The Role of Lightning in Atmospheric Chemistry

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

Strong Diurnal‐Dependent Meteorological Control on Long‐Term Variations of Cloud Droplet Number Concentration

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract While long‐term cloud droplet number concentration (CDNC) changes are commonly attributed to aerosols, the role of meteorological factors remains poorly explored. Here, we perform a time‐resolved contribution analysis of long‐term CDNC variations using nearly two decades of geostationary observations over four Atlantic subtropical regions. The

Implementation of the Deep Blue Aerosol Algorithm on Geostationary Satellite Data

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract National Aeronautics and Space Administration's Deep Blue (DB) aerosol project aims to produce consistent, long‐term climate data records of atmospheric aerosol properties using satellite observations. The DB algorithm has been extensively applied to low Earth orbit (LEO) sensors, including the Moderate Resolution Imaging Spectroradiometer and

A WRF Simulation of an Episode of Contrails Covering the Entire Sky

Atmosphere, 2016
On 21 September 2012 the entire sky was covered by contrails over the Gulf of Lyon (NW of the Mediterranean basin). These clouds were well recorded by ground observers as well as by Meteosat imagery.

Coupling UV Camera‐Derived SO2 Emission Rate and Thermal Output at Mount Etna: A Decadal Analysis Across Eruptive Phases

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract At persistently degassing open‐vent volcanoes, SO2 emissions are especially useful to capture the transition from quiescence to eruption, though accurate quantification is challenged by complex volcanic plume dynamics and limited resolution of observations. Here, we present an exceptionally long (∼10–year) record of SO2 emission rates from the

Climate Data Records from Meteosat First Generation Part I: Simulation of Accurate Top-of-Atmosphere Spectral Radiance over Pseudo-Invariant Calibration Sites for the Retrieval of the In-Flight Visible Spectral Response

Remote Sensing, 2018
Meteosat First-Generation satellites have acquired more than 30 years of observations that could potentially be used for the generation of a Climate Data Record.

African and Atlantic short-term climatic variations described from Meteosat water vapor channel [PDF]

Annales Geophysicae, 1995
Pluriannual series of Meteosat-2 water vapor (WV) images are used to build average maps of decadal and monthly brightness temperatures in the 6.3 µm channel. This processing is applied to all the 3-hourly scenes, clear or cloudy, for July 1983 to July

Soil Moisture Impact on Convective Initiation

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract The influence of soil moisture on convective storm initiation remains an open question, with previous studies showing conflicting results regarding whether storms preferentially form over wet or dry soils. Here, we analyze the soil moisture‐convection relationship using satellite observations across North America, Africa, and Australia from ...

The underappreciated roles of fog and dew on vegetation and biocrusts

New Phytologist, Volume 251, Issue 1, Page 46-63, July 2026.
Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

Un simple algorithme mono-canal pour l’estimation de la température de surface à partir des images du canal infrarouge thermique de METEOSAT

Revue des Énergies Renouvelables, 2010
La température de surface est utilisée dans plusieurs applications, notamment en agro météorologie, climatologie et les études environnementales. Dans cette étude, nous avons développé un algorithme mono-canal pour l’estimation de la température de ...
