Reliable, high-quality, accurate and carefully navigated DOW data have been at the core of analyses of winter storms, convective initiation, hydrology, severe wind/damage relationships, orographic precipitation, hurricane boundary layer structure, tornado genesis and structure and other analyses. Solid (stippled) black lines are ρhv (ZDR) signatures. Even though observing geometry and wavelength are different, excellent agreement exists between the DOW and 88D, but much finer-scale detail is evident in the DOW6 data. Inter-comparison of dual-polarization products between the S-Band WSR-88D (top) and the X-Band DOW6 (bottom) radars during the El Reno tornadic supercell at ~2319 UTC. Thus, there was a need for finescale observations of these phenomena in order to better understand the mechanisms involved in their formation and maintenance. Finally, these phenomena frequently occur on timescales of seconds to minutes and thus are sampled poorly by typical surveillance radar scanning strategies. Near-ground (<300 m AGL) structures are often undetectable due to the masking of the transmitted beam by topography and obstructions, vertical beam spreading, and earth curvature. This results in finescale (sub-kilometer) structures being unresolvable due to beam spreading between stationary radars and the targets. Additionally, many interesting physical processes occur at sub-kilometer scales, but the ranges between the phenomena of interest and the stationary radars are almost always quite large. These are difficult to measure with traditional stationary meteorological radars, due to temporal and/or spatial limitations. Many important meteorological phenomena (such as tornadoes, hurricanes, microbursts, dust devils, etc.) occur infrequently and/or very near the ground. In addition, the DOW Facility can deploy up to five GRAW radiosonde stations, as well as multiple pole-mounted ground value mesonet stations. The DOW facility consists of four mobile radars (DOW6, DOW7, the Rapid-Scan DOW (DOW8) or just DOW8 depending on its configuration, and C-band DOW), three support vehicles outfitted as mobile mesonets, a mobile office and maintenance/repair van and an array of quickly-deployable weather stations (Pods) that can be carried at low cost in the support vehicles/mobile mesonets (see image below). Projects utilizing the DOW radar facility They have deployed at 18 universities and participated in extensive nationwide outreach tours impacting over 100,000 students. The DOWs are frequently requested and allocated for education and outreach. DOWs have been requested for several field programs (e.g., PECAN (2015), OLYMPEX (2015), SNOWIE (2017), RELAMPAGO (2018) and PERiLS (2021)). The DOWs have been among the most widely used radar facilities, participating in over 30 field campaigns since VORTEX1. Prior to then, the DOW Facility operated as the Center for Severe Weather Research (CSWR). The DOW radar facility has served the scientific community as part of the University of Illinois since 2020. Since the configurations are minimal, this software is very well suited for beginners and pretty much everyone who needs to save as much time as possible in establishing wireless connections on the go.The Development of Mobile Radar: Doppler on Wheels Overall, Easy WiFi Radar is just a simple app that does what it's supposed to do with no hassle, helping you to connect to free wireless networks. For example, you have the option to enable the radar sound or not, open a given page when a new connection is made or save your home or office WEP key for instant connection. Still, the settings menu is pretty basic, so you can't configure too much about Easy WiFi Radar. Shaped like a radar, the main window comes with few options, to minimize the app or start a new scan, but more features are accessible via the System Tray icon. The interface isn't quite the one you'd expect from such an application, but it still serves its purpose quite well. The program has the power to continuously search for free access points, so as soon as it detects a new network, it automatically establishes a connection, thus letting you retrieve emails or resume downloads on the fly. It doesn't waste your time with setting up network searches or other WLAN configurations. Automatically setting up connectionĭesigned to deliver you from that burden, Easy WiFi Radar is an application that will lend a hand when you're trying to connect to a wireless access point on the go. Enjoying the benefits of the Internet while not at home or at work usually means having a payed subscription to a service provider or simply paying a fee for each session.
