EDENZ – accessing historical data
![](/sites/default/files/styles/large/public/sites/default/files/images/imported/0003/58557/edenz-200_2.jpg?itok=agQkB53L)
An example of EDENZ long-run data – river flow.
“How has the level of that river fluctuated since irrigation-take began six years ago?”
EDENZ provides archived data of river flows, river levels, rainfall, plus climate and some air quality data, for downloading, while near-real-time data can be viewed. Data from NIWA’s sea level monitoring network is also available.
Since EDENZ data became freely available recently, use has increased by about 800%. Two thirds of all visitors stay long enough to view at least one graph, and most data downloads have been of river flow and sea level data. http://edenz.niwa.co.nz
