Radiative fluxes at high latitudes



[1] Newly improved satellite products and surface observations provide an opportunity to revisit remote-sensing capabilities for estimating shortwave (SW) radiative fluxes at high latitudes, location of disagreement among models and observations. Estimates of SW fluxes from the Moderate Resolution Imaging Spectro-radiometer (MODIS) are evaluated against land observations from the Baseline Surface Radiation Network (BSRN), from Greenland, and unique buoy measurements. Results show that the MODIS products are in better agreement with observations than those from numerical models. Therefore, the large scale satellite based estimates should be useful for model evaluation and for providing information in formulating energy budgets at high latitudes.
