The Backscatter Ultraviolet (BUV) experiment on board the Nimbus 4 polar orbiting satellite has been measuring the total ozone content and high-level atmospheric ozone profiles since early 1970. Synoptic type analyses of these data are now being accomplished and compared with appropriate constant-pressure analyses of stratospheric circulation. Ozone changes during a stratospheric warming of early 1971 are investigated by comparison with circulation changes in the layer between 30 mb (24 km) and 2 mb (42 km). A general increase in ozone concentrations, more pronounced in the higher latitudes, is noted during the warming period. Plans for future investigation are discussed, including analysis of ozone observations beginning from 1970 on every two-day basis for comparison with constant-pressure height, temperature, and wind charts analyzed with the aid of radiosonde, rocketsonde, and satellite data.
Results of two experiments involving intercomparisons of rocketsonde measurements of temperature and wind data in the 25 to 80 km altitude region in the CIMO (Commission for Instruments and Methods of Observations) program during September 1973 are reported. Rocketsonde systems used by France, the USSR, the UK, the U.S., and Japan in the two parts of the program (one series of tests at Wallops Island, Va., the other in French Guiana) are described. Wind data were derived from radar tracking of retardation devices and payloads in descent. Day and night temperature differences were examined. The intercomparisons revealed excellent compatibility of the rocketsonde data up to 60 km in wind observations. Some outstanding problems are pointed out.
Stratospheric temperature data obtained from instrumentation on board Nimbus 3 and 4 are compared with conventional rocket soundings to determine the compatibility of measurements. The Arcasonde 1A and Datasonde were the primary rocketsondes used, but acoustic grenade and pitot probe soundings were also involved. Observed temperature profiles and computed radiances obtained from rocket soundings are compared with 15-microns data provided by the satellite infrared spectrometers, the infrared interferometer spectrometer, and the selective chopper radiometer onboard the satellites. A reasonable agreement between the rocket and satellite data is indicated, but variations are noted which are related to the sounding techniques.
