. >> brett butler is the lead researcher on the fire safety zone project. he's based at the rocky mountain research center in missoula a, montana. this is the hard data that you guys bring in from the field. >> yes. >> what is the end goal of this? >> the end goal of this is to help us to design simulations but we didn't know until we set this parameter. how hot does the fire need to be? these measurements help us so we are accurately simulating what's happening in real conditions. >> led by the u.s. forest service, they are committed to understanding fire behavior through countless controlled burns and deployments, new safety models and tools are constantly being created. >> so in theory, that little circuit board on the front of on. >> this test is to improve the sensors on the fireproof cameras that recorded these dramatic images the burn. >> we need more measure in the meantime, slope and wind. >> that's difficult because there are safety issues. we have to get out in front of the fire, put this equipment out and then walk away, but naturally, it's dang
