Soliciting Public Comments Through November 30, 2010
for Experimental
Gridded Localized Aviation Model
Output Statistics Program (LAMP) Products
Effective Tuesday, September 28, 2010, the NWS began producing experimental Gridded LAMP observations and guidance products for the CONUS and disseminating them on the NWS server. These products are available in GRIB2 format. The NWS is seeking user feedback on these products through
November 30, 2010.
The Gridded LAMP products contain guidance on a 2.5 km Lambert
Conformal grid covering the same expanse as the National Digital
Forecast Database (NDFD) CONUS grid. Grids will be generated
hourly consisting of gridded forecasts for projections of
1 to 25 hours in advance, as well as gridded observations for
the initial time of the Gridded LAMP cycle. Grids will initially
be available for the following elements with others to be added
at a later date:
2-meter temperature observations and the associated error
estimations
2-meter dewpoint temperature observations and the associated
error estimations
Ceiling height observations
Visibility observations
2-meter temperature forecast guidance
2-meter dewpoint temperature forecast guidance
Ceiling height forecast guidance
Visibility forecast guidance
The products are available in GRIB2 format in the National
Digital Guidance Database (NDGD). They will initially be
available on the NWS server at:
ftp://tgftp.nws.noaa.gov/SL.us008001/ST.expr/DF.gr2/DC.ndgd/GT.lmpgfs/AR.conus
or
http://weather.noaa.gov/pub/SL.us008001/ST.expr/DF.gr2/DC.ndgd/GT.lmpgfs/AR.conus
A web page outlining the Gridded LAMP products and the NWS server
directory and file structure can be found online at:

brief survey and comment form available on line at:
