Strengthening Atmospheric Greenhouse Effect at the Arctic North Slope of Alaska Site Evidenced by Long‐Term Records of the Downwelling Longwave Radiance Spectrum

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 14, 28 July 2025.
Abstract Arctic amplification, the accelerated warming of the Arctic compared to lower latitude, remains poorly understood, particularly regarding the role of clouds. In this study, we analyze 26 years of downwelling longwave radiation (DLR) measurements from an Extended‐range Atmospheric Emitted Radiance Interferometer (E‐AERI) at the US Department of

Identifying Wet Troposphere Delay in L‐Band InSAR Using Weather Radar Reflectivity

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract Synthetic Aperture Radar (SAR) pulses undergo variable propagation delays in the atmosphere due to changes in pressure, temperature, and humidity within the troposphere, causing large error in Interferometric SAR (InSAR) measurements of land surface displacement. Wet troposphere delay, resulting from condensed water and water vapor clouds, can

An Analytical Formula for Potential Water Vapor in an Atmosphere of Constant Lapse Rate

Terrestrial, Atmospheric and Oceanic Sciences, 2012
Accurate calculation of precipitable water vapor (PWV) in the atmosphere has always been a matter of importance for meteorologists. Potential water vapor (POWV) or maximum precipitable water vapor can be an appropriate base for estimation of probable ...
