Disdrometer Performance Optimization for Use in Urban Settings Based on the Parameters That Affect the Measurements

Having information about the amount of rain, the composition of the precipitation particles and visibility are essential to avoid accidents, which requires intelligent systems that warn drivers and redirect traffic. However, few studies related to Intelligent Transport Systems (ITS) have been performed regarding why these devices are not optimized for this type of applications. Therefore, this paper analyzes and evaluates the operating mode of these equipment through their theoretical model, which will allow the design of prototypes of disdrometers with different characteristics. In addition, this model will be implemented in a simulation program, through which an exhaustive study analyzing how the type of precipitation and its intensity affect the measures provided by the model will be conducted. -
Workshop on Weather Ready Nation: Science Imperatives for Severe Thunderstorm Research, Held 24-26 April, 2012 in Birmingham AL
Workshop on Weather Ready Nation: Science Imperatives for Severe Thunderstorm Research, Held 24-26 April, 2012 in Birmingham AL Sponsored by National Oceanic and Atmospheric Administration and National Science Foundation Final Report Edited by Michael K. Lindell, Texas A&M University and Harold Brooks, National Severe Storms Laboratory Hazard Reduction & Recovery Center Texas A&M University College station TX 77843-3137 17 September 2012 Executive Summary The National Oceanic and Atmospheric Administration (NOAA) and the National Science Foundation (NSF) workshop sponsored a workshop entitled Weather Ready Nation: Science Imperatives for Severe Thunderstorm Research on 24-26 April, 2012 in Birmingham Alabama. Prior to the workshop, teams of authors completed eight white papers, which were read by workshop participants before arriving at the conference venue. The workshop’s 63 participants—representing the disciplines of civil engineering, communication, economics, emergency management, geography, meteorology, psychology, public health, public policy, sociology, and urban planning—participated in three sets of discussion groups. In the first set of discussion groups, participants were assigned to groups by discipline and asked to identify any research issues related to tornado hazard response that had been overlooked by the 2011 Norman Workshop report (UCAR, 2012) or the white papers (see Appendix A). In the second set of discussion groups, participants were distributed among interdisciplinary groups and asked to revisit the questions addressed in the disciplinary groups, identify any interdependencies across disciplines, and recommend criteria for evaluating prospective projects. In the third set of discussion groups, participants returned to their initial disciplinary groups and were asked to identify and describe at least three specific research projects within the research areas defined by their white paper(s) and to assess these research projects in terms of the evaluation criteria identified in the interdisciplinary groups. -

Comparison of the Compact Dopplar Radar Rain Gauge and Optical
Short Paper J. Agric. Meteorol. 67 (3): 199–204, 2011 Comparison of the compact dopplar radar rain gauge and optical disdrometer Ko NAKAYA†, and Yasushi TOYODA (Central Research Institute of Electric Power Industry, 1646 Abiko, Abiko, Chiba, 270–1194, Japan) Abstract The operations of a compact Doppler radar rain gauge (R2S; Rufft, FRG) and optical disdrometer (LPM; THIES, FRG) are based on raindrop size distribution (DSD) measurements. We checked the instrumental error of these sensors and compared each sensor with a reference tipping-bucket rain gauge. This is because both rain gauges can detect fine particles and so they can function as rain sensors. The R2S has a measuring bias of rainfall intensity when the drop size distribution differs from the assumed statistical DSD model. The instrumental error on the LPM is small; in fact, the LPM shows good agreement with the reference rain gauge. Where the atmospheric density differs remarkably from the standard elevation, as is the case in highland areas, the R2S requires calibration using a reference rain gauge. The resultant calibration coefficient of the R2S to convert the reading into a reference tip- ping-bucket rain-gauge equivalent was 0.51 in a forest at an elevation of 1380 m. Further gathering of calibration coefficients obtained at different elevations will improve the R2S’s applicability. Key words: Doppler radar rain gauge, Drop size distribution, Optical disdrometer, Tipping-bucket rain gauge. Although the accuracy and suggested errors of rainfall 1. Introduction observations using typical Doppler radar have been Rainfall properties, such as the intensity, amount, reviewed in many studies (Maki et al., 1998, for duration, and type, constitute important meteorological example), reviews for the R2S compared to a reference information that is useful for agriculture and forestation rain gauge are few. -

Interview with Sean Casey
INTERVIEW WITH SEAN CASEY YOU HAD COME UP WITH THE IDEA FOR THE TIV WHEN YOU WERE LOCKED OUT OF A MINIVAN IN A STORM, CORRECT? Well, actually, we had come up with the concept the year before, but getting locked out of a minivan with a tornado right next to us, that kind of confirms my sneaking suspicion that if we were going to be that close we should have something a bit more rugged. WERE THERE ANY OTHER INSPIRATIONS FOR THE TIV? Mainly it was just a feeling that, you know, there’s a huge difference between filming a tornado from a couple miles away with a telephoto lens, and filming a tornado that’s on top of you with a wide-angle lens. And that’s really where all the action is. It’s right next to the tornado. And it’s close in the tornado. That’s the kind of power that I wanted to capture. I wanted to get footage that really was as powerful as the subject matter. HOW DID YOU FEEL DURING THE GOSHEN INTERCEPT? Of course it’s hard to describe. In the moment, a part of you is fearing for your life. A part of you is just overjoyed and kind of in shock. I think I was in shock at the time, really. It was such an unbelievable experience. Unbelievable to see a tornado forming half a mile away. You pick the right spot, and it’s just coming right at you, and to bear witness to that. And another thing is I’m trying not to mess up. -
