    • MODIS/Aqua Raw Radiances in Counts 5-Min L1A Swath

    Metadata Updated: August 22, 2025

    The MODIS/Aqua Raw Radiances in Counts 5-Min L1A Swath product (MYD01) contains reformatted and packaged raw instrument data. MODIS instrument data, in packetized form, is reversibly transformed to a computer data structure, along with formatted engineering and spacecraft ancillary data. The Level-1A data is separated into granules for passage to the geolocation and calibration processes. Quality indicators are added to the data to indicate missing pixels and instrument modes. This product contains MODIS digitized raw detector counts data for all 36 MODIS spectral bands, at 250 m, 500 m, or 1 km spatial resolutions including all time tags, all detector views (Earth, solar diffuser, Spectro-Radiometeric Calibration Assembly (SRCA), black body, and space view), and all engineering and ancillary data. Quality indicators are added to the data to indicate missing or bad pixels and instrument modes. Only bands 20 to 36 are used to collect measurements in night mode, while all bands are used in day mode. Visible, short-wave infrared (SWIR), and near infrared (NIR) measurements are made during daytime only, while radiances for thermal infrared (TIR) are measured during both day and night portions of the orbit.
