Notification of Removal of NGM-LAMP
December 07, 2006
Updated: January 23, 2007
Attention LAMP users:
The LAMP system, which provides an update to the MOS guidance, is being redeveloped to update the GFS MOS guidance instead of updating the older NGM MOS guidance. The initial four cycles of the GFS-MOS based LAMP (GFS-LAMP) guidance became operational in July 2006. Beginning in 2007, the GFS-LAMP will provide operational guidance for as many (and eventually more) cycles as the NGM-MOS based LAMP (NGM-LAMP), and the NGM-LAMP will no longer be necessary.
Beginning with the OB8.1 release of AWIPS, we expect that there will be at least as many cycles of the GFS-LAMP guidance as the NGM-LAMP guidance. At that time, the NGM-LAMP system will be removed from AWIPS according to the approved OB8.1 content of the System Recommendation & Evaluation Committee (SREC). With the AWIPS OB8.1 release, the NGM-LAMP guidance will no longer be available, and the NGM-LAMP software will no longer run locally at CONUS WFOs in AWIPS. The product will be discontinued.
In response to the discontinuation of the NGM-LAMP in AWIPS, on or around November 1, 2007 the NGM-LAMP guidance will cease to be available on the NWS LAMP web site http://www.nws.noaa.gov/mdl/lamp/ngmlamp.shtml
Users are encouraged to prepare for the discontinuation of the NGM-LAMP well in advance of this time. The new GFS-LAMP guidance is currently available, and will continue to be available after the removal of the NGM-LAMP, and is intended to be used as a replacement for the NGM-LAMP. Information about the GFS-LAMP, including the real-time GFS-LAMP guidance, is available at the web site http://www.nws.noaa.gov/mdl/lamp/index.shtml.
For your reference, key differences between the NGM-based LAMP system and the GFS-based LAMP system are summarized below. Please note that the GFS LAMP does not currently provide guidance for either Quantitative Precipitation Forecasts (QPF) or Cloud Layer Amounts and Heights for 3 layers of clouds. It is possible that these elements may be developed in the future for GFS LAMP. The new GFS LAMP will provide guidance for categorical Ceiling Height and Total Sky Cover.
Key differences between the NGM-based LAMP forecast elements and the GFS-based LAMP forecast elements are summarized below:

Thank you for your interest in LAMP.
