Ozone-depleting gases in the atmosphere: will they continue to decline?
Article Abstract:
A reseach conducted by the National Oceanic and Atmospheric Administration (NOAA) reveals an overall decline of ozone-depleting substances in the atmosphere for the past five years. Such decline can be attributed to the lessening in the atmosphere of a single chemical, methyl chloroform. The study suggests that further reductions in the threat to the ozone layer would have to come from reductions in other ozone-depleting gases since the rapid natural disintegration property of methyl chloroform would only make them a much smaller part of the existing ozone-depleting substances.

Contract awarded for ozone instrument for satellite system of the future
Article Abstract:
Commerce Sec William M. Daley announced the awarding of a $91 million contract to Ball Aerospace and Technologies Corp to create a suite of satellite instruments. The contract, which was awarded on May 14, 1999, calls for the design and fabrication of the Ozone Mapping and Profiler Suite which will substantially enhance the accuracy of earth's ozone measurements. Daley reveals that contract will be followed by others later in 1999 or in the year 2000 to create a series of satellite instruments that will enhance short-term weather forecasts and long-term climate prediction.
