Abstract:
The Surface Heat Budget in the Arctic Ocean (SHEBA) is a coordinated
project to investigate the role of arctic climate in global
change. The primary goals of SHEBA are:
1. To determine the ocean-ice-atmosphere processes that control the
surface albedo and cloud-radiation feedback mechanisms over arctic
pack ice, and to use this information to demonstrably
... improve models
of arctic ocean-atmosphere-ice interactive processes,
2. To develop and implement models that improve the simulation of the
present day arctic climate, including its variability, utilizing
coupled global climate models
This case study presents data from 1 May 1998 to 31 July 1998 and
covers a region from 65N to 90N latitude and from 180W to 120W
longitude.
The data for this experiment is under Working Group 5 (Polar Clouds)
of the GEWEX Cloud System Study (GCSS) is to improve the
parameterization of precipitating convective cloud systems in global
climate models (GCMs) and numerical weather prediction models through
an improved physical understanding of cloud system processes.
