PROCUREMENT In progress.
Tower Nos. 2b and 3 (90-ft. High) and Tower
No. 4 (85-ft. high) have been procured and will be fabricated from portions of
a 200-ft. self-supporting tower and a 200-ft. guyed tower which were originally
purchased for the Meteorological Tower (F&S No. 01119).
CONSTRUCTION
The Low Level Wind System will provide the MIGHTY SKY
program with continuous low level wind data at strategic locations on Johnston
Island. The system will consist of five towers on which wind speed and direction
sensors will be mounted. Tower No. 1 (the existing EG&G 300-ft. tower) will
be structurally modified and will be instrumented with TC furnished wind sensors
at the 80-ft., 145-ft. and 280-ft. levels. Tower No. 3 (90-ft. tower) will be
fabricated and erected at coordinates N 196, 840 and E 197, 135. TC furnished
instruments will be mounted on Tower No.
3 at the 12-ft., 22.5-ft., 43-ft. and
80-ft. levels. A Sandia furnished 3-ft. diameter radome covered parabolic
dish will be mounted at the 90-ft. level of Tower No. 3.
