THIRN7L1NCLE is the Nimbus-7 Temperature-Humidity Infrared Radiometer (THIR) Level 1 Cloud Data in ERB Format (NCLE) product and was generated from the THIR 11.5-micrometer radiances, the TOMS derived UV (0.36 and 0.38 micrometer) reflectivities, and the Air Force surface temperature. Data consist of total cloud amounts in percent coverage; cloud amounts at three altitudes: low (below 2 km), middle (2 to 7 km depending on latitude), and high (above the middle cloud layer); percent cirrus and deep convective cloudiness; and surface radiances. Data are averaged orbit by orbit to the Nimbus 7 Earth Radiation Budget (ERB) experiment subtarget areas (STA), approximately 165 km x 165 km each. The NCLE product is a new version of CLE, with improved cloud estimation.
Each file contains one day of data (~14 orbits per day). Spatial coverage is global. The data are available from April 1, 1979 (day of year 91) through March 31, 1985 (day of year 90).
This product was previously available from the NSSDC with the identifier ESAD-00054 (old ID 78-098A-10D)
