An Experimental Study of Transport in a Vineyard on a Hill - PTRAC 2014

The purpose of this project was to examine the transport of momentum, scalars, and heavy particles like fungal spores in a trellised agricultural canopy. To study these interactions, particle dispersion experiments were performed Sept 2-4, 2014 at Lone Star Vineyard (138 acres of wine grapes, 44 deg 4′ 8′′ N, 123 deg 5′ 48′′ W) near Amity, Oregon while high frequency wind and temperature data were collected.

Instruments:
-* Distributed Temperature Sensor fiber optic
- Sensornet Oryx: 1 m sampling resolution
- 900 micron AFL simplex fiber strung horizontally along _101 m_ vine at 6\" vertical spacing at Tower 1
- 12 horizontal lengths looping through the baths (one cold, one ambient) at one end each time for the turn around
- DTS data starts at 11:28 on August 28th and ends at 12 on September 5, 2014. Up until 10:07 on September 1, only the first 898m of the fiber was captured, which corresponds to 7 lengths of fiber across the trellis. After 10:56, the DTS was reconfigured to write out data for the entire fiber length, corresponding to 12 fiber lengths.

- 3 Meteorological Towers
- 6 LEMS Towers
- Radiation Sensors (CNR1, LI200) at T1
- Soil sensors (HFP01, CS616, & TCAV) at T1
- 7 PAR sensors. 3 in canopy, 3 below at T1
- 18 Leaf surface temperature thermocouples
