Can a 30m flux tower be a virtual tall tower?
Yes! A tower that measures CO2 mixing ratios
accurately and is sub-sampled for well-mixed,
convective conditions can be representative of
the 1-2km regional convective boundary layer. And
this layer can be resolved in transport models.
This table shows 1997 monthly mean CO2 mixing
ratios from the WLEF tower illustrating
sub-sampling and surface-mid CBL biases, and
comparison to MBL CO2 differences.
