The consequences of these differences are described in the AIRS Near Real Time (NRT) data products document. The AIRS VIS/NIR level 1B data set contains visible and near-infrared calibrated and geolocated radiances in W/m^2/micron/steradian for 4 channels in the 0.4 to 1.0 um region of the spectrum. The spectral range of the VIS/NIR channels are as follows: Channel 1 0.41 um - 0.44 um, Channel 2 0.58 um - 0.68 um, Channel 3 0.71 um - 0.92 um, Channel 4 0.49 um - 0.94 um. The AIRVBRAD_NRT_005 products are stored in files (often referred to as \"granules\") that contain 6 minutes of data, 90 footprints across track by 135 lines along track. The VIS/NIR granules are only produced in the daytime so there will always be fewer VIS/NIR granules than Infrared or microwave granules.", "distribution": [{"@type": "dcat:Distribution", "description": "AIRS Documentation Page", "downloadURL": "https://disc.gsfc.nasa.gov/information/documents?title=AIRS+Documentation", "format": "HTML", "mediaType": "text/html", "title": "View information related to this dataset"}, {"@type": "dcat:Distribution", "description": "AIRS home page at NASA/JPL.
