The ClO amounts in the atmosphere are \nretrieved from remote measurements of microwave emission spectra. ClO column densities of up to about 2.5 \u00d7 \n1015 cm-2\n are recorded during September, when chlorine is present in chemically active forms due to reactions on \nthe surface of Polar Stratospheric Cloud (PSC) particles. Maximum mixing ratios of ClO are approximately 2 \nppbv. The annual average of ClO column density during the activation period is anticorrelated with similar \naverages of ozone column measured at nearby Arrival Heights, with correlation coefficient of \u20130.81, and with \naverages of ozone mass integrated over the entire polar region, with similar correlation coefficients. There was a \nsubstantial decrease in ClO amounts during 2002-2004. There has been no systematic change in the timing of \nchlorine deactivation attributable to secular change in the Antarctic vortex", "description": "4 p.", "publisher": { "@type": "Organization", "name": "U.S. Geological Survey" }, "author": [ { "@type": "Person", "name": "Barrett, James", "givenName": "James", "familyName": "Barrett" }, { "@type": "Person", "name": "Parrish, Alan", "givenName": "Alan", "familyName": "Parrish" }, { "@type": "Person", "name": "Connor, Brian", "givenName": "Brian", "familyName": "Connor" }, { "@type": "Person", "name": "Solomon, Philip", "givenName": "Philip", "familyName": "Solomon" }, { "@type": "Person", "name": "Mooney, Thomas", "givenName": "Thomas", "familyName": "Mooney" } ], "spatialCoverage": [ { "@type": "Place", "additionalType": "unknown", "name": "Antarctica" }, { "@type": "Place", "geo": [ { "@type": "GeoShape", "additionalProperty": { "@type": "PropertyValue", "name": "GeoJSON", "value": { "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {}, "geometry": { "type": "Polygon", "coordinates": [ [ [ -180.0, -90.0 ], [ -180.0, -60.0 ], [ 180.0, -60.0 ], [ 180.0, -90.0 ], [ -180.0, -90.0 ] ] ] } } ] } } }, { "@type": "GeoCoordinates", "latitude": -75.0, "longitude": -0.0 } ] } ] } }
