The United States Magnetotelluric Array and the National Impedance Map

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

Attributing Upper‐Tropospheric Warm Biases in CMIP6 Models to Ice Cloud‐Radiation Interaction Deficiencies Over Tropical Oceans

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
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),

Interseismic, Coseismic, and Early Postseismic Slip Associated With the 2025 Mw 8.8 Kamchatka Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Unraveling the surface deformation and fault kinematics during the seismic cycle is crucial for understanding earthquake physics. Herein, we use geodetic and seismic observations to quantify the interseismic coupling, coseismic rupture, and postseismic afterslip associated with the 2025 Mw 8.8 Kamchatka earthquake.

Orographic and convective gravity waves above the Alps and Andes mountains during GPS radio occultation events – a case study [PDF]

open access: yes, 2017
The significant distortions introduced in the measured atmospheric gravity wavelengths by soundings other than in vertical and horizontal directions, are discussed as a function of elevation angle of the sounding path and the gravity waves aspect ratio ...
