Localized Aviation MOS Program

LAMP is a statistical system which provides forecast guidance for sensible weather elements. The LAMP system was originally designed to update the NGM MOS by using the most recent surface observations, simple locally run model output, and and the NGM MOS guidance itself. This system was implemented at the National Weather Service (NWS) Weather Forecast Offices (WFO) in the late 1990's, and is still running there today.

LAMP is currently being redeveloped to update the more modern GFS MOS guidance. The operational guidance from that redeveloped system, in addition to technical information about the new system, can be found at this web site. This web site is not supported 24x7. However, please contact us if you notice that the data are old and we will try to rectify the situation as soon as we can.

The GFS-LAMP guidance is currently running operationally at NCEP. Guidance is available from the following cycles: 0000, 0100, 0300, 0400, 0500, 0600, 0700, 0900, 1000, 1100, 1200, 1300, 1500, 1600, 1700, 1800, 1900, 2100, 2200 and 2300 UTC (The next cycles planned are: 0200, 0800, 1400, and 2000 UTC, and will be effective 1st Quarter FY09).
