The Northern Colorado Radar Loop uses output from the WSR-88Ds located in Cheyenne, WY, Denver, CO, Goodland, KS, and North Platte, NE. The images are generated from Level-II base reflectivity data. The echo intensity is measured and plotted in dBZ. Only the last 30 scans are included in this loop (Note: data is not archived). The frequency that the imagery is updated and the temporal resolution between scans is dependent upon the radar's scanning mode (Volume Coverage Patterns - VCP).
