GNSS-IR data for "Real-time water levels using GNSS-IR: a potential tool for flood monitoring"

Organised SNR data used for GNSS-IR analysis in the article "Real-time water levels using GNSS-IR: a potential tool for flood monitoring" by David Purnell, Natalya Gomez, William Minarik and Gregory Langston. Data is organised by sites:<br> 'rv3x' is Trois-Rivières<br> 'sjrx' is Saint-Joseph-de-la-Rive<br> The 'x' at the end signifies that there is data from multiple co-located antennas at these sites (see details about naming format below**) SNR data is given as text files in the format specified here:<br> https://gnssrefl.readthedocs.io/en/latest/pages/file_structure.html#the-snr-data-format<br> Each line is coded in Python using:<br> "{0:3.0f} {1:10.4f} {2:10.4f} {3:10.0f} {4:7.2f} {5:7.2f} {6:7.2f} {7:7.2f} {8:7.2f} \n".format(sat, elv, azi, sod, 0, 0, snr, 0, 0)<br> where 'sat' is the satellite PRN identifier, with an offset such that GLONASS satellites are between 100-200 and Galileo are between 200-300<br> elv is satellite elevation (degrees)<br> azi is satellite azimuth (degrees)<br> sod is seconds of day<br> snr is L1 SNR The key difference from the gnssrefl snr data format is the naming of the files.<br> Each file is of the format:<br> sssxYYMMDDHH.snr<br> **where sssx is the station ID ('sjr' or 'rv3') + the letter a, b, c or d to indicate the four co-located antennas<br> For example,<br> 'rv3a20090917.snr' comprises of data from antenna 'a' at Trois-Rivières on 9th September 2020 at 17h (UTC)<br> 'sjrd21111302.snr' comprises of data from antenna 'd' at Saint-Joseph-de-la-Rive on 13th November 2021 at 02h (UTC)<br> Each file contains one hour of data (as opposed to 24 hours in the gnssrefl format).
