Evaluation of Marine Boundary Layer Clouds Over the Northeast Pacific During the CSET Campaign in E3SM Version 2

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 19, 16 October 2025.
Abstract It is still challenging to reproduce marine boundary layer (MBL) clouds well in large‐scale models despite their importance to the Earth's radiation budget and hydrological cycle. This study evaluates representation of the MBL and clouds in the Energy Exascale Earth System Model (E3SM) version 2. This study compares the E3SM simulation results

Flower‐Type Organized Trade‐Wind Cumulus: A Multi‐Day Lagrangian Large Eddy Simulation Intercomparison Study

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.
Abstract Shallow cumulus cloud fields in subtropical marine trade wind environments, particularly over the tropical Atlantic Ocean, show distinct organizational patterns. Among these, Flower‐type clouds are characterized by expansive stratiform cloud patches surrounded by regions of scattered convection.

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.

Retrieval of Real-Time Zenith Tropospheric Delay with Beidou PPP-B2b

, 2023
The traditional method for retrieving the real-time zenith total delay (ZTD) with GNSS requires stable access to the internet for the reception of satellite orbit and clock corrections. This limits the use of this technique in areas without a reliable internet connection. The new precise point positioning service via the B2b signal (PPP-B2b) service on

Accuracy Assessment and Rainfall Intensity Response Mechanisms in GNSS Real‐Time PPP Water Vapor Retrieval: Coupling Effects of Multi‐Source Real‐Time Products and Meteorological Conditions

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract The Global Navigation Satellite System (GNSS) real‐time Precise Point Positioning (PPP) technology offers a highly efficient approach for atmospheric Precipitable Water Vapor (PWV) monitoring and extreme weather warning. However, its retrieval accuracy is limited by the performance of orbit and clock products, as well as the coupling effects ...

The VMD-Informer-BiLSTM-EAA Hybrid Model for Predicting Zenith Tropospheric Delay

Remote Sensing
Zenith Tropospheric Delay (ZTD) is a significant source of atmospheric error in the Global Navigation Satellite System (GNSS). Developing a high-accuracy ZTD prediction model is essential for both GNSS positioning and GNSS meteorology.
