An improved cirrus detection algorithm MeCiDA2 for SEVIRI and its evaluation with MODIS [PDF]

Atmospheric Measurement Techniques, 2013
In this study, a substantially improved version of the Meteosat cirrus detection algorithm (MeCiDA2) will be presented, which now allows application to the full earth disc visible by the Meteosat satellite.

Estimation of Byram’s Fire Intensity and Rate of Spread from Spaceborne Remote Sensing Data in a Savanna Landscape

Fire, 2021
Fire behavior is well described by a fire’s direction, rate of spread, and its energy release rate. Fire intensity as defined by Byram (1959) is the most commonly used term describing fire behavior in the wildfire community.

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 ...

Exploring the Influence of Equatorial Waves on a Record‐Breaking Extreme Precipitation Event in Central Sahel: Insights From Convection Permitting Simulations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The floods of 01 September 2009 in Ouagadougou, Burkina Faso, were among the most severe in the Central Sahel's history, highlighting the region's persistent flood risk. This extreme precipitation event (EPE) was influenced by various atmospheric drivers, including Convectively Coupled Equatorial Waves (CCEWs).

Objective detection of gravity waves in Himawari‑8 imagery in support of aviation forecasting

Meteorologische Zeitschrift, 2020
In this paper, the applicability of an objective gravity wave detection method based on Gabor filter plus grating cell operators to Himawari‑8 geostationary satellite imagery is investigated for the visible, water vapor and infrared window bands.

Monitoring Atmospheric Ammonia From Geostationary Orbit: Contributions of GIIRS‐B and IRS Remote Sensors

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Ammonia (NH3) is a short‐lived atmospheric pollutant with significant environmental and health impacts. Monitoring NH3 remains challenging, as diurnal variability at local scales is still poorly documented. In this study, we analyze two years (July 2022–June 2024) of NH3 total columns from the Geostationary Interferometric Infrared Sounder ...

A Multiband Optical‐Radio View of Lightning Return Strokes Exposes Divergent 337/777 nm Emission Dynamics

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Simultaneous observations of ultraviolet (337 nm) and near‐infrared (777 nm) lightning emissions provide insight into streamer and leader processes. However, coordinated ground‐based measurements of these bands during return strokes remain scarce.
