Project Description
Arctic climate changes are increasingly recognized as being reflective of global trends. Yet, cumulative change can only be demonstrated by maintaining long records of indicators, such as temperature, ice extent, surface albedo, and temperature, that have measurable responses which can be compared over time. The value of the Historic Arctic Rawinsonde Archive derives from these two premises. Containing millions of vertical soundings of temperature, pressure, humidity, and wind, the archive represents a sensitive chronicle of tropospheric events and patterns occurring over the past four decades.

7. Detailed Description
The Historic Arctic Rawinsonde Archive (HARA) is designed to facilitate climate analyses requiring sounding time series at multiple stations throughout the Arctic. The archive contains millions of vertical soundings of temperature, pressure, humidity, and wind, and represents all available rawinsonde ascents from Arctic land stations poleward of 65 degrees North, from the beginning of record through mid-1996. For most stations, the record begins in 1958. A few begin in 1947 or 1948.
Data are stored as one file per year, per station. Please review the Historic Arctic Rawinsonde Archive data set documentation for complete information. Data is distributed on CD-ROMs.
