Description

Over land we find the signal of increasing near-surface water vapour while saturation levels have decreased reasonably robust. Drivers of this, at large scales at least, are reasonably well understood. Over oceans however, uncertainty remains very large with very little agreement between in situ, reanalyses and modelled estimates, very limited spatial coverage of in situ observations, and challenges in producing comparable estimates from remotely sensed platforms. Here I will present recent work exploring differences and potential sources of error between the in situ HadISDH near-surface humidity product, ERA5 reanalysis and a selection of CMIP6 models.
