Total Column Ozone & Ozone Profile From Atmospheric Explorer BUV Mission

Overview

The Backscatter UV Spectrometer (BUV) (a spare from the Nimbus 7 program), was flown on the Atmospheric Explorer (AE-E) satellite (also known as AE-5 and Explorer 55) on November 20, 1975, to measure the solar UV radiation reflected and scattered by the earth's atmosphere. The AE-E satellite also carried other UV sensors to study in detail the upper atmosphere. AE-Ehad provided data far beyond its nominal life expectancy. It re-entered the atmosphere on June 10 of 1981. More details can be found in A. Dalgarno et al., Radio Sci., v. 8, n. 4, p. 263, 1973.

The mission summaries are given in:
"Atmosphere Explorer project; AE-E mission operation report," NASA, No. S-852-75-05, Nov. 1975. and " Atmosphere Explorer-E (Explorer 55) post launch report #1" NASA, No. S-852-75-05, Dec. 1975.

The Instrument

TheBackscatter UV Spectrometer (BUV) instrument comprising of a tandem Ebert-Fastie double monochromator and an interference filter photometer channel, measured the UV radiation reflected back from earth to space at 12 wavelengths from 2550 Å to 3400 Å. From these measurements the ozone mixing ratios at six atmospheric pressure levels from 0.4 mbar to 30 mbar were deduced.Dr. Donald F. Heath has been the principal investigator for the BUV missions.

The details of the BUV instrument, measurements and results are described by Spencer et al. (1973), Kreuger et al. (1976), Guenther et al.(1977), Frederick et al.(1977, 1981), and Blitza et al.(1995).

Data Products & Formats

Parameters:

  • Total columnozone
  • Ozone mixing ratios (at 6 pressure levels: 0.4, 1, 2, 5, 10, and 30 mbar)

 Data Format: 

Each data file contains one day of data (ASCII format). The first record is the header. It is followed by the block of data records for each specific parameter. The files are named as Eyymm_dd.DAT (for example: file E7512_01.DAT contains data for Dec 01, 1975)


Data Availability & Access

Available Data Period: December 1970 - June 1981

Data is free and available on-line. It can be downloaded from the FTP site.
