maging has much greater coverage and captures the cores of major fires, but its ability to constrain the height of the smoke plume is limited to those with discernible features. Noting that data from both imaging techniques can be combined to yield a better picture of smoke transport during a wildfire, Kahn et al. study the fires that occurred in the Alaska-Yukon region during the summer of 2004. The authors find that at least 10 percent of wildfire smoke plumes reached the free troposphere. Because accurate knowledge of smoke transport patterns can help scientists understand the environmental effects of wildfires, the combined strengths of stereo and lidar observations will help scientists better monitor potentially harmful smoke plumes.

8. Examining a link between the Suns upper atmosphere and Earth
To help scientists understand the energy budget of the Earths mesosphere and lower thermosphere, NASA launched the Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics (TIMED) satellite mission in December 2001. Instruments on TIMED, one of which observes and quantifies the energy budget by measuring the thermosPage: 1 2 3 4 5 6 7 8 9 10 11 12 13 Related biology news :1
