Data Streams:
| Code | Description |
|---|---|
| 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 |
| BA_sentek | Soil data from the 1m long Sentek probe connected to the Arable. Original data is hourly average with UTC timestamp at the beginning of the averaging period. The times have been adjusted back 7.5 hours to the middle of the averaging period in local standard time and linearly interpolated to 30min intervals. |
