function when provided via WFO NWS
Spot forecast request webpages. Comments concerning this experimental
service are welcome:

  http://www.weather.gov/survey/nws-survey.php?code=NSWHT

Effective September 19, 2011, all WFO NWS Spot forecast request
webpages will host a new, experimental functionality for requesting
HYSPLIT trajectory runs from NOAAs Air Resources Laboratory (ARL).
These elements will be available based on the North American
Mesoscale Model(NAM) for CONUS and the Global Forecast System (GFS)
for Alaska and Hawaii.

The HYSPLIT Trajectories Request Function allows partners and users
to request HYSPLIT trajectory runs at 500, 1500, and 3000 meters
above ground level for the latitude/longitude of the spot forecast
request location.  The trajectory runs will begin at the request time
for wildfires and emergency responses, and at the specified ignition
time for prescribed fires.

To request HYSPLIT trajectories from WFO NWS Spot forecast request
webpages, the authorized user must enter the phrase "hysplit to
email@xxxxxxxxxx" in the remarks section of the spot forecast request
form. The HYSPLIT trajectory raw data, as well as ".gif" and ".kml"
files, will be sent to the specified email address.

Site-specific (spot) forecasts are issued by WFOs in support
of official requests for wildfire management, natural resource
management, emergency response and other threats to public safety.
NWS Spot forecast requests are made via any of several of the
normal methods (e.g., from Regional/WFO Fire Weather pages,
telephone/facsimile, etc.)
