Figure 1. Map of northern California showing the location of the Integrated
Ocean Observing System wind profiler technology evaluation site at the
University of California's Bodega Bay Marine Laboratory (BBY).
Figure 2. The integrated 915-MHz wind profiler and Radio Acoustic Sounding
System (RASS) at Bodega Bay, California. The 2-m square phased-array radar
antenna is located at the bottom of the pyramid-shaped white clutter fence
shown near the center of the picture. The blue corrugation panels are used
to help reduce side lobe diffraction from the top edges of the clutter
fence. The antennas and sound sources for the four RASS units sit at the
bottom of the beige boxes.
Figure 3. The ΒΌ-scale 449-MHz wind profiler at Bodega Bay, CA. The radar
antenna consists of a 7.3 m square lattice of coaxial-collinear antenna
elements attached to the top of a metal ground plane. The antenna elements
are fed by cables from underneath the ground plane. The radar electronics,
including transmitters, receivers, and control computers for both wind
profilers are located in the white trailer.
Figure 4. Radio Acoustic Sounding System (RASS) profile measurements of
virtual potential temperature (Θv) recorded with the 915-MHz
wind profiler at Bodega Bay, California (colored rectangles). The shallow
marine inversion is clearly indicated by the vertical gradient in
Θv. Wind profiles measured by the wind profiler are
indicated by the black wind barb symbols. Time recorded on the x-axis
proceeds from right to left.
