Climatology and Trends in Spatial Scales of Extreme Precipitation Over Land in the Contiguous US
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Extreme precipitation (EP) poses a severe risk under a changing climate. Here we use daily gridded precipitation data (1980–2024) and a connected‐component labeling algorithm to characterize the climatology and regional trends of daily EP spatial scale over land in the contiguous United States (US).

A Signal‐Derived Retrieval Reduces Bias in TEMPO NO2
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.Abstract Satellite measurements of NO2 ${\text{NO}}_{2}$ are widely used for investigations of emissions, pollution exposure, and photochemical ozone production. The most commonly available data products compromise on accuracy and spatial resolution in favor of lower compute time.

Hidden Complexity in Reservoir Flow Regulation Revealed by Spectral Analysis
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Understanding reservoir regulation of streamflow is critical for hydrological modeling and ecohydrological assessments, yet our knowledge of how reservoirs preferentially modify flow variability remains limited. Here we apply spectral analysis to daily inflow‐outflow data from 205 US reservoirs, decomposing regulation effects into operational ...

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Soil inorganic carbon (SIC) is critical for carbon sequestration, infiltration, and climate modeling, yet quantifying its precise spatial distribution at continental scales remains challengings. We introduce a high‐resolution (30 m) CONUS SIC map using machine learning (ML) models trained on the ISRIC World Soil Information Service (WoSIS ...

Advanced 30/20 GHz multiple-beam antennas for communications satellites [PDF]
Design concepts under development utilize two separate spacecraft antenna systems, one uplink at 30 GHz and the other a downlink at 20 GHz, where each antenna provides multiple fixed and scanning beams.

The Role of Baseflow Data Assimilation in Hydrologic Modeling and Peak Flow Prediction
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Recent studies have revealed that subsurface water storage and flow pathways contribute a substantially larger share of streamflow than previously assumed. However, because representations of these subsurface contributions in most hydrologic models are uncertain and often biased, they can strongly influence simulated streamflow generation and ...

Streamflow in the United States: Characteristics, trends, regime shifts, and extremes
Scientific DataLong-term streamflow observations contain essential information for understanding hydrological changes and managing water resources. A continental-scale dataset or analysis of temporal streamflow change is still lacking across hydrologic gauges in the ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.Abstract Convection‐permitting dynamical downscaling (CPDD) allows for an explicit representation of the convective storms that generate tornadoes, hail, severe thunderstorm winds, and locally heavy precipitation. Possible changes in such hazardous convective weather (HCW) due to human‐induced climate change are therefore projected with higher ...

Assessment of economic factors affecting the satellite power system. Volume 2: The systems implications of rectenna siting issues [PDF]
The feasibility was evaluated of finding potential sites for Solar Power Satellite (SPS) receiving antennas (rectennas) in the continental United States, in sufficient numbers to permit the SPS to make a major contribution to U.S.
