Application of the ESRI Geostatistical Analyst for determining the adequacy and sample size requirements of ozone distribution models in the Carpathian and Sierra Nevada Mountains

摘要: Models of O3 distribution in two mountain ranges, the Carpathians Central Europe and Sierra Nevada California were constructed using ArcGIS Geostatistical Analyst extension (ESRI, Redlands, CA) kriging cokriging methods. The adequacy spatially interpolated ozone (O3) concentrations sample size requirements for passive samplers was also examined. In case Carpathian Mountains, only a general surface could be obtained, partially due to weak correlation between concentration elevation, small numbers unevenly distributed sites. monitoring network much denser more evenly distributed, additional climatologic information available. As result estimated surfaces precise reliable than those created Carpathians. final maps derived from algorithm based on secondary variables--elevation maximum temperature as well determined geographic trend. Evenly sufficient points are key factor model accuracy reliability.
