Emulating atmosphere-ocean and carbon cycle models with a simpler model, MAGICC6 – Part 2: Applications
atmosphere-ocean carbon cycle models a simpler model MAGICC6
2011/2/25
Intercomparisons of coupled atmosphere-ocean general circulation models (AOGCMs) and carbon cycle models are important for galvanizing our current scientific knowledge to project future climate. Inter...
Emulating coupled atmosphere-ocean and carbon cycle models with a simpler model, MAGICC6 – Part 1: Model description and calibration
coupled atmosphere-ocean carbon cycle models a simpler model MAGICC6
2011/2/25
Current scientific knowledge on the future response of the climate system to human-induced perturbations is comprehensively captured by various model intercomparison efforts. In the preparation of the...
Analysis of 13C and 18O isotope data of CO2 in CARIBIC aircraft samples as tracers of upper troposphere/lower stratosphere mixing and the global carbon cycle
13C and 18O isotope data CO2 CARIBIC aircraft samples the global carbon cycle
2010/9/21
The project CARIBIC (http://caribic-atmospheric.com) aims to study atmospheric chemistry and transport by regularly measuring many compounds in the free troposphere and the upper troposphere/lowermost...
What can be learned about carbon cycle climate feedbacks from the CO2 airborne fraction?
carbon cycle climate the CO2 airborne fraction
2010/8/25
The ratio of CO2 accumulating in the atmosphere to the CO2 flux into the atmosphere due to human activity, the airborne fraction AF, is central to predict changes in earth's surface temperature due to...
Characterization of Tropospheric Emission Spectrometer (TES) CO2 for carbon cycle science
Tropospheric Emission Spectrometer CO2 carbon cycle science
2010/8/13
We present carbon dioxide (CO2) estimates from the Tropospheric Emission Spectrometer (TES) on the EOS-Aura satellite launched in 2004. For observations between 40° S and 45° N, we find about 1 degree...
Simulating the global atmospheric black carbon cycle: a revisit to the contribution of aircraft emissions
global atmospheric black carbon cycle aircraft emissions
2009/3/10
The black carbon (BC) burden of the upper troposphere and lowermost stratosphere (UTLS) is investigated with the general circulation model (GCM) ECHAM4. The special focus is the contribution of aircra...
Arguments on Oceanic Carbon Cycle of IPCC Assessments——A Test Using δ13C Budgets
IPCC CO2 budget δ13C isotope fractionation
2010/2/21
By comparing the global carbon cycle of the IPCC assessment reports in 1990, 1996, 2001 and 2007, it was found that despite the estimated sizes of the main carbon reservoirs and the fluxes between the...
