What are we Measuring with Eddy-Flux?
• 3-Dimensional wind speed and direction
• Incoming/outgoing radiation
• CO2, O2, and H2O vapor concentration
• Temperature• Relative Humidity• Precipitation
Taken every 0.25 seconds!
Atmospheric-vegetation interaction
Climate change modeling
Net Primary Productivity, Etc.
Current Tower in KREW P301
Concrete base and guy wire footing
160’ total Height
Anti-climb signage and hardware
Power infrastructure on temporary scaffold at KREW P301
~1 kW Solar array
15 foot tall
Footings in soil/rock
Current Site LocationP301 tower in Kings River Experimental Watershed
Proposed Tower LocationsSoaproot Saddle Tower:37° 1'51.85"N119°15'23.15"W
Courtwright Tower:37° 3'59.75"N118°59'18.51"W
Instrumentation will provide an elevation transect from the rain dominated to snow dominated hydrologic regimes in Southern Sierra Nevada
The Heavy-Duty aluminum crank-up towers are designed to accommodate antennas with large wind surface areas up to 18sq.ft. and 125 lbs. of dead weight. These models will accommodate a large variety of commercially available rotors and a universal rotor plate is welded in place. This will allow a beam or other directional type antenna to be oriented. Telescoping towers are complete with a heavy duty 2” dia. X .125 wall x 8 ft. long mast, guy ears on each section, heavy-duty building bracket and tilt base.Model T-100HApprox Extended Height: 120 feetWeight: 400 lbs
Temporary base and Telescoping Tower Specifications
Power infrastructure similar to current P301 Tower.
Tower will be T-120H or smaller
Example of telescoping tower in Southern California at Pinyon-Juniper site
