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 is largely independent of plot, is to simply substitute good data from an adjacent site for the bad data.
