The IIWQ Water Quality Portal is a free visualiser of satellite derived water quality information for worldwide lakes and rivers.

A global set of parameters in 90m spatial resolution is provided on a continental base for each of the UNESCO Regions. Access to time series products in 30m spatial resolution is available for pilot regions, one per continent, covering the year 2016.

This application allows you to interactively browse water quality products. You can use the features on the right hand side to select your region of interest, select various water quality parameters, set any desired virtual sampling stations, gather values and time series information.
