As of February 2022, the LAMP pages hosted on the weather.gov server will be transitioning to the NOAA Virtual Lab (home page: https://vlab.noaa.gov/web/mdl/lamp). Please discontinue use of the LAMP weather.gov pages and instead use the LAMP VLab pages. All links to live data still go to the nws.noaa.gov server, so any bookmarks you have to live data should be unaffected by this change, which only impacts the static, informational LAMP webpages.

Please see here for more information about this transition.

Note:  While we are transitioning our web pages, all of the products below link to product pages on the old system. Products on those pages are up-to-date, but links on those pages may go to old information or may be broken. Thank you for your patience!

Gridded LAMP (GLMP) is a program which provides gridded analyses of observations and operational LAMP forecasts for aviation forecasting. The output grid aligns with the CONUS NDFD grid (#227) at 2.5km. The jobs run hourly in the NWS job stream. Gridded forecast guidance and gridded observations are currently available for the following elements:

  • 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
  • Opaque sky cover observations
  • 10-meter wind speed observations
  • 10-meter wind direction observations
  • Opaque sky cover forecast guidance
  • 10-meter wind speed forecast guidance
  • 10-meter wind direction forecast guidance
