C. Satellite view of Asian dust near California

D. Satellite view of Asian dust over the Pacific

Click here or on image to enlarge. This April 15, 2001, NASA satellite image shows dust arriving in California from Asian deserts. Concentrations of dust are visible to the south, near the coastline (lower right of image); to the west the dust is mixed with clouds over open ocean. This dust event caused a persistent haze in places like Death Valley, California, where skies are usually crystal clear.

This NASA satellite image, taken on April 30, 2005, shows a plume of dust flowing from China to the north of the Korean Peninsula and over the Sea of Japan.The dust almost completely obscures the island of Honshu from satellite view. Such plumes can cross the Pacific and scatter dust across the Western United States.(NASA images created by Jesse Allen, Earth Observatory, using data obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Goddard Earth Sciences.

James Nolan, an aircraft mechanic at NCAR, works on a mount that will hold an instrument package on the fuselage of the NSF/NCAR Gulfstream-V. The instruments will help scientists measure solar radiation in the atmosphere. (Photo by Carlye Calvin, ©UCAR. News media terms of use*)

G. Hypothetical PACDEX flight map

Click here or on image to enlarge. This illustration shows a hypothetical plume and possible series of flight patterns during the PACDEX field project. When a major plume of dust and pollutants begins blowing off Asia, the G-V would fly from Boulder to Anchorage, where it would refuel, and then fly on to Yokota Air Base, Japan. It would then conduct a series of flights for about a week in and around the plume as the plume moves over the ocean to North America. (Illustration by Steve Deyo, ©UCAR. News media terms of use*)

H. Satellite measurements of Asian dust across the Pacific

Click here or on image to enlarge. This image, drawn from satellite observations, shows the movement of a particularly large dust plume from Asia to North America in 2001. The purple and blue areas represent no or little dust in the atmosphere; the yellow and orange areas represent a moderate to high amounts of dust. The image uses a scientific measure known as aerosol optical depth, which shows how much light in a column of the atmosphere is blocked by airborne particles. The observations were taken by the Moderate Resolution Imaging Spectroradiometer (MODIS), flown aboard NASA's Terra satellite. (Image courtesy NASA.)
