A Paleo Perspective on the Ocean's Role in the Carbon Cycle Description: The ocean has a dominant influence on carbon dioxide in the atompshere,
and ocean processes change slowly (centuries to thousands of
years). Paleo reconstructions of the large natural changes that
have occurred in the past provide a way to understand the ocean's role.

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. Author's Names: K.J. Davis, A.R. Desai, and coauthors Filesize: 48 bytes Added on: 03-Oct-2005 Downloads: 47 Home Page | Comment on Proceeding | Details
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.

Effect of Enriched CO2 on Rice Under Open Top Chamber (OTC) Condition in Nepal Description: Rise is the most important crop for majority of farmers of Nepal both
in terms of it contribution to the national economy and
employment. The objective of this study was to evaulate the
effect of the elevated CO2 on rice crop under open top chambe (OTC)
condition.

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. Author's Names: Ankur R Desai Filesize: 621.91 Kb Added on: 26-Sep-2005 Downloads: 52 Home Page | Comment on Proceeding | Details
IMPACT OF ELEVATED CO2 ON THE FOOD PRODUCTION OF NEPAL Description: The three cereal crops rise, maize and wheat cover over 75% of the
total food production of Nepal. All the three crops rise, maize
and wheat showed increased yield with doubling the CO2 level but also
showed a declining tendecny at the elevated temperature. Among
the three crops, maize was the most affected by the rise in
tempuerature although increased CO2 level could increase the crop yield.

Measurements and Models of Atmospheric Potential Oxygen (APO) Description: Measurements of atmospheric O2/N2
ratios and CO2 concentrations can be combined to form the tracer
Atmospheric Potential Oxygen (APO), reflecting primarily ocean biogeochemistry
and atmospheric circulation. Building on the work of Stephens et al. [1998], we present a new set of APO observations including shipboard collections from the
equatorial Pacific. Our data show a
smaller interhemispheric gradient than observed in past studies and a
substantial APO maximum around the
equator. Following a modeling approach
developed by Gruber et al. [2001], we
compare these observations with APO fields
generated by a set of oceanic and atmospheric models. Overall, our model results agree well with
observations, but small differences suggest that modeled north-south transport
may be too vigorous, air-sea fluxes may be too coarsely resolved in some
regions, and seasonal trapping of surface fluxes may be excessive in some model
locations. Author's Names: Mark Battle Filesize: 0 bytes Added on: 26-Sep-2005 Downloads: 53 Home Page | Comment on Proceeding | Details
A Bayesian synthesis inversion of the global carbon cycle: How observations reduce uncertainties Description: Global-scale observations of CO2 concentrations and fluxes are
assimilated by a simple carbon cycle model in order to produce full
probability density functions of 4 key carbon cycle parameters using
the Markov Chain Monte Carlo technique. Future sink uncertainty
is estimated under the S550 stabilization scenario, and the utility of
additional flux observations to reduce sink uncertainty is analyzed.

OBSERVATIONAL DATA SCREENING TECHNIQUE USING ATMOSPHERIC TRANSPORT MODEL AND INVERSE MODEL IN ... Description: We
have developed a new data screening technique using an atmospheric transport
model and an inverse model. Using this technique, we can use original (not
smoothed) observational data for the inversion method. This means that we can
enlarge the number of observational data for inversion method and we can
estimate carbon dioxide (CO2) flux history consistently in long period
in accordance with the number of the observational sites.

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.
