NOAA's Earth System Research Laboratory Global Systems Division (formerly the Forecast Systems Laboratory -- FSL) is playing a central role in the distribution and evaluation of TAMDAR data. FSL's efforts include the following.
- Ingesting TAMDAR data from AirDat, LLC, performing additional quality control checks, and distributing the data to authorized users via our MADIS program.
- Providing documentation and consultation to NWS offices that have chosen to ingest TAMDAR data into their AWIPS workstations.
- Making the TAMDAR data available to authorized users on FSL's aircraft display at http://amdar.fsl.noaa.gov/java/
- Ingesting and displaying radiosonde soundings gathered by the University of Wisconsin CIMSS group for comparison with TAMDAR (and other aircraft) soundings.
- Evaluating the TAMDAR data on a case-study basis, such as by comparing TAMDAR soundings with nearby radiosondes and wind profilers.
- Generating and making publicly available on the web (http://amdar.noaa.gov/ruc_acars/) statistics (bias, rms error) for wind, temperature, and relative humidity for TAMDAR and other aircraft with respect to co-located 1h forecasts from various RUC models.
- Running in real-time parallel versions of the RUC model, one with TAMDAR (called "dev") and one without (called "dev2"). Plan view analyses and forecasts from these models are available (http://rapidrefresh.noaa.gov/), as are soundings (http://www-frd.fsl.noaa.gov/soundings/java/). The latter may be compared with actual aircraft soundings by users authorized to view the aircraft data.
- Hosting a NWS survey for operational weather forecasters on their use of TAMDAR data (http://amdar.noaa.gov/TAMDAR/survey/).
- Working with scientists at NCAR, we are comparing TAMDAR observations with written reports of turbulence, clouds, and icing generated by the pilots of the aircraft carrying the TAMDAR sensors.
This presentation will provide an overview of FSL efforts; several individual presentations in the special TAMDAR session will provide more details.
