Subject:
SGP/CO2FLX/C1 - Met stand was moved
DataStreams:sgp30co2flx4mmetC1.b1
Description:
Ameriflux program (Hank Loescher from Oregon state university) visits the site to 
intercompare his instruments with our 4m flux system.
The met stand was moved by 30 feet and consequently:
1. Soil moisture sensors were disconnected,
2. Soil temperature sensors were disconnected,
3. Soil heat plates were disconnected,
4. The true direction of the anemometer boom was 230 degrees instead of the regular 270 
degrees.
Suggestions: 
Wind direction should be corrected by users.
