Evaluation and Adjustment of Precipitable Water Vapor Products from FY-4A Using Radiosonde and GNSS Data from China

Atmosphere
The geostationary meteorological satellite Fengyun-4A (FY-4A) has rapidly advanced, generating abundant high spatiotemporal resolution atmospheric precipitable water vapor (PWV) products.

GREAT/SOFIA atmospheric calibration

, 2012
The GREAT observations need frequency-selective calibration across the passband for the residual atmospheric opacity at flight altitude. At these altitudes the atmospheric opacity has both narrow and broad spectral features.

Significant Increase in African Water Vapor over 2001–2020

Remote Sensing
Atmospheric water vapor is not only a key element of the global hydrological cycle but also the most abundant greenhouse gas. The phase transition and transportation of water vapor are essential for maintaining global energy balance and regulating ...

Transit Detection in the MEarth Survey of Nearby M Dwarfs: Bridging the Clean-First, Search-Later Divide

, 2012
In the effort to characterize the masses, radii, and atmospheres of potentially habitable exoplanets, there is an urgent need to find examples of such planets transiting nearby M dwarfs. The MEarth Project is an ongoing effort to do so, as a ground-based

Enhanced Retrieval of Precipitable Water Vapor Over Land: An Approach for Algorithmic Improvement and Performance Assessment

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Precipitable water vapor (PWV) is a critical variable for monitoring extreme weather events, particularly precipitation. Accurate retrieval of PWV is therefore essential in hydrology and meteorology.
