Radiation Comparison Before and After 9-11
From NASA My NASA Data
Several research studies have suggested that contrails (condensation trails from aircraft) can alter the radiative budget of the Earth by increasing the cloud cover at high altitudes. The tragic events of September 11, 2001, caused virtually all air traffic to be grounded over the US for nearly three days. The absence of contrails over the United States during this time gave scientists a unique opportunity to test this theory. In this lesson, students will read some scientific papers related to these studies and draw their own conclusions using appropriate data from the MY NASA DATA Live Access Server (LAS). Daily satellite data or three-day average data for cloud cover, temperature and radiation parameters are available in the LAS for inquiry.
