Has pollen got you sneezing? Wondering what's causing that mysterious afternoon haze? How do you find out what's in the air you are breathing? For the thousands of people who visit the University of Maryland Baltimore County's "Smog Blog" each day, the answer is just a web click away. The Smog Bloggers combine laser measurements of current air quality with NASA satellite data to paint a daily picture of air pollution across the US. To date, the blog has received over two million hits, and is itself a big hit with weather forecasters, astronomers, asthma sufferers, and those with just a healthy curiosity about what kinds of pollution they may be breathing in.

NASA's launching a new mission this summer designed to better understand air pollution and gather data that could allow pollutants to be monitored more exactly from space. The field study coined, "Discover-AQ", will take place over the Baltimore/DC region on select days in July. ||

Dr. Bryan N. Duncan is a deputy project scientist for the Aura Mission at NASA Goddard. In this talk he tells the story of air quality in three cities-Beijing, Los Angeles, and Atlanta.For complete transcript, click here. || G2015-017_Air_Quality_TedTalk_nasaportal_print.jpg (1024x576) [74.5 KB] || G2015-017_Air_Quality_TedTalk_nasaportal_searchweb.png (320x180) [63.8 KB] || G2015-017_Air_Quality_TedTalk_nasaportal_print_thm.png (80x40) [6.7 KB] || G2015-017_Air_Quality_TedTalk_appletv.webm (960x540) [100.6 MB] || G2015-017_Air_Quality_TedTalk_appletv.m4v (960x540) [323.4 MB] || G2015-017_Air_Quality_TedTalk_youtube_hq.mov (1280x720) [416.3 MB] || G2015-017_Air_Quality_TedTalk_1280x720.wmv (1280x720) [342.1 MB] || G2015-017_Air_Quality_TedTalk_prores.mov (1280x720) [13.8 GB] || G2015-017_Air_Quality_TedTalk_appletv_subtitles.m4v (960x540) [323.0 MB] || G2015-017_Air_Quality_TedTalk_ipod_lg.m4v (640x360) [135.3 MB] || G2015-017_Air_Quality_TedTalk_nasaportal.mov (640x360) [290.3 MB] || TedTalk_AirQuality.en_US.srt [18.0 KB] || G2015-017_Air_Quality_TedTalk_ipod_sm.mp4 (320x240) [60.7 MB] ||

The ATom mission aboard NASA's DC-8 flying laboratory is sampling world-wide in one of the most extensive surveys of the atmosphere to date, measuring over 200 gases as well as airborne particles. The science team is particularly interested in methane, tropospheric ozone and black carbon particles, which have strong effects on climate and which all have both human and natural origins.Below are interviews with four scientists participating in the research flights:* Donald Blake, UC Irvine* Róisín Commane, Harvard University* Tom Ryerson, NOAA* Jack Dibbs, University of New HampshireFollow along with all eight of our #EarthExpeditions here: http://www.nasa.gov/earthexpeditions ||
