This
presentation describes in-situ atmospheric CO2 measurements at Waliguan
Observatory (WLG, 36°17'N, 100°54'E, 3816m asl) since 1994, together with 5-day isobaric
back trajectory analysis. We also use the
Hybrid Single-Particle Lagrangian Integrated Trajectory (Hysplit-4) transport/diffusion
model to simulate the CO2 variation at WLG in January 1999 and
compared with observations. A case study for polluted air mass transport event with
a short-term elevated CO2 has been conducted to further investigate the
impact of source, sink and long-range transport of atmospheric CO2.
