Cumulus Photogrammetric, In-Situ and Doppler Observations (CuPIDO) is an observational program designed to examine the onset and development of orographic thunderstorms associated with the North American Monsoon. The CuPIDO field program used digital visible spectrum cameras, surface mesonet stations, high temporal resolution soundings and aircraft data.
