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 the NGM MOS guidance itself. This system was implemented at the National Weather Service (NWS) Weather Forecast Offices (WFO) in the late 1990's.

LAMP has now been redeveloped to update the more modern GFS MOS guidance. The current status is that LAMP updates GFS MOS on an hourly basis, is run on National Centers for Environmental Prediction (NCEP) computers and disseminated centrally from NCEP, and provides guidance for over 1500 stations as well as thunderstorm guidance on a 20-km grid out to 25 hours.

The operational guidance from this 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 every hour at NCEP. Guidance is available from the following cycles: 0000, 0100, 0200, 0300, 0400, 0500, 0600, 0700, 0800, 0900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2100, 2200 and 2300 UTC (LAMP now runs for each hour of the day) For more details about the new system, please visit our LAMP Information page or read the latest AMS preprint detailing an Overview of LAMP.
