Subject:	SGP/ECOR/E14 - Flux Measurements Incorrect
DataStreams:	sgp30ecorE14.b1
Description:	The ECOR datastream was corrupted; this happens when the ECOR program produces a datastream of the wrong length (i.e., leaves one or more measurements out). Fluxes and some other measurements are incorrect. Reprocessing will not correct this problem; the raw data are corrupted.

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.
Measurements:	sgp30co2flx4mmetC1.b1: Average of four upper soil moisture sensors(mean_m_soil_upper) Average of four lower soil moisture sensors(mean_m_soil_lower) Average of two upper soil temperature sensors(mean_t_soil_upper) Unit Vector Wind Direction(wdir) Average of two middle soil temperature sensors(mean_t_soil_middle) Average of two lower soil temperature sensors(mean_t_soil_lower) Average of four soil heat flux probes(mean_g_soil)

Subject:	SGP/ECOR/E24 - Half Hours of Data Missing
DataStreams:	sgp30ecorE24.b1
Description:	Individual half hours of data were missing infrequently because of a UPS problem. The extent of missing data is minimal, with only a few to several half hours missing most months. Data quality of the surrounding data times was not affected.

Subject:	SGP/CO2FLX/C1 - Reprocessed: Recalibration
DataStreams:	sgp30co2flx4mC1.b1
Description:	The 4m CO2 flux system was calibrated on May 25, 2005. After the calibration was performed, calibration coefficients used to measure CO2 density were not updated. This added an OFFSET to the CO2 density measurements. The data have been reprocessed to address the offset. The reprocessed data were archived in December 2008. Please retrieve the updated files for use in your analysis.
Measurements:	sgp30co2flx4mC1.b1: Mean CO2 density(mean_c)
