Then it rained
The last 7 days have showed poor link quality of mesh between regular nodes and improved distant nodes links. It has been very trying week. In previous blogs the RF signal quality has been poor. But at the same time I seen nodes link together and signal strength between nodes that do not have a line of site.
What I am observering is reflection and refraction of the RF signal from the atmosphere due to pollution, humidity and temperature over 30C.
As it was getting hotter we had a thunderstorms with heavy rain that washed away most of the pollution and humidity.
What happen was the mesh node links improved again and the distance reflected links were once again lost.
Extreme conditions have illustrated that RF signal is affected by weather conditions.

Hmm, I wonder whether the weather alone is the full story...
In East Yorkshire, UK I have seen amazing Non-LOS node linkage in the last week or so that has faded just today.
Whilst this is a GOOD THING wrt routing stability for what is a largely fixed wireless network, it does make me wonder if there are hemispheric factors at play rather than simply local climatic conditions.
Perhaps as simple as it being the Northern Summer in both Canada and the UK, hence we see similar RF behaviour... or maybe just coincidence... mesh magic I reckon :)
it would be interesting to hear whether any Southern folk (eg Aus or NZ) also experienced the same pattern during the same timeframe

Hi Guy
Yes we are getting a lot of skip. I really thought it has something to do with the high amount of smog we are getting.
Northern Lights actually disrupt communications.
But you are right we should get someone from NZ or Australia to observe.
