These data statistics are stored locally on EVE and also transmitted to a base computer system for archival, analysis and display. The Flux-PAM data-processing computer, known as EVE, ingests data from the sensors at rates commensurate with their individual response characteristics and calculates 5-min means, variances and covariances. To provide maximum siting flexibility, Flux-PAM stations are powered by solar-charged batteries and the sensor are mounted on an internally-guyed mast with a tripod base. These stations measure the standard meteorological variables of wind, temperature, humidity, pressure and precipitation plus net radiation, soil heat flux and the eddy fluxes of momentum, water vapor and sensible heat. 2.0 NCAR Flux-PAM Stationsįlux-PAM remote meteorological stations are one of the principal components of the NCAR Integrated Surface Flux Facility (ISFF). The Atmospheric Surface Flux Group instrumented a 20 m micrometeorological tower located about 1 km from the Des Groseilliers and also requested the use of four NCAR Flux-PAM stations to measure fluxes over a variety of different surface types. Army Cold Regions Research and Engineering Laboratory), Chris Fairall (NOAA Environmental Technology Laboratory), Peter Guest (Naval Postgraduate School), and Ola Persson (NOAA Environmental Technology Laboratory and the Cooperative Institute for Research in Environmental Sciences). The principal investigators in this group are Ed Andreas (U.S. The research teams at the ice camp included the SHEBA Atmospheric Surface Flux Group (ASFG), which was responsible for direct measurement of the fluxes contributing to the surface energy balance. During this period, Ice Station SHEBA drifted from approximately 75° N, 144° W to 80° N, 166° W. Des Groseilliers, which was frozen into the Arctic ice pack north of Alaska from October 1997 to October 1998. The field phase involved the deployment of numerous measurement systems on board and in the vicinity of the Canadian ice breaker N.G.C.C. SHEBA (Surface Heat Budget of the Arctic) was an interdisciplinary program to study the interactions of clouds, atmospheric radiation, and the surface energy balance over the Arctic Ocean.
