Changes in Relative Humidity Profiles over Earth’s Oceans
2023年7月21日 · Recently, we presented a classification of “primitive” relative humidity (RH) profiles into eight distinct clusters over Earth’s oceans, based on about 18 years (2003–20) of observations from the AIRS on NASA’s Aqua satellite. Here we investigate the seasonal variability and decadal trends, both in the vertical structure of these RH ...

2019年11月5日 · Here we combine recent satellite observations of clouds profiles and relative humidity profiles to document the diurnal variations of the water vapor and clouds vertical distributions over all...
A Satellite Climatology of Relative Humidity Profiles and …
2022年9月1日 · The six k-means global relative humidity–profile clusters over Earth’s oceans for clear-sky conditions (columns; organized from left to right according to their associated mean sea surface temperatures, SST ¯, from warm to cold). (row 1) Idealized mean RH profiles.
Temperature and Relative Humidity Profile Retrieval from Fengyun …
2021年5月11日 · The acquisition of real-time temperature and relative humidity (RH) profiles in the Arctic is of great significance for the study of the Arctic’s climate and Arctic scientific research.
Ground-based temperature and humidity profiling: combining …
This paper explores the synergy of combining ground-based IR, MW, and DIAL observations using an optimal-estimation retrieval framework, quantifying the reduction in the uncertainty in the retrieved profiles and the increase in information content as additional observations are added to IR-only and MW-only retrievals.
Temperature and Relative Humidity Profile Retrieval from …
2023年3月18日 · The proposed method is able to retrieve atmospheric temperature and relative humidity profile regions based on a NN algorithm from FY-3D/VASS data. The methods’ retrieval performance is compared with that obtained from NNs built only by FY-3D/HIRAS observations to evaluate the improvement of retrieval accuracy by using IR and MW measurements.
