Land, Atmosphere Near real-time Capability for EOS
The product is similar to AIRS2SUP except the processing system that produced these radiances is a Near Real Time (NRT) system. This product this differs from AIRS2SUP.7.0 AIRSonly in four ways to meet the three hour latency requirement of the Land Atmosphere NRT Capability Earth Observing System (LANCE). For additional information about NRT processing see either the Related URL section or the References section for the NRT memo.
The quality of data products, described in the associated references, provide information about numerous validation studies conducted and papers written documenting the excellence of the products using radiosondes, ground truth, other satellites, and model analysis products.
Each variable contains a flag indicating the quality of the value. The three options for this quality flag are: 0 for best quality, 1 for good quality, 2 for do not use.

AIRS Near Real Time (NRT) data products
https://docserver.gesdisc.eosdis.nasa.gov/repository/Mission/AIRS/3.3_ScienceDataProductDocumentation/3.3.5_ProductQuality/nrt_memo_v6.pdf
The Atmospheric Infrared Sounder (AIRS) Level 2 Near Real Time (NRT) Support Retrieval (AIRS-only) product (AIRS2SUP_NRT_7.0) differs from the routine product (AIRS2SUP_7.0) in four ways to meet the three hour latency requirements of the Land Atmosphere NRT Capability Earth Observing System (LANCE): (1) The NRT granules are produced without previous or subsequent granules if those granules are not available within 5 minutes, (2) the predictive ephemeris/attitude data are used rather than the definitive ephemeris/attitude, (3) if the forecast surface pressure is unavailable, a surface climatology is used, and (4) no ice cloud properties retrievals are performed. The consequences of these differences are described in the AIRS Near Real Time (NRT) data products document. The Atmospheric Infrared Sounder (AIRS) is a grating spectrometer (R = 1200) aboard the second Earth Observing System (EOS) polar-orbiting platform, EOS Aqua. In combination with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB), AIRS constitutes an innovative atmospheric sounding group of visible, infrared, and microwave sensors. This product is product produced using AIRS IR only because the radiometric noise in several AMSU channels started to increase significantly (since June 2007). The Support Product includes higher vertical resolution profiles of the quantities found in the Standard Product, plus intermediate outputs (e.g., microwave-only retrieval), research products such as the abundance of trace gases, and detailed quality assessment information. The Support Product profiles contain 100 levels between 1100 and .016 mb; this higher resolution simplifies the generation of radiances using forward models, though the vertical information content is no greater than that in the Standard Product profiles. The intended users of the Support Product are researchers interested in generating forward radiance or in examining research products, and the AIRS algorithm development team. The Support Product is generated at all locations as Standard Products.
An AIRS granule has been set as 6 minutes of data, 30 footprints cross track by 45 scanlines. There are 240 granules per day, with an orbit repeat cycle of approximately 16 day.
The Near Real Time (NRT) product is for users whose primary interest is the low latency for data availability. While standard data products are available within 3 days of observation, NRT data are usually available within 3 hours of observation.
