2	Purpose of the GLFE Determine if the TAMDAR sensor can deliver reliable and accurate meteorological data when flying on a commercial airline fleet. Determine whether TAMDAR can help NWS meteorologists in field offices produce warnings and forecasts with greater precision and accuracy. Evaluate the effect of TAMDAR data when included in the Rapid Update Cycle (RUC) numerical weather prediction model.
3	Determine if the TAMDAR sensor can deliver reliable and accurate meteorological data when flying on a commercial airline fleet. AirDat will have a 24 hour a day engineering center in Evergreen, Colorado. They will monitor data from each aircraft and arrange for repair or replacement of faulty sensors. The Forecast Systems Laboratory in Boulder, Colorado will quality control the data further before it is included in the RUC model National Weather Service meteorologists in field offices will compare TAMDAR to other upper air data sources (radiosondes, wind profilers, WSR-88D VAD wind profiles, etc), and report discrepancies to AirDat via a message board.
4	Determine whether TAMDAR can help NWS meteorologists in field offices produce warnings and forecasts with greater precision and accuracy. NWS meteorologists will use TAMDAR in forecasts and warning in the following program areas Severe Convective Storms Assessing Stability Monitoring capping inversions Determine potential for rotating storms Aviation Forecasts Detect low level wind shear Locate moist layers and inversions for cloud and fog forecasting Winter Weather Determine freezing level and locations of temperature inversions to forecast precipitation type of winter storms Fire Weather Soundings will be used in narrative, point and spot forecasts - Marine Weather . Determine winds and stability upstream of lakes and oceans for wind and wave forecasts
5	Evaluate the effect of TAMDAR data when included in the Rapid Update Cycle (RUC) numerical weather prediction model. TAMDAR will be used as input in retrospective runs of the RUC model and compared to model runs without TAMDAR data Skill scores will be computed to determine if TAMDAR increases the accuracy of model output TAMDAR may be included in real time RUC output later in the GLFE if FSL resources permit
6	Purpose of the GLFE If TAMDAR proves to be a reliable, accurate source of upper air data, AirDat plans to proceed with a larger scale implementation of TAMDAR with other airlines and airfreight companies
