Evaluating Evapotranspiration Simulation Performance in 30 Conceptual Hydrological Models: Insights Into ET Representation Across Diverse Climates

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Existing comparative studies on conceptual hydrological model structures have generally focused on streamflow, with less attention to evapotranspiration (ET). Yet, appropriate ET representation in conceptual models is crucial for obtaining reliable hydrological simulations, especially under climate change and in ungauged basins.

Estimation of vertically integrated liquid water contents in the atmosphere

open access: yesAntarctic Record, 1991
A 5-year project of "Antarctic Climate Research (ACR)" started in 1987. One of the main projects of the ACR is an observation of clouds and precipitation.

Self-balancing microwave comparison radiometer

open access: yesElectronics Letters, 1965
A 3cm radiometer evolved from Allred's 3 Mc/s system is described. The sum and difference of the voltages from an aerial and a controllable noise source are formed in a magic-T hybrid and correlated. The correlator output, which is zero only for equal aerial and reference powers, is used to adjust the reference to equality.

Observation‐Constrained Physical Snow Water Equivalent Simulations Using a Physics‐Guided Machine Learning Approach

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Estimating daily snow water equivalent (SWE) is critical for hydrological and climate applications, yet physical models often struggle to represent SWE, especially its interannual anomalies. In this study, we developed a hybrid physics‐guided machine learning (ML) model (hybrid model), by augmenting the Community Land Model 4.0 SWE simulations

Soil Moisture Buffers the Impact of Precipitation Variability on Ecosystem Productivity

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Water availability governs ecosystem productivity, yet estimates of vegetation sensitivity to water can differ greatly depending on whether the sensitivity is examined spatially or temporally. In particular, the spatial sensitivity is often reported to be much stronger than temporal sensitivities, leading to highly uncertain projections of ...

Methods of research of radiothermal radiation of cryospheric objects in the microwave range [PDF]

open access: yesE3S Web of Conferences
Many cryospheric formations on Earth have an inaccessible location. For example, when studying ice sheets located on the water surface, at the initial moment of ice formation, it becomes difficult to take samples.

Satellite‐Based Estimation of Near‐Surface Specific Humidity During Tropical Cyclones in the Western North Pacific and North Atlantic

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The near‐surface specific humidity is critical for accurately estimating the enthalpy flux from the ocean, which plays an important role in tropical cyclone intensification. However, under the severe oceanic and atmospheric conditions of these storms, even spaceborne microwave radiometers struggle to retrieve reliable humidity data.

2025 California Wildfire Observations Using Single Field‐of‐View Sounder Atmospheric Products (SiFSAP)

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Southern California wildfires result in a significant loss for Los Angeles and San Diego County from January 7 to 31, 2025. Palisades Fire and Eaton fires, the two largest fires that caused most of that damage, were observed by the infrared sounder CrIS and microwave sounder ATMS aboard a polar‐orbit satellite of the National Oceanic and ...
