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

A Simple Emulator That Enables Interpretation of Parameter‐Output Relationships, Applied to Two Climate Model PPEs

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 5, May 2025.
Abstract We present a new additive method, referred to as sage for Simplified Additive Gaussian processes Emulator, for emulating climate model Perturbed Parameter Ensembles (PPEs). sage estimates the value of a climate model output as the sum of additive terms.

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 ...

Impacts of Anthropogenic Emission Change Scenarios on U.S. Water and Carbon Balances at National and State Scales in a Changing Climate

Earth's Future, Volume 13, Issue 4, April 2025.
Abstract The U.S. water supply and carbon sequestration are increasingly threatened by future climate change and air pollution. This study investigates the ecohydrological responses to the individual and combined impacts of climate change and anthropogenic emission (referring only to air pollutants, excluding greenhouse gases) changes at two spatial ...
