Total Ozone and Reflectivity from NIMBUS-7 TOMS (HDTOMS)Entry ID: OZ_BN-3
Abstract: This TOMS ozone data set consists of the following product:
HDTOMS -- High Density Tape from TOMS (Level II, NSSDC ID: 78-098A-09C)
The High Density Total Ozone Mapping Spectrometer (HDTOMS) dataset from Nimbus 7 HDTOMS provide global earth coverage from 90 deg N to 90 deg S with a resolution of 50 km x 50 km at nadir and 250 km x 250 km at scan extremes. For the first 7-1/2 months, data ... are nominally available 10 out of 12 days. Beginning June 22, 1979, TOMS had been operating full time until May 7, 1993 when the sensor stopped taking measurements.
The HDTOMS contains scan by scan (35 samples each) and orbit by orbit the following: 1) total ozone values (in Dobson units), 2) effective Lambertian surface reflectivities, and 3) calibrated albedos measured at six wavelengths from 312.5 to 380 nm. Reflectivities are determined from measurements made by the two longest wavelength bands, and total ozone values are determined from the four shorter wavelength bands. There are approximately 18 tapes per year.
The gridded TOMS datasets are derived from HDTOMS and are now available through the EOSDIS DAAC at NASA/Goddard Space Flight Center (GSFC DAAC). For more information see the GSFC DAAC at: http://disc.gsfc.nasa.gov/
