The purpose of the T-28's participation was to provide a dataset from penetrations of cloud regions normally inaccessible to conventional research aircraft. The emphasis was on microphysical observations, but supporting thermodynamic, kinematic, and electrical data were also obtained. The data will assist in the determination of possible seeding effects, as well as providing information about precipitation mechanisms.
The standard package of instruments provided for the determination of temperature, vertical wind, electric fields, water content, etc. During PACE the T-28 carried a PMS 2D-C optical probe.
