The Meteorological Development Lab has been working to transition the LAMP gridding techniques applied in the CONUS to Alaska. The work has involved adopting the LAMP/HRRR Meld CONUS techniques to blend information from the Global Forecast System based MOS (GFS-MOS), recent station observations, and the High Resolution Rapid Refresh (HRRR) model forecasts. This work adds value over current services by both improving skill of station LAMP ceiling height and visibility guidance while also making the guidance in a gridded form. Numerous adaptations were made to the gridded analysis of point data and the inclusion of gridded data into the overall gridded product. These adaptations included using Rapid Refresh (RAP) model data instead of HRRR model data and additional emphasis on the RAP model information over station-oriented data like observations or GFS-MOS in regions where there are few or no stations. This presentation will highlight the adaptations made in transitioning the LAMP CONUS ceiling height and visibility techniques to Alaska.
