Available in PDF, EPUB and Kindle. Book excerpt: Fifty-three AN/TPQ-11 Cloud Detection Radars were procured for Air Force use with most of these being installed at selected Air Force bases for operational use by the Air Weather Service detachments. As these sets are capable of furnishing a great deal of meteorological data that are not otherwise available, Air Weather Service requested AFCRL to conduct a study to determine the effect of geographical and seasonal variations on AN/TPQ-11 observations. Cloud height records obtained with the AN/TPQ-11 Cloud Detection Radar at eight widely separated Air Force Bases are analyzed for possible variations in interpretation that might be required as a function of geographical location an environment. The modes of operation of the sets necessary to obtain useful records with a maximum of information content are specified, and examples of records of the various types of meteorological situations are shown. Analyses of these records for their meteorological content are made, and a number of maintenance procedures are suggested that will assist in obtaining high quality records for analysis. (Author).

Download or read book Preliminary Evaluations of the Use of a 35 GHz Radar for Measuring Cloud Base and Cloud Top Heights written by Kumud R. Biswas and published by . This book was released on 1988 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: To determine the accuracy with which a vertically-pointing 35 GHz radar can detect cloud base and cloud top heights, radar data of this type, collected in earlier research projects, have been compared to cloud heights derived from aircraft, a 5.5 GHz scanning radar, and radiosondes. Comparisons with in situ aircraft observations provide the most reliable means for evaluating the accuracy of the 35 GHz radar. In the absence of precipitation, or in very light precipitation, the heights of cloud bases and cloud tops detected by the 35 GHz radar were within approx 100 m of the heights measured by aircraft flying over the radar. However, very thin clouds were not detected by the radar unless they contained some ice particles. In light to heavy precipitation, the 35 GHz radar underestimated cloud top heights and often could not detect cloud bases. (rh).

Book excerpt: A short review is given of the literature pertinent to the bolometric correction. A recommended scale of bolometric corrections is presented based upon recent model atmospheres for stars of early spectral type, and upon stellar energy distributions synthesized from photoelectric observations of stars later than FO V. The reduction of various photoelectrically determined magnitude and color systems to a common system and the further reduction of these measurements to absolute energy units is discussed in some detail.

Download or read book Cloud Detection Capability of Operational AN TPQ 11 Radar Sets During 1966 1967 written by Arthur J. Kantor and published by . This book was released on 1968 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Standard visual observations of cloud height have been compared with cloud data taken from the AN/TPQ-11 cloud detector, a vertically-pointing, fixed-beam radar set with a wavelength of 0.86 cm. Approximately six months of observations (1966 and 1967) were used at each of four USAF field stations (Yokota AB, Eglin AFB, Myrtle Beach AFB, and Scott AFB) between latitudes 30 degrees and 40 degrees N. Ability of these operational radars to detect clouds averaged 62 percent, which is considerably lower than the 85 percent value determined during development of the AN/TPQ-11 equipment. Consequently, current AN/TPQ-11 records appear to be severely limited as a means of reducing the bias now present in middle and high-cloud climatologies. It has been recommended that procedures be initiated to insure that operational AN/TPQ-11 cloud radars perform up to the capability indicated in earlier tests. Addendum A at the end of this report describes efforts to establish such procedures. (Author).
