Purpose

The Eddy Covariance CO2 flux measurements made at Lauder were specifically instigated for the Endeavour funded Carbonwatch NZ project. Grasslands are likely to be associated with potentially significant carbon sources and sinks, which may be manageable. Currently, New Zealand’s National Inventory Report (NIR) assumes established grasslands have zero net flux. Measurements are vital to estimate realistic fluxes.

• Flux estimates can be added directly to the ‘bottom up’ NIR once they are validated.

• Provide apriori constraints and validation of ‘top down’ regional and national CO2 flux inversions.

• Provide apriori constraints and validation to ‘bottom up’ biochemistry modelling of terrestrial carbon flux.
