Research on Applicability of GNSS PWV Data in Northeast China and Its Application in Intelligent Precipitation Prediction

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract Atmospheric water vapor is an important factor in the formation and evolution of extreme weather events, such as heavy rainfall, typhoons, and major droughts and floods. We analyzed the applicability of precipitable water vapor (PWV) values from the Global Navigation Satellite System Meteorology (GNSS/MET) stations in northeastern China.

Zenith Tropospheric Delay Forecasting in the European Region Using the Informer–Long Short-Term Memory Networks Hybrid Prediction Model

Atmosphere
Zenith tropospheric delay (ZTD) is a significant atmospheric error that impacts the Global Navigation Satellite System (GNSS). Developing a high-precision, long-term forecasting model for ZTD can provide valuable insights into the overall trends of ...

A method for predicting short‐time changes in fine particulate matter (PM2.5) mass concentration based on the global navigation satellite system zenith tropospheric delay

Meteorological Applications, 2020
In this study, a method of haze prediction has been developed based on zenith tropospheric delay (ZTD). The relationship between ZTD and fine particulate matter (PM2.5, the main component of haze) during hazy periods in Beijing from 2015 to 2018 was ...

Active Diffusion Controlled Dual Stability in Thermoelectrics for Sustainable Heat Harvesting

Advanced Materials, Volume 37, Issue 38, September 25, 2025.
Introducing a Mg interlayer at the junction simultaneously stabilizes Mg3(Bi,Sb)2 materials and contacts for over 100 days. This dual stabilization derives from suppressing detrimental Mg diffusion and compensating for Mg loss, thereby maintaining an outstanding power density of 0.45 W cm−2 and remarkable conversion efficiency of 8.6% in aged modules ...

Analysis of the Synergistic Effect of Water Vapor, Thermodynamics, and Dynamics of the Heavy Rainfall Over Henan Province, China in July 2021

Meteorological Applications, Volume 32, Issue 5, September/October 2025.
In this study, a record‐breaking rainfall is analyzed based on the observation data and reanalysis data. The overlay of precipitation provided by both dynamic delivery from the southeast and cloud microphysical production over Zhengzhou was the main cause of the rainfall under the background of an atypical weak environmental field. ABSTRACT During July

Riverine Isoscapes Modeling in the Yangtze River Basin, China: Insights Into Basin Processes and Source‐Water Contributions

Water Resources Research, Volume 61, Issue 9, September 2025.
Abstract The utilization of surface water isoscapes facilitates the characterization of source‐water contributions and hydrological processes within a basin. However, intricate river network topology poses significant challenges in applying this approach to large and complex basins.
