Description:Initial data from the Formosa Satellite ‐7/Constellation Observing System for Meteorology Ionosphere and Climate (FORMOSAT ‐7/COSMIC ‐2, hereafter C2), a recently launched equatorial constellation of six satellites carrying advanced radio occultation receivers, exhibit high signal ‐to‐noise ratio, precision, and accuracy, and the ability to provide high vertical resolution pro files of bending angles and refractivity, which contain information on temperature and water vapor in the challenging tropicalatmosphere. After an initial calibration/validation phase, over 100,000 soundings of bending angles and refractivity that passed quality control in October 2019 are compared with independent data, including radiosondes, model forecasts, and analyses. The comparisons show that C2 data meet expectations of highaccuracy, precision, and capability to detect superrefraction. When fully operational, the C2 satellites are
