GENASIS Data Browser – OUTDOOR

The GENASIS (Global ENvironmental ASsessment Information System) complex multi-matrix data browser has been developed to view environmental data collected within different monitoring projects, institutions, and matrices. Monitored compounds cover most of these listed in the Annexes to the Stockholm Convention on Persistent Organic Pollutants.

Data of the Research Centre for Toxic Compounds in the Environment (RECETOX) count for the vast majority of the database with Košetice EMEP station and MONET networks being the most significant data sources. In addition, short-term and screening projects are also included in the database. Furthermore, the browser also allows visualization of data provided from partner institutions as follows:

  • Environment Canada, project GAPS (Global Atmospheric Passive Sampling) – a worldwide network of ambient air monitoring by passive sampling
  • Central Institute for Supervising and Testing in Agriculture (CISTA) – institute performing soil monitoring in the Czech Republic

Other Core Matrices

Available Tools

→ Spatial Distribution

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.

→ Available Data

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

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

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
