weather systems: detecting temperature, humidity, and smoke. 105 Increased fire byproducts in the troposphere can increase ozone concentration beyond safe levels. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants 420 million years ago. 8 Such places include the vegetated areas of Australia and Southeast Asia, the veld in southern Africa, the fynbos in the Western Cape of South Africa, the forested areas of the United States and Canada, and the Mediterranean Basin.

Contents, history edit, australia edit, wildland fire, known in Australia as bush fire, has played a major role in Australia due to arid conditions. Additional capabilities such as night vision, brightness detection, and color change detection may also be incorporated into sensor arrays. Symptoms of these complications include wheezing and shortness of breath and cardiovascular symptoms include chest pain, rapid heart rate and fatigue. Sierra Nevada Ecosystem Project: Final report to Congress, vol. 101 Computer-aided models such as calpuff may help predict the size and direction of wildfire-generated smoke plumes by using atmospheric dispersion modeling.
