Determining the Velocity of the Upper Layer of Lake Ladoga by Means of Maximum Cross Correlation (MCC)

The first use of Maximum Cross Correlation to calculate the surface currents of Lake Ladoga yields very promising results in the absence of direct measurements of currents. The technique is adapted for a large lake, and new procedures are proposed for selecting the most informative infrared satellite surveys for lake flow analysis. The best conditions, parameters, and limitations of using Maximum Cross Correlation for Lake Ladoga are obtained. Surface current systems are constructed for specific wind situations in the open water period. The technique, based on an analysis of successive satellite IR surveys of Lake Ladoga’s surface, allows the dynamics of the waters to be determined and can be applied to other large lakes.
