 Synthesis of Top-Down and Bottom-Up Scaling of Regional Terrestrial Carbon Dioxide Fluxes 
Description: Regional exchange of CO2 in the upper Midwest, USA was investigated with several different bottom-up and
top-down methods. With careful calibration, encouraging consistency is seen
from several independent regional flux estimates.

Synthesis of Top-Down and Bottom-Up Scaling of Regional Terrestrial Carbon Dioxide Fluxes
Description: An experiment has been conducted to determine regional-scale fluxes
using both top-down (ABL budgets and atmospheric inversions) and
bottom-up (eddy covariance flux tower aggregation) approaches. The
results show reasonable convergence among methods, but also show
differences in fluxes among forest stands that are significant and not
readily captured by existing land cover products.

Using continental, continuous CO2 observations in a time-dependent global inversion to infer regiona
Description: Simulation of mid boundary layer CO2 mixing ratios from observations
routinely collected at flux tower sites (tower top well-calibrated CO2
mixing ratio, CO2 flux, sensible heat flux and temperature), providing
a means of extending the CO2 measurement to improve the density of
continental measurements in the global network.

Using Inverse Modelling to Investigate Potential IR Measurement Strategies for Constraining the Aust
Description: This study employs a top-down approach to better understanding the carbon cycle. Fourier Transform Spectroscopic trace gas measurements are combined with inverse modelling. Possible measurement locations and strategies in the Australian continent are investigated. This is done by simulating data for the potential measurement locations, and using this simulated pseudodata in inversion studies to determine the additional constraint applied to the source estimate uncertainty in Australia and nearby regions.
