Predicting Head Loss and Hydraulic Roughness of Channel‐Spanning Large Wood Jams
Abstract Log jams enhance hydraulic and geomorphic diversity in river corridors. Channel‐spanning log jams induce backwatering, increase local flow heterogeneity, promote sediment deposition, and improve aquatic habitat diversity. Despite their increasing popularity in river restoration, predicting their hydraulic effects remains a challenge.

A First Attempt at Reconstructing FengYun‐4B Stratified Precipitable Water Using GNSS
Abstract Layer Precipitable Water (LPW) characterizes the vertical structure of atmospheric moisture and is essential for accurate weather forecasts. China's FY‐4B satellite delivers near‐real‐time LPW products, but is constrained by large uncertainties.

Abstract Subglacial processes are key to glacier dynamics but remain poorly constrained due to limited in situ observations. We use continuous seismic and Global Navigation Satellite System (GNSS) measurements to investigate summer basal conditions at Sermeq Kujalleq in Kangia (SKK; Jakobshavn Isbræ), Kalaallit Nunaat (Greenland).

Unconstrained GNSS Water Vapor Tomography With Real Data and LEO Augmentation
Abstract The availability of four complete GNSS constellations (GPS, GLONASS, BeiDou and Galileo) offers, for the first time, the possibility of performing water vapor tomographic inversions that do not rely on external data. A tomographic model that includes no external constraints and requires no first guess and no virtual observations is described ...

Abstract We assess the impact of hydrometeor radiative effects on tropical and subtropical Pacific air temperature anomalies (TAA) using Coupled Model Intercomparison Project Phase 6 (CMIP6) model simulations and satellite data. CMIP6 models are grouped by their treatment of frozen hydrometeors: SON2 (explicit cloud and falling ice), SON1 (simplified),

Abstract A widely accepted global model of glacial isostatic adjustment (GIA) is based on ICE‐6G ice loading and 1D‐viscosity model VM5a, a viscosity profile which remains at odds with mantle convection constraints such as from geoid modeling. We explore 3D‐viscosity variations in models of GIA and show that a model with lateral viscosity variations ...
