Hydrological Observatory of Athens

Hydrological Observatory of Athens (HOA) is a service operated by the National Technical University of Athens and provides hydrological information from the greater area of Athens.

It is an evolution from the hydrometeorological network METEONET and provides access to a single database, which will gradually incorporate further stations and hydrological measurements, including the ones of the Experimental Basin of Athens – XBasin.


Here you will be able to locate hydrometeorological stations on the map, download historic time series and use advanced applications for a statistical analysis of selected hydrological data.
