Data

The diagrams use the free global CHELSA data set (Climatologies at high resolution for the earth’s land surface areas). For this purpose the data was resampled to a coarser resolution, at the moment the grid size is about 10 square kilometers. This data covers 1981-2010.

Details

The diagram uses D3.js in an ObservableHQ notebook (Compare Climate Diagrams). The map is a Leaflet map, Geolocation is done by LocationIQ.

You can call the page with coordinates to get a diagram of two locations, e.g. https://climate.mapresso.com/compare.html?lat=31.95&lon=35.93&lat2=47.379&lon2=8.554

Feedback

If you have any idea for improvment or the future development, don't hesitate to contact me (links below)!
Some known issues:

  • The size of the diagrams (the integrated observable notebook cells). They should have a constant height.
  • Behaviour of the map (and the search field) on mobile devices
  • ...
