This set of ozone data was supplied by the NASA Ozone Processing Team on 9-track, 1600-bpi tapes, in IBM binary format. The data set is a condensed version of the HDBUV (NSSDC ID 70-025A-05Q). Measured radiances, absorption coefficients, and instrument calibration for 13 wavelengths (0.25 to 0.34 micrometer) are contained in the header record. Data records contain earth-located total ozone (with and without IR cloud height information), reflectivity, ozone mixing ratios, and layer ozone amounts. The mixing ratios are given at 19 pressure levels (0.3, 0.4, 0.5, 0.7, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0, 7.0, 10, 15, 20, 30, 40, 50, 70, and 100 mbar). The layer ozone amounts are given for 12 layers: 0-0.24, 0.24-0.49, 0.49-0.99, 0.99-1.98, 1.98-3.96, 3.96-7.92, 7.92-15.8, 15.8-31.7, 31.7-63.3, 63.3-127, 127-253, and 253-1013 mbar. This data set was reprocessed using the same algorithm as that used to process the Nimbus 7 Solar Backscatter Ultraviolet (SBUV) data set (78-098A-09Q). Their formats are identical, but users should note that ground truth data had been used in adjusting the BUV albedos for changes in instrument sensitivity, thus rendering uncertainty in the derived ozone values for long-term trend study. Also, dark current counts that are zenith angle dependent and that affect the derivation of ozone profiles, especially at high altitudes, are flagged. For further information, refer to the "Note to Users of BUV Tapes," issued in 1987.
This data set was transferred to the Goddard DAAC in January 1995.
