The NCAS X-band mobile radar is now collecting data operationally in Cumbria. The images above show data collected by X-band radar at 1:33AM on 1st November 2018. In Figure (a) we are showing radar reflectivity which is one of the basic variables that a radar observes. Radar reflectivity is proportional to the amount of rainfall so higher values equate to areas that are experiencing more rain. In Figure (b) we show the rain rate observed from the reflectivity in Figure a. You can see that the areas of highest reflectivity in western Cumbria (near the radar marked with a black dot) were experiencing rain rates of over 10mm per hour. The circles are drawn with radii increasing in 25km steps. The furthest circle is 150km from the radar.
