GNSS-IR Site Map

Icon for good sites
Good site - reflectometry works well and data is available
Icon for decommissioned sites
Decommissioned - reflectometry works well, data is available, but site is no longer operating
Icon for questionable sites
Questionable - reflectometry works sometimes or the signal is very weak probably due to location
Icon for bad sites
Bad - no data available at the site, either due to positioning of the sensor, lack of signal to noise ratio data, or data sampling is inadequate for the height of the sensor
