Nile, River Africa, Sudan Volume Surface Area Water Level

Water Leve Time Series

The water level time series are based on normal heights w.r.t. geoid model.
The error plot shows the formal errors of the water level time series resulting from the Kalman filtering.

Data by Satellite

Data Used

Altimeter Data

The data of the following altimeter missions and corresponding passes have been used for the estimation of the water level time series. An additional '*' indicates that an additional retracking of the altimeter measurements was performed.
