GRENet: GNSS‐Enhanced Radar Extrapolation Network for Precipitation Nowcasting

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Accurate precipitation nowcasting is one of the most challenging tasks in atmospheric sciences. The current methods of nowcasting primarily rely on inferring precipitation from radar reflectivity, which inevitably leads to uncertainties in forecasts due to the limitations of single radar data in capturing the detailed initial conditions of ...

Deep neural network enhanced global tropospheric zenith delay model

, 2019
With the growing use of airborne platforms in Earth observation, accurate tropospheric delay corrections across various altitudes have become essential. Most existing tropospheric delay models are referenced to the Earth’s surface and rely on analytical ...

Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 1. Reconstruction of the Dynamics of the 11 September 1930 Event

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.

Updates, Examples and Validation of the Global Ionosphere Thermosphere Model

Space Weather, Volume 24, Issue 5, May 2026.
Abstract This study provides an updated description, example simulations, and validation of the Global Ionosphere Thermosphere Model (GITM). The updates to GITM include using an exothermic semi‐implicit chemistry scheme that no longer requires an altitude dependent heating efficiency; an ionospheric wind‐driven dynamo; improved neutral, ion, and ...

Cerebral blood velocity responses during and after sprint interval exercise in healthy young adults

Physiological Reports, Volume 14, Issue 9, May 2026.
Abstract This study investigated the middle (MCAv) and posterior (PCAv) cerebral artery blood velocity and end‐tidal carbon dioxide (PETCO2) responses during sprint interval exercise (SIE). We also examined the relationships between MCAv, PCAv and blood pressure during the 60 min post SIE.

Challenges and Strategies in Managing Pulmonary Arterial Hypertension Within the Indian Healthcare System: A Consensus Statement From the Pulmonary Vascular Research Institute India Taskforce

Pulmonary Circulation, Volume 16, Issue 2, April 2026.
ABSTRACT Pulmonary arterial hypertension (PAH) in India is a substantial yet under‐recognized contributor to cardiovascular morbidity and mortality. Its progressive course, nonspecific early manifestations, and heterogeneous aetiologies often lead to delayed diagnosis and fragmented care.

A Window‐Augmented Machine Learning Approach for Direct GNSS Precipitable Water Vapor Retrieval

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Global Navigation Satellite Systems (GNSS) provide an effective means for remote sensing of precipitable water vapor (PWV). However, conventional GNSS‐based PWV retrieval approaches rely heavily on auxiliary meteorological parameters, which are frequently unavailable in real time, while most direct retrieval methods use station data aggregated
