eSWua IONORING tool: sTEC computation
Last modified at Sep 5th, 2023, 11:00 GMT
Description
The sTEC is derived from the code observables on L1 and L2 frequencies. The calibration of the sTEC is obtained by using the method described by Ciraolo et al., 2007 [1], which evaluated the “differential code biases” (DCBs) for each station-satellite arc by exploiting a combination of code and phase observables. Although this calibration technique is robust and widely used, especially for mid-latitude and low-latitude studies, it has the intrinsic limitation of not being operating in real-time. This is because it assumes the availability of complete arcs of observations. To overcome this limitation and for the purposes of the real-time operation, the DCBs are evaluated for each station-satellite couple and for a given day by computing its mean value on the previous 3 days.
