GNSS-IR data for "Real-time water levels using GNSS-IR: a potential tool for flood monitoring"
Bibliographic record
Abstract
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).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
