A novel integrated water vapor (IWV) product from TROPOspheric Monitoring Instrument (TROPOMI) is validated together with a Global Ozone Instrument-2 (GOME-2) standard product. As reference, ground-based Navigation Satellite Systems (GNSS) IWV data in 235 European stations May 2018 to 2019 are used. Under cloud free situations, general comparison carried out. It suggests that TROPOMI exhibits l...

[1] Ensemble simulations of a regional climate model assuming smoke aerosol in the Amazon suggest that dynamic changes of cloud cover contributes to the radiative effect of the smoke on the diurnal cycles of surface fluxes and the depth and structure of planetary boundary layer (PBL). In addition to their local effects, the aerosol radiative forcing also appears to weaken or delay the circulati...

Extratropical cyclones are responsible for most of the precipitation and wind damage in the midlatitudes during the cold season, but there are still uncertainties on how they will change in a warming climate. A ubiquitous problem among general circulation models (GCMs) is a lack of cloudiness over the southern oceans that may be in part caused by a lack of clouds in cyclones. This study analyze...

Low-level stratiform clouds modulate California's coastal climate during the warm season. Previous work describing seasonal and daily variability of low cloudiness (CLC) suggests that in July, August, September southern CLC is under influence an additional driver, which has less impact northern California. In this work, we introduce link free-tropospheric moisture dictated by North American Mon...

Four previously identified patterns of meso-scale cloud organization in the trades — called Sugar, Gravel, Flowers, and Fish are studied using long-term records ground-based measurements, satellite observations reanalyzes. A deep neural network trained to detect these is applied imagery identify periods during which a particular pattern observed over Barbados Cloud Observatory. Surface-based re...

This study diagnoses the changes in Arctic clouds simulated by the Community Climate System Model version 3 (CCSM3) in a transient 2 3 CO2 simulation. Four experiments—one fully coupled and three with prescribed SSTs and/or sea ice cover—are used to identify themechanisms responsible for the projected cloud changes. The target simulation uses a T42 version of the CCSM3, in which the atmosphere ...
