tamdar造句

• The TAMDAR system has been in continuous operation since initial deployment in December 2004.
• Two parallel versions of the model were run with the control withholding the TAMDAR data.
• TAMDAR sensors continuously transmit atmospheric observations via a global satellite network in real-time as the aircraft climbs, cruises, and descends.
• TAMDAR observations are typically received, processed, quality controlled, and available for distribution or model assimilation in less than one minute from the sampling time.
• Likewise, the nature of the 30-day mean statistics dilutes the actual impact provided by TAMDAR's higher resolution data during critical weather events.
• Results from this study are summarized below using the same 30-day running mean verification statistics as employed by NOAA . TAMDAR impact using FDDA / 4D-Var resulted in:
• The TAMDAR sensor was originally deployed in December 2004 on a fleet of 63 FAAM aircraft . Recently, an installation agreement has been reached with a large Southeast Asian airline as well.
• TAMDAR data has been shown to increase forecast accuracy over the U . S . on the order of 30-to 50-percent for a monthly average, even for 3D-Var ( GSI ) models.
• Forecast skill, like the example presented above, is made possible by having ( i ) an asynoptic in-situ observing system like TAMDAR that streams continuous real-time observations to ( ii ) a forecast model ( deterministic or probabilistic ) that has the ability to assimilate asynoptic data in four dimensions.
• The FAA funded a four-year TAMDAR impact study that was concluded in January 2009 . The study was conducted by the Global Systems Division ( GSD ) of NOAA under an FAA contract to ascertain the potential benefits of including TAMDAR data to the 3D-Var Rapid Update Cycle ( RUC ) model, which was the current operational aviation-centric model run by National Centers for Environmental Prediction ( NCEP ).
