Satellite data are used to quantify and examine the bias in the outgoing long-wave
(LW) radiation over North Africa during MayJuly simulated by a range of climate
models and the Met Office global numerical weather prediction (NWP) model.
Simulations from an ensemble-mean of multiple climate models overestimate
