000007015 520__ $$aThe European Plate Observing System (EPOS) is a European research e-infrastructure that aims to enhance the integration, accessibility, and utilization of multi-disciplinary datasets and services related to the Solid Earth sciences. EPOS’ GNSS (Global Navigation Satellite Systems) component, through the EPOS-GNSS Data Gateway, provides access to daily GNSS RINEX data from a distributed infrastructure of twelve data nodes. In this poster, we introduce a new community web portal (https://gnssquality-epos.oma.be) and alert systems developed by the Royal Observatory of Belgium to provide the necessary information for monitoring the availability and quality of daily GNSS observation data that are discoverable through EPOS. Currently, the web portal displays the tracking performance plots of more than 1700 EPOS-GNSS stations. The plots focus on several GNSS data quality indicators (DQIs), such as the number of observed versus expected observations, the number of missing epochs, the number of observed satellites, the maximum number of observations, the number of cycle slips, the Standard Point Positioning (SPP) results, and the multipath values on code observations. This unique set of DQIs is provided in the web portal to give helpful information that can be used to detect a potential degradation of the quality of the GNSS observations. Here we will present the web portal, the considered data quality indicators, and its usage for GNSS data analysis in geophysical applications.
