The Unexploited Treasures of Hydrological Observations Beyond Streamflow for Catchment Modeling

WIREs Water, Volume 12, Issue 2, March/April 2025.
Caption: In situ and satellite‐based observations of hydrological variables beyond streamflow are valuable to improve modeling catchment hydrology (modified from Fisher 2005; CC BY‐SA 4.0). ABSTRACT While measured streamflow is commonly used for hydrological model evaluation and calibration, an increasing amount of data on additional hydrological ...

Airborne observations of fast-evolving ocean submesoscale turbulence

Communications Earth & Environment
Ocean images collected by astronauts onboard the Apollo spacecraft more than 50 years ago revealed a large number of ocean eddies, with a size between 1 and 20 km.

Estimating Wind Direction and Wind Speed Over Lakes With Surface Water Ocean Topography and Sentinel‐1 Satellite Observations

Earth and Space Science, Volume 12, Issue 3, March 2025.
Abstract Wind at the water‐air interface is an important driver of hydrologic and biogeochemical processes in lakes. Satellite synthetic aperture radar (SAR) is commonly used over the ocean to retrieve wind fields using backscatter coefficients which are sensitive to wind‐driven surface water roughness; however, its application to lakes has been ...

Monitoring and Modeling the Soil‐Plant System Toward Understanding Soil Health

Reviews of Geophysics, Volume 63, Issue 1, March 2025.
Abstract The soil health assessment has evolved from focusing primarily on agricultural productivity to an integrated evaluation of soil biota and biotic processes that impact soil properties. Consequently, soil health assessment has shifted from a predominantly physicochemical approach to incorporating ecological, biological and molecular microbiology

Submesoscale Eddy Contribution to Ocean Vertical Heat Flux Diagnosed From Airborne Observations

Geophysical Research Letters, Volume 52, Issue 2, 28 January 2025.
Abstract Submesoscale eddies (those smaller than 50 km) are ubiquitous throughout the ocean, as revealed by satellite infrared images. Diagnosing their impact on ocean energetics from observations remains a challenge. This study analyzes a turbulent field of submesoscale eddies using airborne observations of surface currents and sea surface temperature,

Exploring the Characteristics of Ocean Surface Winds at High Resolution With Doppler Scatterometry

Geophysical Research Letters, Volume 51, Issue 23, 16 December 2024.
Abstract Ocean wind plays a fundamental role in the Earth's climate system by transporting heat, moisture, and gases globally while mediating their exchange with the ocean. How, and at what scales these processes occur is an active area of research, and modeling studies suggest that the strongest vertical transport and air‐sea exchanges occur at small ...

Machine‐Learning Based Multi‐Layer Soil Moisture Forecasts—An Application Case Study of the Montana 2017 Flash Drought

Water Resources Research, Volume 60, Issue 10, October 2024.
Abstract Soil moisture (SM) is an essential climate variable, governing land‐atmosphere interactions, runoff generation, and vegetation growth and productivity. Timely forecasts of SM spatial distribution and vertical profiles are needed for early detection and prediction of potential droughts.

Multiwavelength Aerosol Scatterometer for Airborne Experiments to Study the Optical Properties of Stratospheric Aerosol

Journal of Atmospheric and Oceanic Technology, 1999
In the recent past the role of polar stratospheric clouds (PSCs) and of stratospheric aerosol in polar ozone depletion raised the attention of the scientific community (Solomon 1990; Fiocco et al. 1997). The understanding of PSCs in terms of concentrations of particles, sizes, optical parameters, formation processes, and microphysics is relevant for ...

Observing System Simulation Experiments Exploring Potential Spaceborne Deployment Options for a Differential Absorption Radar Measuring Marine Surface Pressures

Earth and Space Science, Volume 11, Issue 10, October 2024.
Abstract A new technology for remote measurements of marine surface pressure has been proposed, employing a V‐band differential absorption radar and a radiometric temperature sounder to calculate the total column atmospheric mass. Observing System Simulation Experiments (OSSEs) are performed to evaluate the potential impact of Spaceborne Marine Surface
