• The Localized Aviation MOS Program (LAMP) system provides objective probabilistic and deterministic forecast guidance of sensible weather with a focus on guidance for aviation forecasting. The LAMP forecasts are available at stations in the United States (US). Gridded LAMP guidance for a number of forecast elements, including convection, lightning, ceiling height, and visibility, is also available on a 2.5-km grid covering the contiguous US.
  • IRIS is a web-based application to assist National Weather Service personnel in managing Impact-Based Decision Support Services (IDSS). IRIS integrates contact management, observation monitoring, impact management and alerting, and the generation of weather reports into a single application to assist NWS forecasters in providing effective IDSS to core partners. The IRIS system also supports the popular iNWS application that provides real time email and text message alerts to core partners for hazardous weather.
