vTEC data

Equivalent vertical TEC (vTEC) data have been obtained by receiver-independent exchange (RINEX) files containing GPS code and carrier phase observables acquired every 30 seconds by applying the Ciraolo et al. (J. Geodesy, 2007) method.
This dataset contains 8 1-year long time series of vTEC data for the following receiver-satellite pairs:
receiver GEONET 3009-satellite 15, receiver GEONET 0221-satellite 26, receiver SuGAr LHW2-satellite 32, receiver SuGAr-BNON satellite 32, receiver SuGAr LEWK-satellite 20, receiver SuGAr UMLH-satellite 32, receiver IGS AREQ00PER-satellite 20, receiver IGS IQQE00CHL-satellite 23.
Each file consists of eleven columns, from left to right:
column 1: year (YYYY)
column 2: month (MM)
column 3: day (DD)
column 4: time (hh:mm:ss)
column 5: satellite number
column 6: satellite azimuth (degree)
column 7: satellite elevation (degree)
column 8: geographic longitude (degree)
column 9: geographic latitude (degree)
column 10: sTEC (slant TEC, TECU)
column 11: vTEC (vertical TEC, TECU)
File names are [receiver name]_[year of observation].txt
