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.

Carbon isotope evidence for the latitudinal distribution of air-sea gas exchange
Description: The
air-sea gas exchange rate is important for modeling and verifying ocean CO2
uptake, but remains subject to considerable uncertainty. The widely assumed
quadratic or cubic dependence of the exchange rate on windspeed together with
the latitudinal pattern of mean windspeed implies that exchange is much faster
at high compared with low latitudes. This should affect the pattern of ocean
uptake of bomb carbon-14 as well as the rate of decline of and latitudinal
gradients in atmospheric Δ14CO2. We evaluate the
constraints on the windspeed dependence of the exchange rate offered by
available isotopic measurements, discuss the major uncertainties, and suggest
observational strategies to reduce these uncertainties.

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.
