[aprssig] Fwd: Help for First Responders

I haven't really monitored traffic other than that in the last few 
years.  Someone was talking about tracking a drone aircraft with a 
search light via APRS one year.  Mostly I try to take a break from work 
when I'm out there.

There's a fair amount of radio infrastructure out there year-round, up 
on a mountain and in the town of Gerlach.  I've thought about building 
some deployable weather stations with nephelometers to measure dust 
levels in real time.  It'd be interesting to put them at several 
locations around the site and generate an animation after the fact 
showing the dust storms blowing through.  They'd need to be rather 
high-range sensors, since the dust can get so bad you can't see three 
feet.  Building a nephelometer doesn't seem difficult but I don't know 
if I could keep the sensors clean enough to stay accurate.
