Notes

Model assumes the same turbidity sensor is being used over all time, but that is not the case. Starting in 2005, this station switched from a YSI 6026 to a 6136, whose measurements typically are only about 2/3 of the 6026's. Thus, for 2005, this model will underestimate dissolved nitrate plus nitrite.
