. BOMEX bulletin / prepared by BOMEX Project Office. Oceanography Research Caribbean Area 80 geometry were determined from real-time observations and subsequent analysis of photographs; sensor heights were corrected accordingly. The anemometers used were low-inertia, "staggered-six" types of Argonne National Laboratory design, featuring cosine response and a distance constant of 35 cm (Frenzen, 1967a). For measurements based on a semi-stable platform at sea, these instruments were adjusted for flat rather than cosine response by mounting the two three-cup rotors slightly closer together. In this con- figuration, the outputs remain within percent of the true wind speed when the sensors are tilted up to 10° in the direction of the wind; note that a cross-wind tilt does not affect the calibration of the anemometers. Wind signals (70 Hz per m s"!) were mixed and transmitted to the ship through a single, 1,000-ft coaxial cable supported by floats. On board, the signals were demodulated and simultaneously recorded by a multichannel electronic counter for mean values, by a special-purpose digital structure function computer for real-time flux estimates, and by a tape recorder for subsequent computation of turbulence spectra. All sensors were recalibrated in the Argonne wind tunnel immediately after the equipment had been returned to the Figure 1.—The Tern buoy as deployed July 28, 1969^ during BOMEX Period Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
