THIR/Nimbus-7 Level 1 Cloud Data for SBUV/TOMS V001 (THIRN7L1BCLT) at GES DISC
Listed in NASA Data Portal
Description
THIRN7L1BCLT is the Nimbus-7 Temperature-Humidity Infrared Radiometer (THIR) Level 1 Cloud Data for SBUV/TOMS (BCLT) product and contains total cloud amounts; radiances at three cloud altitudes: low (below 2km), middle (2 to 7 km depending on latitude), and height (above the middle cloud layer); cirrus and deep convective clouds; and mean and RMS deviations of cloud and surface radiances. Data are averaged orbit by orbit onto each of the Nimbus 7 TOMS IFOV, which vary from 50 km to 50 km at nadir to 200 km x 200 km at the edges, as well as SBUV 180 km x 180 km IFOVs.
The BCLT product includes improved cloud estimation compared to the earlier CLT product. Each file contains one day of data (~14 orbits per day). Spatial coverage is global.
