Spatial Distribution map displays with sampling sites around the world and allows selection of fewer sites for subsequent analyses. Map can be scaled down or up by using the zooming tool. The sites are stratified by site type and UNEP region. This map is interlinked with the data selection module and displays only those sampling sites included in the selection.
This is overview of data in a selected data set.
Available Data – Parameters shows frequency of individual chemical parameters. The more data are available on a site for a parameter, the larger and darker the symbol appears. All symbols are clickable. The user then obtains a summary table for relevant point.
Available Data on Site
Available Data – Time shows availability of data over time for a given site. Green rectangles represent samples in years within the selected sampling period. The more data are available, the larger and darker the rectangle appears. All rectangles are clickable. The user then obtains a summary table for relevant point.
Summary Statistics chart presents interval of measured concentrations for a compound in a given matrix in individual years. The horizontal box-whisker chart shows a central point (median, mean, geometric mean) and its variability (minium and maximum, standard deviations, percentiles) for a set of sampling sites in individual years.
Time Series menu offers three views:
Multiple sites Trend Map shows the summary development in the selected area (single compound and selected matrix)
Time series Analysis provides time trend on individual site for selected compound and matrix
Time Series Bar Chart Map shows concentration changes in bar charts for multiple sites in a map
