AIRDAT HISTORY
© 2013 . Proprietary and Confidential
• The TAMDAR goal:• Deliver all metrics of weather balloons from commercial aircraft
• Assure space-time data coverage for airports sector
• GPS stamp all data
• Add additional electronic pilot reports (icing, turbulence, temp)
• Initial focus on regional aircraft to provide better geographic coverage
• AirDat was founded in 2003
• First STC and operational weather data in 2004
• Assets purchased by Panasonic Avionics Corporation in 2013
Tropospheric Airborne Meteorological Data Reporting
• Delivers a unique real-time high resolution data stream for improved atmospheric analysis and weather forecasting
• Patented and operational on commercial aircraft since 2004
• Goal: Deployment of TAMDAR and development of superior atmospheric information tools driven by the TAMDAR dataset
• Panasonic Avionics Corporation is expanding the TAMDAR network worldwide

Note: Over 100 daily soundings fromLGA, JFK, EWR
The 2 images show TAMDAR data from flights into/out of BUF +/- ~3h from 10 pm.
The solid triangles indicate icing, and the hollow triangles indicate icing with heaters activated.
The TAMDAR heater remains activated throughout the descent, so the ice accretion rate is > 0.02” / min.

TAMDAR observations around the time of the Colgan crash
The first sounding, valid 9 pm, shows a substantial layer of saturated air below 6000' between -9 and -2C -- the temperature window that most supports the existence of supercooled water.
The second sounding, valid 11:20 pm, shows the sub-0C saturated layer has dropped to 3000' and belowBoth soundings suggest favorable conditions for supercooled water to freeze upon airframe contact.

Raytheon, AirDat, and Metron Aviation have teamed to support two major FAA NextGen weather programs with superior weather information, integrated displays, and decision support solutions: • NextGen Network Enabled Weather (NNEW)
• NextGen Weather Processor (NWP)
WHY TAMDAR?
Validated by NOAA via 4-year FAA-funded TAMDAR impact study*
• Temperature 3-hour forecast errors are reduced by up to 28%.
• Wind forecast 3-hour errors are reduced by up to 10%.
• Relative humidity 3-hour forecast errors are reduced by up to 50%.

Improvements in forecast skill:TAMDAR over without-TAMDAR,(RAOBs used as "truth“)
NOAA's most optimized model for aircraft data is RUC
AirDat 3D-Var WRF is essentially the same code as NCAR 3D-Var WRF
AirDat RT-FDDA and 4D-Var WRF are best suited to utilize asynoptic observations
