Spatial sampling in the presence of a trend

Journal of Statistical Planning and Inference, 1981
Abstract The spatial sampling designs suggested by Quenouille (1949) are investigated under a number of trend assumptions, namely a linear trend, linear trend and periodic variation, and spatially correlated populations. The results obtained provide a planar analogue to the one-dimensional results appearing in Cochram (1977, Ch. e). Centrally located

Spatial Mapping of Ozone and SO2 Trends in Europe

Science of The Total Environment, 2010
This article investigates the spatial mapping of temporal trends in air quality for all of Europe. Such spatially distributed maps provide information for policy making and for understanding the spatial character of air quality trends. Previous trend studies have concentrated on individual, or groups of, monitoring sites looking at the trends of these.

Spatial trends in the sighting dates of British butterflies

International Journal of Biometeorology, 2003
A strong relationship between appearance dates and temperature has been demonstrated over two decades for most British butterflies. Given this relationship over time, this paper tests whether comparable spatial trends in timing are also apparent. A major survey of British butterflies is used to calculate mean sighting dates of adults across the country,
