Improving Sentinel‐3 Altimetry Data With GPD+ Wet Tropospheric Corrections

Earth and Space Science, Volume 11, Issue 8, August 2024.
Abstract The provision of accurate wet tropospheric corrections (WTC), accounting for the delay of the radar pulses caused mostly by the atmospheric water vapor in the altimeter‐range observations, is pivotal for the full exploitation of altimeter‐derived surface heights.

Evaluate the Impact of Regional Ionospheric Data Assimilation Model on Precise Point Positioning

Space Weather, Volume 22, Issue 8, August 2024.
Abstract This study presents an innovative approach to improving the accuracy and reducing the error convergence time of static Precise Point Positioning (PPP) in Global Positioning System (GPS) navigation. The research focuses on the impact of the high spatial and temporal resolution of a regional ionospheric data assimilation model on PPP over Taiwan.

CERRA, the Copernicus European Regional Reanalysis system

Quarterly Journal of the Royal Meteorological Society, Volume 150, Issue 763, Page 3385-3411, July 2024 Part B.
A high‐resolution, 5.5 km, regional reanalysis has been produced for a domain covering the whole of Europe from 1984 to 2021 together with a 10‐member ensemble run at 11‐km resolution as well as an offline surface analysis. The reanalyses and re‐forecasts from CERRA show an added value compared to the global reanalyses for almost all variables at the ...

The Performance of Different Mapping Functions and Gradient Models in the Determination of Slant Tropospheric Delay

Remote Sensing, 2020
Global navigation satellite systems (GNSSs) have become an important tool for remotely sensing water vapor in the atmosphere. In GNSS data processing, mapping functions and gradient models are needed to map the zenith tropospheric delay (ZTD) to the ...

Determination of high-precision tropospheric delays using crowdsourced smartphone GNSS data [PDF]

Atmospheric Measurement Techniques
The Global Navigation Satellite System (GNSS) is a key asset for tropospheric monitoring. Currently, GNSS meteorology relies primarily on geodetic-grade stations. However, such stations are too costly to be densely deployed, which limits the contribution
