When tried to publish the processed data
- “TAU” (corrected momentum flux) was all zero after 2016. The variable was not being collected after 2016. BB replaced all 0 values after 2016 with -9999, Ameriflux’s preferred fill value.
- Incoming shortwave (light) radiation and incoming PAR (photosynthetically active radiation) in 2008 and 2009 were outside of Ameriflux's absolute limits. They also showed a clearly different pattern than later years.
- Net radiation was also too high, but this was because of the problem with incoming shortwave.
- Ameriflux suggested a linear correction. BB’s approach will likely be to fit the problem data against good data from an adjacent (~ 300m away) plot to acquire a correction factor. A simpler but less robust alternative, given that incoming shortwave and incoming PAR are largely independent of plot, is to simply substitute good data from an adjacent site for the bad data.
