AIRS L2 Standard Product (AIRS/AMSU) NRT

Product Description Product Summary
AIRX2RET_NRT data sample product

The AIRS Level 2 Standard Retrieval NRT Product is produced by the same core science algorithms as in the regular science data production, but using predicted ephemeris in place of definitive ephemeris data and without using optinal dynamic inputs; AIRABRAD for previous and next 6 minutes and  NOAA Global Forecast data. The advantage of NRT data is its fast turnaround time, generally available within 3 hours of observations globally. The NRT data sets stay for about 7 days from the time they are generated.They can be utilized in regional weather forecast campaigns.

General information on AIRS L2 Standard Retrieval products is found in AIRX2RET.
