Scientists Propose Satellite Early Warning System For Forest Fires 91
Hugh Pickens DOT Com writes "As firefighters emerge from another record wildfire season in the Western United States, Robert Sanders reports at the UC Berkeley News Center that scientists have designed a satellite using state-of-the-art sensors, that could view the Western US almost continuously, snapping pictures of the ground every few seconds searching for small hot spots (12 m2) that could be newly ignited wildfires. Firefighting resources could then be directed to these spots in hopes of preventing the fires from growing out of control and threatening lives and property. "If we had information on the location of fires when they were smaller, then we could take appropriate actions quicker and more easily, including preparing for evacuation," says fire expert Scott Stephens. Fire detection today is much like it was 200 years ago, relying primarily on spotters in fire towers or on the ground and on reports from members of the public. This information is augmented by aerial reconnaissance and lightning detectors that steer firefighters to ground strikes, which are one of the most common wildfire sparks. But satellite technology, remote sensing and computing have advanced to the stage where it's now possible to orbit a geostationary satellite that can reliably distinguish small, but spreading, wildfires with few false alarms. Carl Pennypacker estimates that the satellite, which could be built and operated by the federal government, would cost several hundred million dollars – a fraction of the nation's $2.5 billion yearly firefighting budget. "With a satellite like this, we will have a good chance of seeing something from orbit before it becomes an Oakland fire," says Pennypacker. "It could pay for itself in one firefighting season.""

Every GPS satellite has automatic nuclear-detonation detectors [fas.org] built in. Just turn the sensitivity up a little bit, and presto! A global forest fire detection system.

i bet there's some existing satellites with even better resolution and heat detection capabilities than that... but they're off-limits to the national park service and other forest/wildlife agencies......

It's supposed to burn.
Don't turn this simple, natural reality into a problem by preventing fires until you have a giant pile of fuel that inevitably erupts into a biblical disaster.
Since it's supposed to burn, we don't need early detection to make putting it out easier. So put away the satellites; the Department of the Interior can just not expand by another $63 kabillion in the name of "fighting" forest fires with a space program so they can "respond" to the site of some hapless rural leaf burner with a squad of jack-booted enviro-thugs.
Sorry if your vision of the perfect home is a mountain mcmasion embedded in a sylvan paradise. That's just how it is here on Earth where wood eventually burns. Clear the perimeter or risk losing it to the next natural and necessary forest fire.
"They" won't let you clear the perimeter to protect your property? Enviro-statists suck; stop voting for them. "They" banned controlled burns and other forest management? Enviro-statists suck; stop voting for them.

NOBODY, especially environmentalists, have "banned controlled burns" anywhere on the planet, that's just some lunatic tea party bullshit that makes your puny brain feel good about itself. In fact over here "environmentalists" have been instrumental in getting the experience of 40kyrs of native fire control practice recognised and at least three states now employ natives to teach and practice it.

Seems to me your the only one who wants to "kick heads". And really, what the fuck has bushfire control got to do with someone burning a pile of leaves in their yard?

I can see both sides of a controlled burn. Yes, it is probably the right thing to do. But the first time it got out of control and burned a bunch of houses down, the crap would hit the fan. Can you imagine the news footage of the people who's houses were burned down by a fire set intentionally by the government.
Colorado residents do not have to imagine this; we lived it this year. Homes destroyed, people dead, because the state forest service ignored its own guidelines for setting and monitoring controlled burns.
Hint: you defer the controlled burn when winds are predicted to be gusting to 60-80 m/h in the days after the burn.
Hint: when guidelines call for you to have personnel monitoring the burn site for a certain period afterward, you have the people up there at least most of the time; you do not leave it unattended for days.
Hint: when guidelines call for the personnel you send to take a source of water (in other words, small tank truck) with them, you do not send two guys in a pickup with shovels.
Hint: when guidelines say it is time to call in an emergency, and there's no phone or radio service, the two guys should abandon their shovels long enough to get to where they can call, rather than continuing to beat at individual hot spots in a gradually losing race until the thing explodes.
Whether or not they learned these lessons, we do not know, because of course the bureaucrats went into full-on defensive mode and refused to admit error, refused to out who it was that made the catastrophic decisions, and so on.

Actually, over here, the US Forest Service pursued a policy of 100% fire suppression, never letting anything burn if they could stop it, for 50 fucking years. Whether or not environmentalists had any role in this, I do not know. But environmentalists have had a significant role in blocking the type of selective logging, "patch clear-cutting", which is what we need to reduce the danger and start to restore a healthy balance in western forests.
So, I'm glad that your environmentalists have played such a role in your country. But that doesn't mean ours are not idiots, and in fact on this subject most of ours are uninformed idiots.

Assumption #1; fires started by lightning would presumably have some form of cloud cover (lightning point of origin), would this obscure the view of a 10mx10m fire until after it has become large enough to be dangerous?
Is it common to have lightning without clouds? I'm trying to think if I recall ever seeing lightning out of a clear sky.
I live in Victoria (Australia) and remember the Ash Wednesday bushfires from a first hand - sitting on the beach watching it come down the hill because we were cut off before the evacuation call went out - point of view. As such, I have an interest in anything that gives an early warning.
