Data Streams:

VR_met Met data collected at Vaira
VR_mp Soil moisture data from the Vaira Moisture Point probes.
VR_flux Half hour averages of the 10Hz flux data.
VR_soilco2 Soil CO2 data collected from nine Vaisala CO2 probes in three profiles.
VR_soilmet Originally the soil sensors (TC, sm, SHF) were on a CR10x. 4-way radiometer and diffuse PAR were added later. All sensors were moved to CR23x on 2004-07-25
VR_pond Monitoring of the pond level.
VR_arable Hourly met data from an Arable Mark device. Raw is roughly 5min periods in UTC which is post processed to 30min data PST at end of averaging period. - stored in PST at end of averaging period.
VR_amp Processed data loaded from the Ameriflux submission files including gap filled and partitioned values
VR_fdwest Forced diffusion chamber near the west soil co2 profile
VR_fdnorth Forced Diffusion chamber installed near the north soil co2 profile
VR_fdeast Forced Diffusion chamber installed near the east soil co2 profile
VR_soilvue Data from SoilVUE soil moisture and temperature profile probes.
VR_phenocam Camera data as processed by the Phenocam Project - undated infrequently
VR_processed Data from the L1 processed data file
VR_processed3 Data from the L3 processed data file
