A product which shows an intense gate-to-gate azimuthal shear, associated with tornadic- scale rotation. So for the example you reference, replace N0Q with N0B and everything should work as before. I'm open to requests or pull requests that add additional parsing algorithms. Are you sure you want to create this branch? Since 2003, the IEM has been generating and archiving nationwide mosaics of NEXRAD base reflectivity every 5 minutes. Streams are not supported.

If appropriate, NCEI can only certify that the data it distributes are an authentic copy of the records that were accepted for inclusion in the NCEI archives. Doppler radars detect atmospheric precipitation and winds, which allow scientists to track and anticipate weather events, such as rain, ice pellets, snow, hail, and tornadoes, as well as some non-weather objects like birds and insects. Dual Pol radar capability adds vertical polarization to the previous horizontal radar waves, in order to more accurately discern the return signal. Level codes 0 and 1 correspond to 'Below Threshold' and 'Range Folded', respectively, while level codes 2 through 255 correspond to the reflectivity data itself".
