Radiosondes are a means for regular observations of water vapor fluxes. However, their data are sparse in space and time. A more complete picture is provided by reanalysis assimilating these data. However, a statistically representative check of the reanalysis estimates of the water vapor fluxes far from regularly operating weather stations is difficult. The previously proposed and developed method of satellite radiothermovision makes it possible to reconstruct the vertically integrated advective water vapor fluxes from satellite microwave radiometry. In this work, for the first time, the results of direct comparisons of long (5 year) time series of zonal vertically integrated daily water vapor fluxes based on the data of radiosondes, reanalysis, and satellite radiothermovision are performed and presented. It is shown that all the data series are statistically reliably correlated (at a confidence level of 0.995). The regression factor between the fluxes from reanalysis and satellite radiothermovision was close to 1, but with a noticeable bias (the latter were about 60 kg\/(m\u00b7s) less on average). Grounds are given for the hypothesis that calculations based on satellite radiothermovision mainly characterize water vapor fluxes in the lower troposphere (up to heights of about 4 km). Its verification, as well as the analysis of the noted cases of violation of the correlation between the fluxes from satellite radiothermovision and reanalysis, requires further research.<\/jats:p>","DOI":"10.3390\/rs13091639","type":"journal-article","created":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T21:25:56Z","timestamp":1619126756000},"page":"1639","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Comparison of Vertically Integrated Fluxes of Atmospheric Water Vapor According to Satellite Radiothermovision, Radiosondes, and Reanalysis"],"prefix":"10.3390","volume":"13","author":[{"given":"Dmitry","family":"Ermakov","sequence":"first","affiliation":[{"name":"Fryazino Department of Kotelnikov Instiute of Radioengineering and Electorincs, Russian Academy of Sciences, Vvedenskogo Sq. 1, 141120 Fryazino, Russia"},{"name":"Space Research Institute, Russian Academy of Sciences, Profsoyuznaya Str. 84\/32, 117997 Moscow, Russia"}]},{"given":"Alexey","family":"Kuzmin","sequence":"additional","affiliation":[{"name":"Space Research Institute, Russian Academy of Sciences, Profsoyuznaya Str. 84\/32, 117997 Moscow, Russia"}]},{"given":"Evgeny","family":"Pashinov","sequence":"additional","affiliation":[{"name":"Space Research Institute, Russian Academy of Sciences, Profsoyuznaya Str. 84\/32, 117997 Moscow, Russia"}]},{"given":"Victor","family":"Sterlyadkin","sequence":"additional","affiliation":[{"name":"Moscow Institute of Radiotechniki Electroniki i Avtomatiki (MIREA)\u2014Russian Technological University, 119454 Moscow, Russia"}]},{"given":"Andrey","family":"Chernushich","sequence":"additional","affiliation":[{"name":"Fryazino Department of Kotelnikov Instiute of Radioengineering and Electorincs, Russian Academy of Sciences, Vvedenskogo Sq. 1, 141120 Fryazino, Russia"}]},{"given":"Eugene","family":"Sharkov","sequence":"additional","affiliation":[{"name":"Space Research Institute, Russian Academy of Sciences, Profsoyuznaya Str. 84\/32, 117997 Moscow, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Barry, R.G., and Chorley, R.J.
