The Influence of Interactive Sea Surface Temperatures on Self‐Aggregation in Channel Domain Radiative‐Convective Equilibrium

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Convective self‐aggregation describes the spontaneous organization of convection that occurs in radiative‐convective equilibrium (RCE) simulations. Here, we conduct RCE simulations coupled to 2‐ and 20‐m slab ocean models in a 3D channel domain to assess the influence of interactive sea surface temperatures (SST) on self‐aggregation.

Exposing and Reducing Biases of Simulating Mixed‐Phase Clouds in the Convection‐Permitting E3SM Atmosphere Model: Lessons From an Arctic Cold‐Air Outbreak

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Mixed‐phase clouds modulate the water and energy cycles of high‐latitude regions, yet their liquid‐ice phase partitioning has long been poorly simulated in climate models. Here, simulations of Arctic mixed‐phase clouds by the Simple Cloud‐Resolving E3SM Atmosphere Model (SCREAM) are assessed against large‐eddy simulations, satellite data, and ...

Capturing Extreme Water Vapor and Instability With High‐Resolution GNSS Monitoring

Atmospheric Science Letters, Volume 27, Issue 2, February 2026.
This study used data from a high‐resolution Global Navigation Satellite System network (< 10 km spacing), including private stations, to analyze water vapor structure during a heavy rainfall event in Japan. The network captured localized extreme precipitable water vapor (> 70 mm) and a moist absolutely unstable layer near the humid core.

Global, spatially explicit modelling of zenith wet delay with XGBoost

Journal of Geodesy
AbstractRadio signals transmitted by Global Navigation Satellite System (GNSS) satellites experience tropospheric delays. While the hydrostatic part, referred to as zenith hydrostatic delay (ZHD) when mapped to the zenith direction, can be analytically modelled with sufficient accuracy, the wet part, referred to as zenith wet delay (ZWD), is much more ...

Economic and Technical Assessment of Wind Potential Using SARIMAX Time Series Models: Wind Speed Forecasting and Analysis

Energy Science &Engineering, Volume 14, Issue 2, Page 973-998, February 2026.
The wind energy potential of Khaf was evaluated for 2025 using 15 years of wind data combined with advanced forecasting models, SARIMAX and Prophet. This integrated framework enables precise estimation of wind power density and optimal turbine selection, paving the way for the efficient and sustainable development of wind farms in the region.

Determining precipitable water in the atmosphere of Iran based on GPS zenith tropospheric delays

Annals of Geophysics, 2014
Precipitable water (PW) is considered as one of the most important weather parameters in meteorology. Moreover, moisture affects the propagation of the Global Positioning System’s (GPS) signals.

An inter-comparison study to estimate zenith wet delays using VLBI, GPS, and NWP models [PDF]

Earth, Planets and Space, 2014
Water vapour is a key variable in atmospheric processes and plays a crucial role in atmospheric motions on a wide range of scales in space and time. The water vapour content is approximately proportional to the zenith wet delay (ZWD) which, in turn, constitutes a crucial parameter in geodetic microwave space techniques (VLBI and GPS).

Water Vapor Vertical Distribution on Mars After Six Years of TGO/NOMAD Solar Occultations: 1. Global Climatology

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We present vertical profiles of water vapor obtained during six continuous years of solar occultation observations in the infrared by the Nadir and Occultation for MArs Discovery (NOMAD) instrument on board Trace Gas Orbiter. The retrievals have been performed with an inversion code previously applied to smaller samples of this data set, but ...

Integrating SWOT With Multi‐Source Satellite Observations for Near‐Daily Reservoir Water Level Monitoring

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Reservoirs play a crucial role in global water resource management. Monitoring reservoir hydrologic dynamics is critical for assessing climate variability and anthropogenic regulation. However, traditional satellite altimetry faces multiple challenges hindering high frequency and accuracy water level monitoring.
