Synopsis |
| NASA SATELLITES AND BALLOONS SPOT AIRBORNE POLLUTION TRAIN | G04-023 | 5/3/04 | 7:33 | NASA scientists, using multiple satellites and balloon-borne sensors, have discovered that pollution can catch an airborne "express train," or wind current, from Asia all the way to the southern Atlantic Ocean.
Scientists believe during certain seasons, as much as half of the ozone pollution above the Atlantic Ocean may be speeding down a "train" track of air from the Indian Ocean. As it rolls along, it picks up more smog from air peppered with thunderstorms that bring it up from the Earth's surface.

TAPE CONTENTS: |
| ITEM (1): Long Range Pollution Transport (G01-024) - Man-made pollution from Asia can flow southward, get caught up into clouds, and then move steadily and rapidly westward across Africa and the Atlantic, reaching as far as Brazil. This sequence combines model and satellite data to show how carbon monoxide moves around the world. The MOPITT (Measurements of Pollution in the Troposphere) instrument on board the Terra satellite provided data for this sequence.

| ITEM (2): Ozone and Smoke Over The Indian Ocean (G01-044) - Researchers have discovered that smoke and smog move in different ways through the atmosphere. A series of unusual events several years ago created a blanket of pollution over the Indian Ocean. In this animation, significant smog or tropospheric ozone is represented by red and green and regions of significant smoke index are in shades of white and gray. NASA's Earth Probe TOMS (Total Ozone Mapping Spectrometer) satellite instrument provided the data for this sequence. Courtesy: NASA

| ITEM (3): Asian Brown Cloud (G03-008) - This NASA satellite image shows a dense blanket of polluted air over central eastern China -- dense enough that the coastline around Shanghai virtually disappears. The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) on board the Orbview 2 satellite captured this image January 10, 2003.

| ITEM (4): Bay of Bengal (G02-075) - These images of the Bay of Bengal was taken by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) onboard the Orb View-2 satellite on March 23, 1999.
