Assimilation of solar‐induced fluorescence satellite observations in the European Centre for Medium‐Range Weather Forecasts integrated forecast system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This work demonstrates the potential of the assimilation of satellite solar‐induced fluorescence (SIF) retrievals at eight‐day and 0.1° resolutions in the integrated forecast system (IFS), developed at the European Centre for Medium‐Range Weather Forecasts (ECMWF), at global scale, to provide a more realistic representation of the vegetation temporal ...

Potential soil moisture products from the aquarius radiometer and scatterometer using an observing system simulation experiment [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2013
Using an observing system simulation experiment (OSSE), we investigate the potential soil moisture retrieval capability of the National Aeronautics and Space Administration (NASA) Aquarius radiometer (L-band 1.413 GHz) and scatterometer (L-band, 1.260 ...

Polar‐low track prediction using machine‐learning methods

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Machine‐learning models are developed to produce reliable and efficient forecasts of polar‐low (PL) trajectories 12 hours ahead. A temporal model (RLSTM) benefiting from the rolling‐forecast strategy, improves overall prediction accuracy and is suitable for quick experimentation, while a spatiotemporal model (PL‐UNet), incorporating both historical and

Retrieval and Attribution of Tropical Cyclone Vertical Tilt From SAR and Infrared Satellite Imagery

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Tropical cyclones (TCs) are destructive natural hazards, and their vertical tilt, defined as the displacement between the sea surface center and cloud top center, plays a key role in storm structure and intensity changes. This study constructed a global satellite‐based tilt data set from 1,024 paired synthetic aperture radar (SAR) and infrared

Sudden Shift From Drought to Flood May Be Infrequent in Debris‐Flow Events in Southwest China: Evidence From Antecedent Hydrometeorological Fingerprints

Atmospheric Science Letters, Volume 27, Issue 3, March 2026.
Using reanalysis meteorological data and remotely‐sensed soil moisture, we examined antecedent hydrometeorological fingerprints of debris flows in Southwest China (2008–2018). Results show that about 80% of events occurred after anomalously high temperatures, while soils were predominantly wet (96.6%).

Pseudo‐diffusivity characteristic curves for surface–rootzone soil hydrologic connectivity

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract Accurate quantification of the rootzone soil moisture (θ) dynamics and hydrologic thresholds is important to advance sustainable agricultural water management and drought monitoring. Various low‐pass filters are popularly used to generate a first‐order approximation of θ, referred to here as θ̂$\hat{\theta }$, from temporally smoothed and ...

THE SCATTEROMETER AS A PRESSURE SENSOR

Gayana, 2004
The UW Planetary Boundary Layer (PBL) model is used to derive surface pressure fields from scatterometer surface measurements. After a decade of comparison with NMC wind products, it is clear that the combination of the scatterometer and the PBL model ...

Impact of Ocean Currents on Wind Stress in the Tropical Indian Ocean

Remote Sensing, 2022
This study examines the effect of surface currents on the bulk algorithm calculation ofwind stress estimated using the scatterometer data during 2007–2020 in the Indian Ocean. In the study region as a whole, the wind stress decreased by 5.4% by including
