Reflectivity and velocity radar
WebThe radar has been collecting measurements discontinuously for the period between 16 December 2024 and 5 February 2024, usually being manually activated before precipitation events. The position of the radar has been chosen as a trade-off between ease of access, needing to operate it on a regular basis, and visibility on the mountain range. http://research.atmos.ucla.edu/weather/C110/Documents/tmp/basic_wxradar/print.php.htm
