![Icon for good sites](/graphics/icons/markers/mm_20_white.png)
- Good site - reflectometry works well and data are available
![Icon for decommissioned sites](/graphics/icons/markers/mm_20_yellow.png)
- Decommissioned - reflectometry works well, data are available, but site is no longer operating
![Icon for questionable sites](/graphics/icons/markers/mm_20_red.png)
- Questionable - reflectometry works sometimes or the signal is very weak probably due to location
![Icon for bad sites](/graphics/icons/markers/mm_20_black.png)
- 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
