Miniaturized instruments on the aircraft, which typically flew in
formations of three, measured a range of properties such as the
quantity and size of the aerosols on which cloud droplets form. The
instruments also recorded variables such as temperature, humidity and
the intensity of light that permeates clouds and masses of smog. These
comprehensive measurements were made at a very low cost when compared
to traditional manned flights.
