The Washington Special Action Group, Working Group C, has
directed the .development of photographic requirements for Indochina
subsequent to the cease fire agreement.
Part of this is a priority requirement for high resolution
photography of the North Vietnamese coastal areas. Since overflight
of North Vietnam is prohibited, an IDEALIST U-2R with the "H'! camera
represents a flexible, responsive capability to obtain this coverage.
This mission, to evaluate the capability of the "H" camera
system to obtain this photography, has been requested by the WSAG,
Working Group C.

IV. CLIMATOLOGY
A. GENERAL:
The transition period to a southwest monsoon begins in April
and becomes southwest by the end of May. Low level winds in early.
April tend to be unorganized but prevail from the southwest by months
end. A more westerly surface trajectory or a weakening of the east
wind component tend to decrease coastal cloudiness in late March
and April.
B. CLOUDINESS:
Mean cloudiness is near 80 percent in April. As a general
rule, cloudiness is greatest near the coast during this month being
heaviest north of 19? N. Aircraft flying at high altitudes would be
expected to encounter clear to scattered conditions at. individual
targets on 2 to 5 days north of 19? N, and on 6 to 10 days south of 19? N.
