The multiple global navigation satellite systems (multi-GNSS) bring great opportunity for the real-time retrieval of high-quality zenith tropospheric delay (ZTD), which is a critical quality for atmospheric science and geodetic applications.

Abstract SO2 flux and gas composition were measured during the 2021 flank eruption of Pacaya Volcano (Guatemala). The SO2 flux, measured with Tropomi, gradually rose from ∼2 to ∼30 kg/s over a 5 month period before the eruption. Field UV camera data showed that >95% of the SO2 was emitted from the summit crater.

A zenith tropospheric delay correction model based on the regional CORS network
Tropospheric delay is a primary error source in earth observations and a variety of radio navigation technologies. In this paper, the relationship between zenith tropospheric delays and the elevation and longitude of stations is analyzed using the zenith

Role of Shortwave Feedback in Non‐Linear Response to CO2 Forcing in GFDL CM4.0
Abstract Effective climate sensitivity (EffCS) is a key metric for quantifying climate change, yet its uncertainty remains large, primarily due to intermodel differences in cloud feedback. Here, we assess EffCS and climate feedback to an abrupt doubling (2xCO2) and quadrupling (4xCO2) of CO2 over 450 years in GFDL CM4.0. Both runs have comparable EffCS

Effect of stratosphere-troposphere exchange on the future tropospheric ozone trend [PDF]
This paper investigates the impact of circulation changes in a changed climate on the exchange of ozone between the stratosphere and the troposphere. We have identified an increase in the net transport of ozone into the troposphere in the future climate ...

Does Polar Warming Asymmetry Exist in Bathy‐Planet Experiments?
Abstract Ocean bathymetry and continental geometry shape ocean circulation, but whether these geographic constraints can sustain polar warming asymmetry in a fully coupled climate system remains unclear. Here we construct a fully coupled “bathy‐planet” configuration (BATHY), in which continental topography is removed and most land surfaces are replaced

A conditional analogue analysis of a severe thunderstorm disrupting Rome–Fiumicino Airport shows that, while synoptic circulation patterns remain largely unchanged since 1979, the thermodynamic environment has significantly warmed. Increased air and sea surface temperatures are linked to higher convective instability, precipitation, and wind shear ...

An initial investigation of the non-isotropic feature of GNSS tropospheric delay
Tropospheric delay is a significant error source in Global Navigation Satellite Systems (GNSS) positioning. Slant Path Delay (SPD) is commonly derived by multiplying Zenith Tropospheric Delay (ZTD) with a mapping function.

Tropospheric delay caused by spatiotemporal variations in pressure, temperature, and humidity in the lower troposphere remains one of the major challenges in Interferometric Synthetic Aperture Radar (InSAR) deformation monitoring applications.
