The Airborne Antarctic Ozone Experiment (AAOE), Including Halley Bay Ozonesonde Data on CD-ROM

The DC-8 aircraft flew at the lowermost extremities of the hole and deployed a combination of remote sounding of the overlying atmosphere with some in situ sampling. Vertical distributions of ozone and aerosols above the cruising altitude of the aircraft and within the hole were mapped. The DC-8 collected ozone and aerosol profiles overhead by LIDAR; and measured ozone, bromine oxide, OClO, nitrogen dioxide, nitric acid, and hydrogen chloride.

In situ methods yielded ozone, total water, and whole air sampling. This CD-ROM also contains the results of the ozonesonde program at Halley Bay (76 degrees South, 27 degrees West) in 1987, where one file corresponds to one ozonesonde ascent. Instances of abnormal conditions affecting the data are noted.

All files within this release are standard ASCII files with variable length records. The file naming convention uses a two character prefix to identify the instrument followed by a six digit number giving the year, month, and day (GMT) of the flight (or balloon launch). A three character name as in ER2, DC8, or OZn is used to denote the data is from either the ER-2, DC-8, or ozonesonde (OZ1 for the first launch, OZ2 for the second launch on a particular day).
