For environmental measurements, the anemometers should generate an electrical signal suitable for transmission and recording. Research needs and wind tunnel studies often require sensitive anemometers with frequency responses as high as 10. Hz.

Internal Objectives: Empirical Evidence,gnals which, in turn, are recorded and interpreted. The conversion has been accomplished by a variety of transducers. The information that is presented to the transducer and passed on by it (in converted form) can be classified as to whether the information is in electrical or nonelectrical form.

Soil Heat Flux,rly sums are normally near zero, but daily values can be significant when the soil is heating in the spring or cooling in the fall. Hourly values of the soil heat flux can be large under dry bare soil conditions. Omission of soil heat flux measurements from hourly energy budget analyses will introdu
