MULTIBAND RADIOMETER FOR FIELD RESEARCH.

The radiometric instrument will be a multiband radiometer with 8 bands between 0. 4 and 12. 5 micrometers; the data acquisition system will record data from the multiband radiometer, a precision radiation thermometer, and ancillary sources. The radiometer and data handling systems will be adaptable to helicopter, truck, or tripod platforms. The system will also be suitable for portable hand-held operation. the general characteristics of the system are that it will be: (i) comparatively inexpensive to acquire, maintain, and operate; (ii) simple to operate and calibrate; (iii) complete with data handling hardware and software and (iv) well-documented for use by researchers. The instrument system is a prototype of an economical system which can be utilized by many researchers to obtain large numbers of accurate, calibrated spectral measurements.
