The M-33 was located on a knoll about 1 /2 mi. east of the CSU Engineering Research Center, Foothills Campus. A method of launching no-lift balloons to a preselected height was developed. Serial launchings of no-lift balloons were attempted on 2 different days. They were successful on one day. No-lift and rawin balloons were tracked on other days. Thunderstor.ms were observed by the M-33 to determine the modifications required to observed thunderstorms. The capability of the equipment was determined and a system was developed to use in observing thunderstorms.technical reportsengCopyright and other restrictions may apply.
