	CLO Variations Over the Arctic [TOP]
	Catalytic Cycle of Polar Ozone Destruction: Chlorine reacts with ozone, forming chlorine monoxide (1-3), starting the catalytic ozone-destruction cycle. Chlorine monoxide can react with itself to form CI2O2 (4-5), which is broken apart by sunlight (6), producing chlorine atoms and an oxygen molecule (6-7). The cycle begins again as a chlorine atom reacts with more ozone (1). [TOP]
	Ascent of Tropical Water Vapor: (TOP) Deviations from the time-averaged HALOE water vapor measurements show the ascent of tropical air. Orange indicates moist air; blue and purple indicate dry air. (BOTTOM) Air enters the stratosphere through towering tropical cumulus clouds. During Northern Hemisphere summer, air entering the tropical stratosphere is slightly wetter (yellow) while during the Northern Hemisphere winter, air entering the stratosphere is slightly drier (blue).

	Mt. Pinatubo Erupting [TOP]
	Sulfur Dioxide From Mt. Pinatubo: Residual SO2 at 26 km measured by MLS on September 21, 1991, just over 3 months after the eruption of Mt. Pinatubo. [TOP]
	Global Time Series of Mt. Pinatubo Aerosol and the Decay of the Mt. Pinatubo Aerosol Cloud. [TOP]
	SUSIM/ACRIM [TOP]
	Variations in Solar UV as the Sun Rotates: A plot of the variation of the UV irradiance during rotation of the Sun as measured by SOLSTICE. The six solar images correspond to peaks and valleys of irradiance during the 27-day solar rotation. The bright regions on the solar images are the source of the peaks in UV radiation. [TOP]
