REMOTE SENSING BY INFRARED AND MICROWAVE RADIOMETRY. I. BASIC PRINCIPLES. II. A TECHNIQUE FOR THE CORRECTION OF AIRBORNE MEASUREMENTS OF APPARENT SURFACE TEMPERATURE OF NATURAL WATER BODIES. III. POTENTIAL APPLICATIONS OF INFRARED AND MICROWAVE RADIOMETRY.
Abstract
The basic principles involved in the remote sensing by passive techniques in the infrared to microwave region of the electromagnetic spectrum are discussed. Whereas the radiation below ten micron wavelength has found distinct application in many fields, the region between 0.1 to 10 cms has a decided advantage in situations where the atmospheric constituents interfere. Consideration is then given to the specific problem of atmospheric interference in the 8 to 14 micron wavelength region due to water vapor and carbon diozide. A technique for correcting radiometric measurements of surface temperatures for interference by these two constituents is suggested. The final portion deals with the potential applications of infrared and microwave radiometry to the measurement of surface temperature of natural water bodies, horizontal temperature gradients, and the heat flux across the sea-air interface. The relative advantages of infrared and microwave techniques are compared. (Author)
