abstract = {Atmospheric concentrations of the greenhouse gases carbon
dioxide and nitrous oxide haveincreased substantially
because of human activities. However, their sources in South
Asia,which contribute strongly to the accelerating global
growth of carbon dioxide and nitrousoxide, are poorly
quantified. Here, we present aircraft measurements with high
temporal andvertical resolution up to 20 km during the Asian
summer monsoon where rapid upwardtransport of surface
pollutants to greater altitudes occurs. Using Lagrangian
model simulations, we successfully reconstruct observed
carbon dioxide profiles leading to an improvedunderstanding
of the vertical structure of carbon dioxide in the Asian
monsoon region. Weshow that spatio-temporal patterns of
carbon dioxide on the Indian subcontinent driven byregional
flux variations rapidly propagate to approximately 13 km
with slower ascent above.Enhanced carbon dioxide compared to
the stratospheric background can be detected up to20 km. We
suggest that the propagation of these signals from the
surface to the stratospherecan be used to evaluate transport
models and assess carbon dioxide fluxes in South Asia.},
