HALOE Measurements of HCl in the Stratosphere (1992 - 1998)

Visualizations by Barbara Summey Released on April 9, 1999

HALOE was designed to carefully monitor hydrogen fluoride and hydrogen chloride, byproducts of CFC destruction in the stratosphere. HALOE operates by observing the absorption of infrared radiation by these molecules against the rising and setting sun. When UARS was first launched, measurements by HALOE showed that CFC byproducts were still increasing in the stratosphere. But the newest HALOE measurements now show that CFC by-products are no longer increasing. UARS has shown that the stratosphere is starting to respond to the international ban on CFC manufacture.
