摘要

The optical turbulence conditions at a mountain ridge (North Oscuro Peak, White Sands Missile Range, NM) were determined from observations of fine wire sensors and a sodar (sonic detection and ranging). both instruments provided the temperature structure parameter (C_T~2) from which the refractive index structure parameter (C_n~2) was calculated using local measurements of temperature and pressure. The fine wire measurements were used to calibratethe sodar. Atmospheric measurements shown include wind speed and direction, temperature, and solar radiation snesed horizontally as well as parallel to the west-facing slope. Of particular emphasis isthe relationship of the sodar observations to solar radiation and wind speed and direction. The results are explained in terms of the geometry of the site and the mountain-valley wind regime. Results are shown as average range profiles of C_n~2 sensed at various zenith angles at different times of the day and as contours of C_n~2 in a vetical plane oriented normal to the west-facing slope.
