Comparison of surface radiative flux data sets over the Arctic Ocean

摘要: [1] Recent satellite data analysis and reanalysis projects have provided an unprecedented wealth of sets relevant to surface energy budget in the Arctic Ocean. To assess how well we can reconstruct variations radiative fluxes used as boundary conditions force sea ice models, temperature, downwelling shortwave longwave (1) Cloud Surface Parameter Retrieval (CASPR), (2) International Satellite Climatology Project (ISCCP-FD), (3) National Centers for Environmental Prediction Reanalysis II (NCEP-R2), (4) European Centre Medium-Range Weather Forecast 40-Year (ERA-40) were evaluated over period November 1997 September 1998. At local scale accuracy these parameters was compared high-quality situ measurements from Heat Budget Ocean (SHEBA) seasonal cycle during particular storm events. The CASPR NCEP-R2 are closer SHEBA temperature. ISCCP-FD more accurate downward fluxes. ERA-40 agrees with basin consistency dominant spatial/temporal variability across different examined. All reproduce patterns associated cycle, but they vary their ability capture linked synoptic variability.
