Movies of Plan Position Indicator (PPI) and RHI scans for Colorado snow storms.
In the PPI movies, images are (first row) radial velocity, spectral width (a proxy for turbulence), (second row) reflectivity, snow rate, and (third row) differential reflectivity. Teal lines denote the azimuths used for RHI scans.
In the RHI movies, images are (top to bottom) radial velocity, spectral width (a proxy for turbulence), reflectivity, snow rate, and differential reflectivity.
