Observing Systems Simulation Experiments of Hypothetical Hourly Global Coverage of Microwave Satellite Radiances: Imbalance and Adaptive Observation Error Inflation

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract This study investigates the potential impacts of frequent global coverage of satellite microwave radiances using a global atmospheric data assimilation (DA) system. Observing Systems Simulation Experiments (OSSEs) were performed using the Local Ensemble Transform Kalman Filter with the Nonhydrostatic Icosahedral Atmospheric Model (NICAM ...

Contribution of Land Surface Temperature (TCI) to Vegetation Health Index: A Comparative Study Using Clear Sky and All-Weather Climate Data Records

open access: yesRemote Sensing, 2018
The Vegetation Health Index (VHI) is widely used for monitoring drought using satellite data. VHI depends on vegetation state and thermal stress, respectively assessed via (i) the Vegetation Condition Index (VCI) that usually relies on information from ...

Properties of Positive Narrow Bipolar Events Observed in South‐Eastern France

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Narrow bipolar events (NBEs) are brief intracloud discharges that generate the most intense radiation in the high frequency and very high frequency radio bands. Their occurrence is statistically correlated with strong convection and typically takes place in the upper regions of thunderclouds.

Medicane characteristics from high‐resolution satellite radar observations

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
This study uses high‐resolution observations from satellite synthetic aperture radar (SAR) to reveal that medicanes, cyclones with tropical features in the Mediterranean basin, have dynamical characteristics with attributes comparable with those of tropical cyclones of similar intensities, but smaller outer sizes and Rossby numbers.

Meteosat‐6 experiences anomaly

open access: yesEos, Transactions American Geophysical Union, 1994
Following a successful launch on November 20, 1993, the European Space Agency's Meteosat‐6 satellite began to experience an anomaly in the functioning of its radiometer, which affects the spacecraft's full operational capabilities.The anomaly was discovered in December during quality checks of the infrared images.

Diurnal evolution of cloud base heights in convective cloud fields from MSG/SEVIRI data [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
This study shows that it is possible to retrieve the temporal evolution of cloud base heights in convective broken cloud fields from data of the SEVIRI instrument onboard the geostationary satellite Meteosat-9.

A New Database of Global and Direct Solar Radiation Using the Eastern Meteosat Satellite, Models and Validation

open access: yesRemote Sensing, 2014
We present a new database of solar radiation at ground level for Eastern Europe and Africa, the Middle East and Asia, estimated using satellite images from the Meteosat East geostationary satellites.

Operational all‐sky assimilation of geostationary infrared water‐vapour channels in the regional ICON‐D2 model with an ensemble Kalman filter

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
Though many studies have shown potential benefit in assimilating all‐sky infrared radiances from geostationary satellites, at numerical weather prediction centres it is still common practice to assimilate clear‐sky radiances. We present the operationalization of the all‐sky assimilation of the spinning enhanced visible and infrared imager (SEVIRI ...
