MODIS/Aqua Temperature and Water Vapor Profiles 5-Min L2 Swath 5km - NRT

Metadata Updated: December 7, 2023

The level-2 MODIS Temperature and Water Vapor Profile Product MYD07_L2 consists of 30 gridded parameters related to atmospheric stability, atmospheric temperature and moisture profiles, total atmospheric water vapor, and total ozone. All of these parameters are produced for both daytime and nighttime conditions at 5-km pixel resolution when at least 9 FOVs are cloud free.

The atmospheric profiles are produced at 20 vertical atmospheric levels (5., 10., 20., 30., 50., 70., 100., 150., 200., 250., 300., 400., 500., 620., 700., 780., 850., 920., 950., 1000. mbar) The water vapor parameter is an estimate of the total tropospheric column water vapor made from integrated MODIS infrared retrievals of atmospheric moisture profiles in clear scenes. The thermal band 9.6 micron is used for retrieving total ozone burden.

The shortname for this Level-2 MODIS atmospheric profile product is MYD07_L2 and the principal investigator for this product is MODIS scientist Dr. Paul Menzel ( MYD07_L2 product contains data that has a spatial resolution (pixel size) of 5 x 5 kilometers (at nadir). Each MYD07_L2 product file covers a five-minute time interval, which means that the output grid is 270 5-km pixels in width and 406 5-km pixels in length for nine consecutive granules. Every tenth granule has an output grid size of 270 by 408 pixels.

MYD07_L2 product files are stored in Hierarchical Data Format(HDF-EOS). Twenty eight of the 30 gridded cloud parameters(5-kilometer pixel resolution) are stored as Scientific Data Sets (SDS) within the file, the remaining two algorithmic static parameters (band number and presure level) are stored as Vdata(table arrays). Cloud Mask SDS, derived from the 1-km MYD35_L2 Cloud Mask parameter, is remapped to 5-km resolution, by using only the center 1-km pixel in the 5x5 pixel retrieval array. The remaining two (band number and static pressure levels) are stored as Vdata(table arrays) Each file is roughly 8 MB in size, and the total data volume is approximately 2 GB/day.
