Antarctic sea ice concentration in the Brazilian Earth System Model Simulations
Sea ice is an important and complex component of the Earth???s system, acting as both an indicator and an amplifier of climate change. Here, we investigated the ability of the Brazilian Earth System Model (BESM-OA2.5) and four state-of-the-art climate models participating in the fifth phase of the C...

Sea ice is an important and complex component of the Earth???s system, acting as both an indicator and an amplifier of climate change.

We validated the sea ice model???s performance using satellite data from 1980 to 2005 and calculated the skill and RMSE of each model.
