Vapor transport
Annual averages of precipitable water and integrated vapor transport are derived from the ECMWF/ERA5 atmospheric reanalysis and sourced from the Copernicus Climate Change Service. The charts show the percent difference from the 1991–2020 average as well as the linear trend from 1940 to the most recently completed year.
