LAMP Information and Documentation
Information For Upcoming LAMP/GLMP v2.2.0 Upgrade. Estimated effective date: October 2019
An upgrade to the LAMP and Gridded LAMP systems is planned to be implemented in NWS Operations October 2019. This section deals with documentation relative to the this upgrade (v2.2.0).
- Presentations: Slide package for User Evaluation (3/10/2019, pptx format, size ~ 14.3 MB).
- LAMP/GLMP v2.2.0 User Evaluation Form (feedback period open until April 1, 2019)
- Implementation Notification - Service Change Notice 19-61: Changes to LAMP station-based and gridded guidance effective October 22, 2019
- Experimental LAMP and GLMP graphics and products: GLMP and LAMP experimental web page.
- The current LAMP and GLMP product locations on the NWS server are unchanged with this implementation. For more details about the locations of these products on the NWS server, please see the links under "Products on NWS server" below.
- The current LAMP and GLMP WMO headers are unchanged with this implementation. For more details about the WMO headers for these products, please see the links under "WMO Headers" below.
- The new GLMP ceiling and visibility headers from projections 26-38 h (Coming Soon!).
- Presentations: Science Briefing to NCEP (Coming Soon!).
- Additional Stations: With this implementation making the following station changes:
- Adding LAMP guidance for San Bernadino, CA (KSBD). There will now be LAMP guidance of ceiling height, visibility, obstruction to vision, sky cover, precipitation type, conditional ceiling, and conditional visibility for KSBD.
- Changing the station identifer for Heber City, UT from K36U to KHCR.
- In January 2018 we added 332 stations to the LAMP ceiling, visibility, and obstruction to vision guidance. With this implementation, we are adding LAMP sky cover, precipitation type, conditional ceiling, and conditional visibility to those 332 stations, where possible. This new guidance will be added to the text bulletins and the BUFR files.
