Stream instantaneous nitrate - discharge 1985-2004, Auradé

The data are instantaneous nitrate concentrations and discharge of stream waters collected at the catchment outlet by operators combined with sampling done by automatic samplers more frequently during flood event periods. The data period is 1/10/1985 to 30/09/2004.
These data are complementary to nitrate concentrations data that can be found in the file "Stream instantaneous hydro-physico-chemistry" by 01/10/2004.
In order to ensure the consistency of discharge, the discharge rating curve used is the same as for the period by 01/10/2004 (see the discharge page for details of the rating curve).
