Instrument-laden aircraft are surveying the Colorado high country this month as scientists search for better ways to measure how much water is locked up in the world's mountain snows -- water that sustains a substantial share of the global population.A NASA-led experiment called SnowEx is using five aircraft to test 10 sensors that might one day be used to monitor snow from satellites. The global average is 30 percent of snow depth, Kim said -- 10 inches of snow melts down to 3 inches of water.Four sensors will measure snow density: three other types of radar, plus a passive microwave instrument, which detects how much of the Earth's natural microwave radiation the snow is blocking.A hyperspectral imager and a multispectral imager will measure how much sunlight the snow is reflecting, which helps determine how fast it will melt.One key technology used to predict snow runoff in the American West is the Snow Telemetry Network, or SNOTEL, operated by the U.S. Department of Agriculture's Natural Resources Conservation Service.
