TOMS cloudy ozone anomaly
This study investigates anomalous ozone distributions over cloudy areas in Nimbus-7 (N7) and Earth-Probe (EP) TOMS version-7 data and analyzes the causes for ozone anomaly formation. A 5 •-longitude by 5 •-latitude region is defined to contain a Positive Ozone Anomaly (POA) or Negative Ozone Anomaly (NOA) if the correlation coefficient 5 between total ozone and reflectivity is ≥0.5 or ≤−0.5. Th...

متن کاملConcentrations of Tropospheric Ozone from 1979 to 1992 over Tropical Pacific South America from TOMS Data
An estimate of tropospheric ozone concentrations was obtained from the difference in the Total Ozone Mapping Spectrometer (TOMS) data between the high Andes and the Pacific Ocean. From 1979 to 1992 the tropospheric ozone concentration apparently increased by 1.48 ± 0.40 percent per year or 0.21 ± 0.06 Dobson unit per year over South America and the surrounding oceans. An increase ...

متن کاملLong-term ozone exposure and mortality.
BACKGROUND Although many studies have linked elevations in tropospheric ozone to adverse health outcomes, the effect of long-term exposure to ozone on air pollution-related mortality remains uncertain. We examined the potential contribution of exposure to ozone to the risk of death from cardiopulmonary causes and specifically to death from respiratory causes. METHODS Data from the study cohor...
