Beginning with the February 1969 mission,
this gap was partiaily clo.
jo
by sampling at 16-3 km instead of 18.3 km at all Latitudes scleward :
about 35° in beth hemispheres.
The coverage in Figure 3b extends almost continucusly at the
continuity between 10°s
to 16°9S.
Each mission is accomplished by con
ducting return flights northward and southward from each of the four
Air Force Bases Of operation:
Eielson AFB
64°40'N
Mendoza AFB

The volume of aix sampled by each filter is calculated by the
methods developed under Project Stardust and updated by Krazyewski
and are reported as standard cubic meters
