Occurrence of ozone anomalies over cloudy areas in TOMS version-7 level-2 data
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. The ...

متن کاملTropical tropospheric ozone derived using Clear-Cloudy Pairs (CCP) of TOMS measurements
Using TOMS total-ozone measurements over high-altitude cloud locations and nearby paired clear locations, we describe the Clear-Cloudy Pairs (CCP) method for deriving tropical tropospheric ozone. The high-altitude clouds are identified by measured 380 nm reflectivities greater than 80% and Temperature Humidity InfraRed (THIR) measured cloud-top pressures less than 200 hPa. To account for locati...

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 ...
