“Water vapour accounts for roughly 50% of the modern greenhouse effect. Over continental regions, evapotranspiration (ET) is often limited by water availability. In this study, [the authors] spatially quantify how much of the total atmospheric water vapour evaporated most recently from land and calculate the relative contribution of that water vapour to the atmospheric radiative budget. Using a combination of tracer-enabled Earth system model simulations and radiative transfer calculations, [they were] able to explicitly quantify the 3D distribution of terrestrial vs. oceanic water vapour, and the spatial contribution of each to the surface and top of atmosphere radiative budgets. [They found] that over many continental regions, more than half of the total column-integrated water vapour originates from land ET, and that this vapour contributes up to 30 W/m² of longwave radiation into the surface in the annual mean (about 10% of the total). Understanding how terrestrial ET impacts the base-state of water vapour distribution and the water vapour greenhouse effect is critical to understanding how and where changes in terrestrial ET, driven by climate change, land use, etc, will modify the radiative properties of the atmosphere and thus the climate system…”

Earth Is Getting Dimmer—and the Northern Hemisphere Is Losing Brightness Faster Than Scientists Expected
(New research challenges the idea that the hemispheres’ matching brightness is a fundamental property of the planet)

Water vapour is the most abundant greenhouse gas and the most powerful one. It can amplify the warming effect of other greenhouse gases, such as carbon dioxide and methane, by trapping more heat in the atmosphere. This means that as the planet gets hotter, more water evaporates, creating a vicious cycle of warming and water vapour. #WaterVapour #GreenhouseGas #ClimateChange

Cool dataset of #WaterVapour on #Copernicus #CDS shared by @OceanTerra but what really strikes me is the position of #GNSS obs - so many in Europe and so sparse everywhere else (just like many other measurements).

https://fediscience.org/@OceanTerra/109393759383840484

#CopernicusClimate just published a new dataset: atmospheric water vapor from homogeneous processing of #GNSS data from #EPN_CB & @IGSorg with uncertainty estimates contributing to @gcos_un

Thank you, all the contributors!
