[Mesh] Wunderground

[John Atkeson]

BTW take a look at this map, use the scroll wheel to zoom out and in:

I asked the Wunderground people about this and according to them this data
is streamed directly to their servers, much of it via their
Weatherbridge/Meteobridge devices.

Every Weatherbridge box is a wifi router running OpenWRT.

I am going to press them a little further to estimate what percentage of
these points have actual Weatherbridges.  If the number looks good, I will
ask them if they've considered meshing.  The benefits should be obvious:
get unbroken data from hurricanes when the ISPs go down and from remote
places with no ISP coverage in the first place.

I don't know if their wifi is strong enough to cover the gaps, but weather
data is really low-bandwidth so perhaps repeating the same signal 1000+
times an hour could allow a lot of statistical noise removal.
