The Historical Arctic Rawinsonde Archive

The Historical Arctic Rawinsonde Archive (HARA) contains over 1.2 million rawinsonde ascents, vertical soundings of temperature, pressure, moisture and wind from fixdc-position (mostly land) stations north of 65 degrees North latitude. For some stations, particularly North America, the record begins as early as 1948. The data base is archived in ASCII files on cdrom.

The database was assembled from five original archives obtained from the National Center for Atmospheric Research in Boulder, Colorado, and the National Climatic Data Center in Asheville, North Carolina. The archive contains sounding data for 95 individual stations (see figure below), including 50 stations in the Russian Arctic. Records of at least 5 yr in length are available for 80 stations; records of at least 10 yr are available for 69 stations.

Access Information

The HARA is being distributed by the National Snow and Ice Data Center in Boulder, Colorado. Information on how to obtain the data set is available here.

Locations of routinely-reporting, fixed-position stations contained in the Historical Arctic Rawinsonde Archive. This archive is an extensive collection (over one million soundings) of Arctic upper-air meteorological data during the period 1948-1987). Symbols denote the number of years (NYR) for which data are available.
