The development of radiosonde systems in the former Soviet Union (FSU) over the past 70 years is described, and the extent and organization of the aerological network is discussed. The quality and compatibility of data from FSU radiosondes are compared with those from the most widespread foreign radiosondes. Plans for changes in FSU radiosonde systems are outlined.

Abstract

The boundary layer structure measured by 402 pairs of approximately collocated radiosonde and dropsonde temperature profiles over the Arctic Ocean during the period 1957–61 is examined. The radiosonde profiles were obtained at the Russian drifting ice camps “North Pole 7” and “North Pole 8,” and the dropsonde profiles were measured during the United States Air Force “Ptarmigan” series of weather reconnaissance flights. The boundary layer structure is characterized by the features of the low-level tropospheric temperature inversion.

The results indicate that the dropsonde soundings, although containing relatively few measurement levels, contain sufficient vertical resolution to characterize the temperature inversion. Systematic differences were noted in wintertime inversion features and near-surface temperatures as measured by dropsondes and radiosondes. These differences are attributed to contrasting temperature lag errors accompanying ascending and descending sensors.

An historical archive of over 25 000 radiosonde observations from the former Soviet “North Pole” series of drifting ice stations has been compiled and made available to interested researchers. This archive is the only long-term set of meteorological sounding data over the Arctic Ocean. The digital archive is a result of the multiyear, collaborative efforts of a group of United States and Russian scientists and keypunch operators working under the auspices of Working Group VIII, an area of study within the United States–Russian Federation Agreement for Protection of the Environment and Natural Resources. The archive contains soundings from 21 drifting stations over the period 1954–90 and is being distributed by the National Snow and Ice Data Center in Boulder, Colorado.
