This experimenter-supplied set of gridded total ozone data was generated by an IBM 370/3081 computer onto magnetic tape. Derived from the TOMS ozone data tapes (HDTOMS; NSSDC ID 78-098A-09C), it consists of daily averages of total ozone, reflectivity, and time of observation on geographic grids. Total ozone values are determined from measurements made at four wavelengths (339.8, 331.2, 317.5, and 312.5 nm), and reflectivity is derived from two longer wavelengths (380 and 360 nm). Only good quality data from ascending orbits are selected, averaged, and binned into 1-deg latitude zones that cover from 90 deg S. to 90 deg N. Bands are further divided into grids that vary from 1.25 deg longitude at the equator to 5 deg at the poles. There is one tape per year. Version 5 TOMS was replaced in 1990 by Version 6 TOMS which applied a long-term correction to the data. See Herman, J.R., R.McPeters, and R.Stolarski, "Global Average Ozone Change from November 1978 to May 1990", J. Geophys. Res., Vol. 96, No. D9, pp. 17297-17305, Sept. 20, 1991.
This tape data set as well as data on CD-ROM in three volumes (see 78-098A-09Z, 78-098A-09a-c) have been transferred to the Goddard Distributed Active Archive in March 1994.
