Data: Regional contribution of anthropogenic carbon monoxide in the Asian summer monsoon upper troposphere and lower stratosphere

Wu, Yutian

The dataset includes the key variables that were used to generate the figures in "Regional contribution of anthropogenic carbon monoxide in the Asian summer monsoon upper troposphere and lower stratosphere" submitted.

We study the regional contribution of anthropogenic carbon monoxide (CO) to the Asian summer monsoon upper troposphere and lower stratosphere (UTLS) region by using a tagged CO model experiment. We find that, in climatological mean of 1980-2022, surface emission from South Asia (SAS) makes the largest contribution to the UTLS anthropogenic CO, followed by East Asia (EAS), with smaller contributions from North America, Europe and other regions. Furthermore, for the UTLS CO that is emitted from EAS and SAS, the year-to-year variability is large, and there are years in which the contributions from EAS and SAS are comparable, even though the SAS contribution is always larger. Composite analysis is performed to understand the dynamical mechanism underlying the inter-annual variability.

Notes

data_ac_8regions_JJA.nc includes CO surface flux and CO at 100hPa from 8 subregions. The data are used to generate Figs. 1-3 of the submitted manuscript.
data_ac_EAS_SAS_JJA.nc includes CO surface flux, CO at multiple pressure levels and meteorological variables such as zonal and meridional wind at multiple pressure levels for CO that is emitted from East Asia and South Asia. The data are used to generate Figs. 4-9 of the submitted manuscript.
data_ac_EAS_SAS_Aug.nc is similar to data_ac_EAS_SAS_JJA.nc but during August only. The data are used to generate Fig. 10 of the submitted manuscript.
