Variability of Surface Radiation Budget over Arctic during Two Recent Decades from Perspective of CERES and ERA5 Data

This study focused on surface radiation budget, one of the essential factors for understanding climate change. Arctic budget was summarized and explained using a satellite product, Clouds Earth’s Radiant Energy System (CERES) Balanced Filled (EBAF), reanalysis data, ERA5. Net records indicated an increasing trend only in ERA5, with EBAF indicating decreasing Circle (AC; poleward from 65°N) 2000 to 2018. The differences net between product types due longwave downward radiation. extreme season selected according seasonality radiation, air temperature, sea ice extent. synthesized AC. Regardless tended increase summer annual trend. By contrast, winter, observed which ERA5 increased decreased. difference is represented each data. comprehensive information can be used analyze predict energy transport, interaction atmosphere Arctic.
