The radiation budget of the atmosphere over the Arctic compiled from the ISCCP-FD data sets (preliminary results)

元データ 国立極地研究所

概要

The technological advancements of the past two to three decades enabled the establishment of space-borne observational systems to measure worldwide clouds and related radiation fields at the top of the atmosphere. This data when combined with further information on the thermodynamic state of the atmosphere and ground allows for estimates of the radiation budget at ground and within the atmosphere. This information is urgently required to calibrate the output of climate models and to understand current changes in the climate system. Results of the International Satellite Cloud Climatology Project (ISCCP) are here presented and compared with another but similar data set of the Global Energy and Water Cycle Experiment (GEWEX-SRB) and with ground-based measurements. This data describes details in space and time of the variability of radiation budget parameters at the surface and at the top of the atmosphere over the entire globe. Over the Arctic ice fields-our studies concern areas poleward of about 60°N-considerable uncertainties of more than 20Wm^(-2) still exist in both the long-wave and short-wave budget components at ground.
