Dear colleagues, I am very pleased to inform you that the STAR-processed (with a 90-120 minutes latency, although released daily for now) NOAA commercial RO (i.e., PlanetiQ and Spire since Jan. 2025) is available from https://gpsmet.umd.edu/gnssro/download_star_nrt.php We are still refining our quality controls, excess phase processing, and improving our GNSS POD prediction algorithm. In general, these results demonstrate that the STAR-processed results are consistent with those from the references (ECMWF forecast and UCAR's results). We also added a function to track users and data downloads(for all the STAR data) on https://gpsmet.umd.edu/gnssro/download_stats.php. We are pleased to have had at least 1,600 individual users download around 42 TB in the past two months. Any feedback, suggestions, and questions on these data and other STAR-processed data are welcome (shu-peng.ho@noaa.gov and xi.shao@noaa.gov).
