The T-28 participated in the Texas EXperiment in Augmenting Rainfall through Cloud Seeding (TEXARC) during August, 1994 at Big Spring, Texas. The goals of the project included documenting the physical processes operating within vigorous supercooled convective towers and to conduct a randomized seeding study of convective clouds and complexes.
The T-28 was used to penetrate the core of these clouds, both seeded and unseeded, to provide measurements which would enable investigators to corroborate or modify models based upon earlier experiments. The T-28 also had the assignment of helping to assess whether or not a cell was a suitable candidate for the experiments.
The standard package of instruments provided for the determination of temperature, vertical wind, electric fields, water content, etc. The T-28 carried a PMS 2D-P optical probe.
