Simulation and validation of Arctic radiation and clouds in a regional climate model
A regional atmospheric climate model has been applied to simulate the Arctic climate north of 65N at a 50 kmhorizontal resolution for January and July 1990. The monthly mean components of the surface radiative balanceand clouds using ECHAM3 parameterization have been described and compared with data...
