Zusammenfassung |
We present a global dataset of CO2 emissions and O2 uptake
associated with the combustion of different fossil fuel types. To derive
spatial and temporal patterns of oxygen uptake, we combined high-resolution
CO2 emissions from the EDGAR (Emission Database for Global Atmospheric
Research) inventory with country level information on oxidative ratios,
based on fossil fuel consumption data from the UN energy statistics
database. The results are hourly global maps with a spatial resolution of
1°×1° for the years 1996–2008. The potential influence of spatial
patterns and temporal trends in the resulting O2/CO2 emission
ratios on the atmospheric oxygen signal is examined for different stations
in the global measurement network, using model simulations from the global
TM3 and the regional REMO transport model. For the station Hateruma Island
(Japan, 24°03' N, 123°48' E), the simulated results are also
compared to observations. In addition, the possibility of signals caused by
variations in fuel use to be mistaken for oceanic signals is investigated
using a global APO inversion. |
