GNSS TEC

The dataset contains satellite observation files, ephemeris files, satellite clock error files, and differential code bias (DCB) files from approximately 40 stations in the Antarctic region between 2015 and 2016. And it contains uqrg ionospheric product data between 2015 and 2016. The above data are used to calculate the differential vertical electron content (dVTEC) between UPC TEC and GNSS TEC , which are further used to fit a model for correcting UPC products based on the spherical crown harmonic function.
