Available in PDF, EPUB and Kindle. Book excerpt: Five different instruments were used in multiple experiments to measure atmospheric turbulence in the form of the refractive structure constant, C sub n squared. These included UHF radar, optical scintillometer, modified radiosondes, AFGL thermosondes, and aircraft micro-thermal measurements. Described here are the radiosonde and thermosonde electronics and their calibrations. The data reduction scheme is described and a brief program description is given. Although the different instruments gave measurements somewhat separated in space and time, first results show good agreement between the radar, scintillometer, and thermosonde measurements.

Download or read book Study of Possible Solar Heating Effects on Thermosonde Probes written by James H. Brown and published by . This book was released on 1989 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermosonde data reveals a diurnal daytime shift in measured levels of C square (n) in the free atmosphere. The shift is manifested in two ways. First, an apparent offset in the smallest measured values of C square (n) exists. Secondly, the curve of the average profile shows an enhancement over nighttime profiles. Related optical and radar measurements have indicated that differences between day and night probably exist, but because of limited instrumental resolution and altitude capabilities those results are inconclusive. Several hypotheses have been put forward in this paper concerning possible instrumental or solar based sources of data contamination. We have examined the possibility that solar radiation causes probe heating with subsequent instrumental effects. Calculation, computer simulation, and direct measurements have shown that the sun heats the body of the probe sensor a couple of degrees above the ambient and that the level of heating depends upon the solar aspect angle and magnitude and direction of air flow over the probe. A small but insignificant AC type effect can result from improper probe geometry or probe mismatch together with a coupling of solar heating with velocity turbulence. Transient and DC type effects can occur, but measured, processed, and transmitted root mean square C square (n) information is not likely to contain instrumental contamination.
