A WET-AND DRY-BULB TEMPERATURE MEASURING SYSTEM FOR MICROMETEOROLOGICAL APPLICATION.
Abstract
This report reviews the construction of a wet- and dry-bulb temperature measuring system based on a prototype developed for use on Project Green Glow under Contract Number AF 19(604)-4562. Condensed descriptive and schematic representation of the developed system in the engineering as well as the meteorological sense is included. Field testing procedures are thoroughly described, but because of bulk the test data have been summarized. The system will provide wet-bulb depression to within .25C, in digital form, at five-second intervals for depression magnitudes in excess of 15C. Fow lower depression rates the resolution is less than .1C at the five-second sampling rate. Resolution for averaged intervals of the order of five minutes or greater is within .05C for depression magnitudes below 15C, excepting saturation conditions for which no evaluation can be given inasmuch as such conditions were not met at the field testing site during the contract interval. All of the preceding resolution evaluations are applicable under any and all natural conditions of radiation and wind. (Author)
