The Community Collaborative Rain, Hail, and Snow Network (CoCoRaHS) will present a WeatherTalk webinar (an online web-based seminar) entitled “Educated Echoes: An Introduction to Doppler and Dual-polarization Weather Radar” on Thursday, February 7th at 12 noon Central Time. The following is a description of the topics that will be covered:

“Weather radar images showing the geographic distribution and intensity of precipitation are routinely distributed via both broadcast television and the internet. These images have historically been based on the strength of the received radar signal (the “echo”). Recent technological advances have expanded the range of measurements that can be made by National Weather Service (NWS) radars. These enhanced measurements include radial (Doppler) velocity as well as several additional quantities that have become available through the ongoing NWS upgrade to dual-polarization operations. This talk will provide a basic introduction to the measurements made by dual-polarization Doppler weather radars. Example observations collected by the National Science Foundation-sponsored CSU-CHILL radar will be presented.”

The webinar is free, but registration is required and space is limited to 500 participants. To register, please visit this website: https://www3.gotomeeting.com/register/278818910. If you are unable to attend the webinar, a replay will be made available for viewing a short time after the presentation.
