Integrated Ocean Observing System (IOOS) at ETL


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.
