Summary

The polar-orbiting Advanced Very High Resolution Radiometer (AVHRR) was evaluated as a means of detecting and measuring surface water temperatures of selected Pools of the Upper Mississippi River System. In summer 1994 Pools 4, 7, and 8 were monitored and, despite heavy cloud cover and fog, useful results were obtained. Satellite mean temperatures were within about 1 Celsius degree of in situ temperature means for nine observation dates for the three pools. A split window procedure, combining the radiance of thermal infrared bands 4 and 5, greatly improved the accuracy of temperature estimates. Routine temperature monitoring could become a reality when some of the logistical problems encountered in this study are addressed. In particular [...]
