Advanced GNSS Remote Sensing Techniques for Meteorology and Climate Sciences

Dear Colleagues,

In recent years, severe weather events and climate change have seriously endangered the safety of human lives and assets. Effective monitoring and accurate forecasting of these phenomena are of great significance for disaster prevention and mitigation. With the rapid development of the cutting-edge multi-GNSS systems, GNSS remote sensing techniques offer an unprecedented opportunity for atmospheric modeling and provides high accuracy mega-geodetic data for meteorological and climatological studies. Precipitable water vapor, zenith total delay, slant total delay, slant water vapor, gradient, bending angle, refractivity and other atmospheric products obtained from space/ground-based GNSS remote sensing techniques have heralded a new era of atmospheric sounding, space weather monitoring, GNSS meteorology and climatology. To take advantage of the advanced GNSS remote sensing technique, this Special Issue mainly focuses on papers that address topics including but not limited to:

• Advanced multi-GNSS atmospheric sounding and data processing;
• Atmospheric augmentation modeling for PPP;
• Data assimilation into operational earth system models;
• Space weather modeling and monitoring;
• Data mining of atmospheric products;
• Machine learning-based approaches for data retrieval, weather forecasting and climate monitoring.
• Furthermore, miscellaneous interdisciplinary researches and new applications in the atmosphere, meteorology and climatology fields are also welcomed.
