Ozone trends, derived from 1979–1996 Dobson spectrophotometer total ozone data obtained at five U.S. mainland midlatitude stations, averaged −3.4, −4.9, −2.6, −1.9, and −3.3%/decade for winter, spring, summer, and autumn months, and on an

During two days in late December 1994, total ozone measured at the Mauna Loa Observatory on the island of Hawaii, dropped below 200 Dobson Units (DU) for the first time since ozone measurements began at this site over 30 years ago. Total ozone values

Continuous surface ozone measurements have been made at Mauna Loa Observatory (MLO) for 20 years. In addition, weekly ozone profile measurements using balloonborne ozonesondes have been carried out from Hilo, Hawaii, since 1985. These long-term recor

Total ozone levels, which were 10–15% below normal over the U.S. during the winter of 1992–1993, returned to levels slightly above normal during the winter of 1993–1994. Investigation of ozone vertical profiles indicates that in the region wher

Dobson spectrophotometer observations conducted since the early-to-mid 1960s at Bismarck, North Dakota; Caribou, Maine; Boulder, Colorado; Wallops Island, Virginia; Nashville, Tennessee; and at Fresno, California, since 1983, have revealed record low

Ozone profiles obtained at Boulder, Colorado and Wallops Island, Virginia indicate that ozone was about 25% below normal during the winter and spring of 1992-93 in the 12-22 km region. This large ozone reduction in the lower stratosphere, though some

Ozonesonde measurements at Hilo, Hawaii (20°N), after the eruption of Pinatubo in June 1991, are compared to measurements made there from 1985 to 1990 in order to investigate possible volcanic effects. The general nature of the ozone anomalies in 19

A significant negative correlation exists between June–August sea surface temperatures (SSTs) in the eastern equatorial Pacific and 15–31 October total ozone values at South Pole, Antarctica. SSTs in the eastern equatorial Pacific were anomalousl
This report describes work to improve the quality of total ozone and Umkehr data obtained in the past at the NOAA Climate Monitoring and Diagnostics Laboratory and the Dobson spectrophotometer ozone observatories. The authors present results of total

A historical overview is presented of Dobson spectrophotometer total ozone observations made by the U.S.A.'s National Oceanic and Atmospheric Administration (NOAA) since the early 1960s. NOAA's contributions in upgrading the quality of total ozone me
