Data from NASAs Terra satellite is adding to our understanding of how pollution spreads around the globe. The information will help scientists protect and understand the Earth.
Pollution Outflow from Spring 2003 Fires in Siberia
In the spring of 2003 there were large numbers of fires in Siberia, especially in the Baikal region. These were detected by the MODIS instrument on the Terra satellite (top). This graphic shows the number of fires detected during the month of May, 2003. These fires produced large amounts of fine carbon aerosol which spread out over the Pacific Ocean (center). The suspended particles, also detected by MODIS, only last for a few days. The MOPITT instrument on the Terra satellite measures carbon monoxide gas (CO). CO was also produced by the fires (bottom). This pollutant can last for over a month. The longer lifetime allows the gas to cross the Pacific Ocean and reduce air quality over North America before continuing on around the globe.

NASA funded scientists from the National Center for Atmospheric Research (NCAR), Boulder, Colo., will present two studies focusing on global air pollution. Their presentations are part of the 2004 Joint Assembly of the American and Canadian Geophysical Unions.
David Edwards will discuss "Observations of Carbon Monoxide and Aerosol from the Terra Satellite: Northern Hemisphere Variability," on Thursday at 8:45 a.m. EDT in room 520D of the Palais des Congrès, Montreal. Cathy Clerbaux will discuss, "Tracking of Pollution Plumes Using Measurements of Pollution in the Troposphere (MOPITT) Measurements," at 9:30 a.m. EDT.

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
