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 ...

Using Machine Learning to Generate a GISS ModelE Calibrated Physics Ensemble (CPE)

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.
Abstract A neural network (NN) surrogate of the NASA GISS ModelE atmosphere (version E3) is trained on a perturbed parameter ensemble (PPE) spanning 45 physics parameters and 36 outputs. The NN is leveraged in a Markov Chain Monte Carlo (MCMC) Bayesian parameter inference framework to generate a second posterior constrained ensemble coined a ...

Constructing High-Precision and Spatial Resolution Precipitable Water Vapor Product Using Multiple Fusion Models

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Water vapor is a critical parameter in the earth's climate system, affecting precipitation and global warming. Precipitable water vapor (PWV) is a measure of atmospheric water vapor content that can be obtained by multiple methods.

Testing of the LSST's photometric calibration strategy at the CTIO 0.9 meter telescope [PDF]

, 2018
The calibration hardware system of the Large Synoptic Survey Telescope (LSST) is designed to measure two quantities: a telescope's instrumental response and atmospheric transmission, both as a function of wavelength.

Seasonality and Albedo Dependence of Cloud Radiative Forcing in the Upper Colorado River Basin

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 6, 28 March 2025.
Abstract Mountains create and enhance their own clouds, which both scatter and absorb shortwave radiation from the sun and absorb and re‐emit land surface and atmospheric longwave radiation. However, the impacts of clouds on the surface radiation balance in high elevation snowy mountain terrain are poorly explored.
