Abstract
The results of synchronous ship observations and NOAA-AVHRR IR surveys of Lake Ladoga are analysed. The possibility of temperature calibrati on of the satellite data without using ground information is discussed . The water with the greatest density (4-degrees-C) associated with th e Spring frontal thermal zone, is used as a reference; this is identif iable from the extremal values in the brightness histogram.
