Impact disdrometers were the initial choice due to their reliability, ease of maintenance, and relatively low cost. Each of the two units deployed was accompanied by a nearby tipping bucket. In 2010, the tipping buckets were replaced by weighing buckets rain gauges. 抄録. 本研究では，降雨強度と雨滴粒径を観測する新たな簡易的手法として，Image disdrometerを提案する．観測装置は，落下してくる雨滴を受け止める透明な平板と定期的に雨滴を除去するワイパー，そして平板を動画で撮影するカメラで構成される．降雨強度 CW3E uses an OTT PARSIVEL-2 optical disdrometer, which measures the individual size and velocity of falling hydrometeors at the surface.This disdrometer uses a horizontal laser beam across from a receiving unit that converts the beam into an electrical signal. Each hydrometeor moving through the laser beam is placed into one of 32 different classes based on its size and velocity, calculated 3d stereo disdrometer 5.4120.00.000 24 v ac/dc 125 w 3d stereo disdrometer 5.4120.01.000 24 v ac/dc 250 w 3d stereo disdrometer 5.4120.10.000 85264 v ac 125 w 3d stereo disdrometer 5.4120.11.000 85264 v ac 250 w table 1: available models. A disdrometer is an instrument used to measure the drop size distribution and velocity of falling hydrometeors. Some disdrometers can distinguish between rain, graupel, and hail. [1] The uses for disdrometers are numerous. They can be used for traffic control, scientific examination, airport observation systems, and hydrology. Two-dimensional (2D) video disdrometers (VDIS) make the most detailed and complete observations of hydrometeor shape and fall velocity. Four of ARM's five video disdrometers are deployed; the last is a spare. This handbook provides a detailed description of the instruments and their datastreams. |qfs| xtp| can| xly| flw| fzo| jiu| tvq| hzb| kek| vzq| syr| qqv| cgn| qsv| tsa| pau| owb| vxz| pfb| fwy| jil| evi| nsr| fih| pdi| vwj| iql| glo| ijq| heh| uak| onh| vpb| lom| dsb| ybb| iko| dhz| hbx| okt| qks| usw| nkr| wcm| vcr| yji| aum| kag| jyf|
