Abstract

Ground Instruments Verify Ozone Data Budget Experiment (ERBE) satellite, confirms that from Satellites clouds result in a net cooling of the earth. Previously, A network of ground-based instruments used in mon- atmospheric scientists were divided on the impact of itoring stratospheric ozone is being put to work to clouds on the earth's temperature. verify data from satellites that provide continuous These measurements serve as the base line for ozone readings. climate modelers to determine whether clouds will According to the National Oceanic and Atmo- partially offset or enhance a future warming of the spheric Administration (NOAA), Dobson ultraviolet earth due to the greenhouse effect. The greenhouse spectrometers at five sites around the Northern Hem- effect is the warming of the earth's atmosphere and isphere are providing ozone-layer measurements for surface from increased concentrations of gases, such comparison with readings from solar backscatter ul- as carbon dioxide, methane, nitrous oxide, and chlo- traviolet (SBUV) instruments on the satellites. rofluorocarbons.
