متن کاملPeriodic Correlation in Stratospheric Ozone Data
A fifty-year time series of monthly stratospheric ozone readings from Arosa, Switzerland is analyzed. The time series exhibits the properties of a periodically correlated (PC) random sequence with annual periodicities. Spectral properties of PC random sequences are reviewed and a test to detect periodic correlation is presented. An ARMA model with periodically varying coefficients (PARMA) is fi...
متن کاملStratospheric ozone and health.
BACKGROUND Stratospheric ozone is being depleted and ambient ultraviolet (UV) irradiance is probably increasing. While remedial steps have been taken through the Montreal protocols, at best it will take some 90 years for stratospheric ozone concentrations to return to the levels existing in the 1970s. METHODS The evidence that these changes may have harmful effects on health has been reviewed...
متن کاملStratospheric variability and tropospheric ozone
[1] Changes in the stratosphere-troposphere exchange (STE) of ozone over the last few decades have altered the tropospheric ozone abundance and are likely to continue doing so in the coming century as climate changes. Combining an updated linearized stratospheric ozone chemistry (Linoz v2) with parameterized polar stratospheric clouds (PSCs) chemistry, a 5-year (2001–2005) sequence of the Europ...
متن کاملStratospheric Ozone Depletion
There is now strong evidence that a consequence of human activities is the inadvertent accumulation of a variety of trace gases in the earth’s atmosphere. In the past decade, these global-scale changes in the chemical composition of the atmosphere have led to a very significant depletion of the stratospheric ozone layer over Antarctica in the southern spring months and also at northern latitude...
