LARS Tech Report Number
The measurements program at LARS/Purdue has been concerned with five basic research areas during 1971. These areas are (1) the influence of haze layers upon remotely sensed surface properties, (2) electrical methods of soil moisture measurement, (3) thermographic studies of vegetation under nutritional stress, (4) improved field spectroradiometry, and (5) biological spectrophotometry.
All of the projects have risen out of problems generated from the overall laboratory mission. the emphasis in the paper is on instrumentation and techniques; whereas, related data and results on specific projects will be reported elsewhere. Each of the subject areas will be discussed individually.
