![]() ![]() All of these caveats must be taken into consideration when viewing nearly all radar data. Wind farms) to avoid a loss of data in critical areas resulting in 'hotspots'. Conversely, some non-meteorlogical returns may be omitted from this post-processing clean-up (Ex. This post-processing is unique to each radar site and may result in some 'blindspots'. What we display is Level 3 radar data which means it has been post-processed to reduce or remove some but not all of these sorts of returns. As such, raw weather radar data is characteristically noisy given how common these types of interference are. Among others, the radar can also see returns from non-meteorological objects such as birds, bugs, dust, terrain, buildings, and other sources of radio waves at similar frequencies. When the attack traffic comes from multiple devices, the attack becomes a DDoS or distributed denial-of-service attack. However these are not the only objects that will reflect the radar signal. A ping flood is a denial-of-service attack in which the attacker attempts to overwhelm a targeted device with ICMP echo-request packets, causing the target to become inaccessible to normal traffic. Meteorological targets would include objects like rain, snow, and hail. Our news apps for iOS and Android devices provide you with the latest breaking news, weather, and sports in the Eugene, Oregon area. Reflectivity, put simply is the amount of return that the radar sees at a given azimuth and range. Radar operates by sending out a radio wave pulse that will interact with objects and 'reflect' some portion of that signal back to the radar reciever. Base reflectivity is the most basic of all NEXRAD products and can be used to illustrate some fundamental principles. ![]()
