T-28 Participation in the North Dakota Thunderstorm Project(NDTP)
The T-28 research aircraft participated in the North Dakota Thunderstorm Project, centered
at Bismarck, ND, from June 12 - July 22, 1989. The focus of investigation included the
study of transport, dispersion, and entrainment, and ice initiation and evolution.
The primary role of the T-28 was to penetrate upper regions of convective clouds following
the dispersal of sulfur hexafluoride (SF6), radar chaff, and/or fluorescent beads in lower
regions of the cloud. Instrumentation on-board recorded SF6 levels, as well as collecting data
on the hydrometeor spectrum from micrometer-sized cloud droplets to centimeter-sized
hailstones. The standard package of instruments provided for the
determination of temperature, vertical wind, electric fields, water content, etc. During NDTP the
T-28 carried a PMS 2D-C optical probe.
