Evaluation of Clouds in Version 1 of the E3SM Atmosphere Model With Satellite Simulators
Abstract This study systematically evaluates clouds simulated by the Energy Exascale Earth System Model Atmosphere Model version 1 (EAMv1) against satellite cloud observations. Both low‐ (1°) and high‐ (0.25°) resolution EAMv1 configurations generally underestimate clouds in low latitudes and midlat...
