METHOD OF SEARCHING FOR AND RECOVERING EVENT INFORMATION ON KNOWN TIME PERIOD AND AVAILABLE IN DATABASES Russian patent published in 2015 - IPC G06F17/30 

FIELD: physics.

SUBSTANCE: method includes, using time curves, detecting a period of maximum variation of each parameter; for one of the parameters with the highest gradient from the start date of the aircraft to said period of time, counting a whole number of day periods of variation of the parameter associated with solar activity on the surface of the Earth (illumination); determining probable dates of detecting a hydrodynamic phenomenon; with an interval of several hours during each of said dates, restoring the horizontal two-dimensional structure of the field of the parameter over a limited water area; establishing spatial correspondence of field anomalies and the region of detecting a hydrodynamic phenomenon; obtaining the date of detecting the hydrodynamic phenomenon.

EFFECT: higher accuracy of determining the date of a hydrodynamic phenomenon detected on an image.
