Evaluation of surface meteorology parameters and heat fluxes from CFSR and ERA5 over the Pacific Arctic Region
Abstract Surface meteorological parameters and heat fluxes play a crucial role in air–sea (ice) interactions. In this study, the accuracy of surface meteorological parameters and air–sea heat flux data obtained from the Climate Forecast System Reanalysis (CFSR) and the fifth‐generation European Cent...

Abstract Surface meteorological parameters and heat fluxes play a crucial role in air–sea (ice) interactions. In this study, the accuracy of surface meteorological parameters and air–sea heat flux data obtained from the Climate Forecast System Reanalysis (CFSR) and the fifth‐generation European Center for Medium‐range Weather Forecasts Reanalysis (ERA5) over the Pacific Arctic Region were evaluated. Data from two buoys and 11 cruises provided by the Chinese Arctic Research Expedition were used in this evaluation. The observational data were independent of the reanalysis products. In open water, the meteorological data from CFSR and ERA5 corresponded reasonably well with the observational data. However, the heat flux data from both CFSR and ERA5 showed poor accuracy, especially for shortwave radiation.
