b. Analyze atoms and molecules of elements in meteorites
c. Find amount of pollution in remote corners of Earth
d. None of the above

ANSWER: Find amount of pollution in remote corners of Earth
 
  • NASA is launching an airborne mission that will map the contours of the Earth’s atmosphere to discover how much pollution exists in the most remote corners of the planet and assess how the environment has changed as a result.
  • Pollutants emitted to the atmosphere are dispersed over the whole globe, but remote regions are cleaner, by factors of 1,000 or more, than areas near the continents, researchers said.
  • The Atmospheric Tomography (ATom) mission is the first to survey the atmosphere over the oceans.
  • ATom is particularly interested in methane, ozone and airborne particles called black carbon, which have strong effects on climate and which all have both human and natural origins.
