HIRDLS Cloud Extinction

HIRDLS Cloud Extinction

High thin clouds are difficult to detect from space. The first comprehensive climatology of thin clouds has been developed with the HIRDLS limb viewing infrared radiometer.

OMI Observes Impact from the Gulf Hurricanes

OMI Observes Impact from the Gulf Hurricanes

Hurricanes Katrina and Rita caused a significant reduction in nitrogen dioxide emissions.

Nitrogen dioxide in California

Aggressive air quality regulations of emission reductions show results in Aura's OMI imagery.

Sarychev Peak eruption

Sarychev Peak Eruption

The eruption of Sarychev Peak (Kurile Islands) in mid-June 2009 produced a large stratospheric sulfur dioxide cloud that spread rapidly eastward in strong jet stream winds.
