Radio Occultation Web Page Development

Abstract

This presentation was shared at the in-person conference of the 2025 CISESS Summer Internship Program held on 19 August 2025. The slides were presented by Leo Wang, an undergraduate student at the University of Maryland, and Emily Xinran Ma, a student at River Hill High School, under the mentorship of Xinjia Zhou (NOAA), Xi Shao (CISESS/UMD), and Guojun Gu (CISESS/UMD), and Yong Chen (NOAA). This presentation showcased the newly added features to the NOAA STAR Global Navigation Satellite System Radio Occultation (GNSS-RO) webpage. This included improvements to Integrated Calibration/Validation System (ICVS) page routing, multi-graph view functionality for ICVS pages, the addition of a monthly mean humidity anomaly page, and compiled product download statistics (such as user location, popular products, and downloads over time). The major feature highlighted was the creation of the Ground Tracker application, a web-based tool for plotting and interacting with large quantities of GNSS-RO profiles. The work done during this internship ensures that the Radio Occultation webpage remains a reliable source for accessing NOAA STAR GNSS-RO datasets and extends the page with new functionality to provide users with better tooling.
