FY-3E GNOS-II GNSS-R Data for "First Operational Spaceborne GNSS Reflectometry with Galileo Signals: Measurements, Calibration and Wind Speed Retrieval"

This dataset includes FY-3E GNOS-II GNSS-R Data for paper "First Operational Spaceborne GNSS Reflectometry with Galileo Signals: Measurements, Calibration and Wind Speed Retrieval" submitted to Geophysical Research Letters.The L1 data including DDMs are in the file L1_20220706_0321.zip. They are in HDF format.The L2 data including observables and retrieved winds are in the file process_data_2022_0701_0731.mat and process_data_2022_0801_0831.mat. The two months data are grouped into two files in MATLAB format.
