Brief communication: Evaluating Antarctic precipitation in ERA5 and CMIP6 against CloudSat observations
International audience CMIP5, CMIP6, and ERA5 Antarctic precipitation is evaluated against CloudSat data. At continental and regional scales, ERA5 and the median CMIP models are biased high, with insignificant improvement from CMIP5 to CMIP6. However, there are fewer positive outliers in CMIP6. AMIP...
