Dual-polarized weather radar can estimate the number of bats in a swarm similar to the way it can estimate the number of raindrops in a cloud.
NSSL deployed the NOAA X-Pol mobile radar in southwestern Colorado over the weekend as part of the Southwest Colorado Radar project to collect data on snowfall in the area. The project continues through the end of February, 2011.
Recent analysis of data from NOAA NSSL’s prototype dual-polarization radar during a significant tornado outbreak in central Oklahoma this past spring showed debris from a damaging tornado. This critical information can help a forecaster confirm the presence of a rain-wrapped tornado, or a tornado at night causing damage on the ground. Current NOAA National Weather
NSSL researchers successfully launched two balloon borne prototype instruments into a large thunderstorm complex at the end of October.
Flash floods are the number one hazardous weather-related killer in the US, yet they remain poorly observed. An NSSL project now collects data from the public on flash flooding, in addition to hail and wind reports.
