5579	2021-11-17	Vaira Forced Diffusion West	Removed	Lab none	Removed from Vaira West due to bad CO2 concentration readings
5373	2021-07-13	Vaira Forced Diffusion West	Maintenance	Vaira Forced Diffusion West	Performance check done. Referenced to 400ppm. Average Flux: -0.0, 0.08 STDEV Average ATM: 610.7ppm, 49.6C Average Soil: 609.8ppm, 49.8C
5218	2021-03-17	Lab none	Installed	Vaira Forced Diffusion West	Installed at Vaira to replace sn FD20190028 for possible use at Hill Slough.
5200	2021-03-15	Factory none	Returned	Lab none	Returned from Eosense. It was sent in for zero CO2 readings but Eosense reported that it seemed to be reading correctly. It was calibrated from CO2 concentration and CO2 flux.
