BASE Field Campaign
Model Initialization Data
The Beaufort and Arctic Storms Experiment (BASE) study was a Canadian-led international field campaign to study the weather systems occurring in southern Beaufort Sea and surrounding areas of the Arctic near the outlet of the MacKenzie River. A combination of two aircraft, two Dopler radars, enhanced rawinsonde and other surface weather observations made measurements from 1 September through 13 October 1994 to understand weather systems, their clouds and their impact on the regional climate of the MacKenzie River Basin. The experimental region extends approximately from 60N to 75N latitude and from 210E to 230E longitude. The BASE Project Homepage provides further information on BASE and the availability of data collected.
This case study presents data from 1 Sep 1994 to 13 Oct 1994 and covers a region from 60N to 75N latitude and from 150W to 130W longitude.
