It is shown that the principal indicator of the phenomenon is an anomaly in the seasonal variation of total ozone content (TOC). During the spring, when a TOC maximum should be observed in the \"normal\" seasonal variation, its considerable decrease occurs annually over a prolonged time (more than a month). The anomaly in the year 2000 especially graphically revealed a definite role of meteorological conditions in the appearance and development of the anomaly. It is demonstrated that in the majority of latitudinal zones a TOC minimum was observed that had begun about 1990 in the equatorial region and gradually propagated poleward. Over the greater part of the globe, the TOC minimum was observed earlier than the maximum stratospheric concentration of chlorofluorocarbons.","PeriodicalId":405012,"journal":{"name":"Mapping Sciences and Remote Sensing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132710401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This transformation relies on a polynomial function and specific factors such as a building's height and density of tie points. A modified form of polynomial is first considered and is subsequently applied for selected control points from a digital surface model and an aerial photograph. Then, the polynomial model of these control points is established. During the process of transformation, all pixels of an aerial photograph are transferred to a digital surface model with a positional accuracy of 2 and 8 pixels at control points and tie points, respectively. However, when height and density of tie points are included in the transformation, the accuracy increases to 1 and 2 pixels at control points and tie points, respectively.","PeriodicalId":405012,"journal":{"name":"Mapping Sciences and Remote Sensing","volume":"363 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115985551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
