Data Streams:

CodeDescription
BA_met Micromet data from the Bouldin Alfalfa site recorded by a CR1000 as 30min averages of 10sec samples.
BA_flux 30min averages of high frequency flux data from Licor GHG files
BA_cam Digital number data from Pheoncamera at Bouldin Alfalfa
BA_arable Hourly met data from an Arable Mark device. Raw times are in UTC, hourly averages with the time at the beginning of the averaging period beginning 20190401 changed to 30min data PST at end of averaging period. - stored in PST at end of averaging period.
BA_fd Soil respiration data at BA from the second generation Forced Diffusion chamber from Eosense. The raw data is collected at 5min intervals and averaged to 30min values. The chamber is located under the tower. Alfalfa was removed from inside the chamber.
BA_processed Fluxes and derived values from Level 1 processing
BA_processed3 Gap filling and partitioned data from Level 3 processing
BA_fdb Soil CO2 flux from an Eosense Forced Diffusion Chamber, 2nd chamber added under BA tower
BA_irtsr Surface temperature from two Apogee IRT sensors one pointing north and the other south at a 45 deg inclination. These are recorded at both 2Hz and 30min averages for surface renewal by Kevin Tu.
BA_edgeli75 Upper sonic and CO2/H2O data from BA Edge tower
BA_bncrli75 Upper sonic and CO2/H2O data from BA Bouncer tower
BA_bncr23x 30-min averages of met data from BA Bouncer CR23X
BA_edgecr6 Lower sonic at BA Edge tower
BA_bncrcr6 Lower sonic at BA Bouncer tower
BA_edge23x 30-min averages of met data from BA Edge CR23X
BA_adexcr1k 30-minute averages of data from CR1000 on the main BA tower measuring the upper and lower sonics
BA_adextrh 30-minute averages of temperature and RH data from the main BA met CR1000
BA_edgetrh 30min averages from 10sec lower and upper T/RH readings at BA Edge tower
BA_bncrtrh 30min averages from 10sec lower and upper T/RH readings at BA Bouncer tower
