  abstract = {{During the Indian Ocean Experiment (INDOEX) Intensive Field Phase, 17
superpressure balloons drifting at lower tropospheric levels were
launched from Goa to sample the motion and meteorological
characteristics of polluted air masses originating from the Indian
subcontinent. The mass flow, as expected, is attracted to the
Intertropical Convergence Zone (ITCZ), which is reached in about 7 days.
Successive trajectories show evidence of shifts in the flow regime,
consistent with Meteosat-5 imagery and illustrative of the Madden-Julian
oscillation. Balloons also show evidence of coastal anticyclonic
circulations off the western coast of India, linked to both the
orography of the Gh{\^a}ts and the diurnal coastal wind mesoscale wind
systems. These mesoscale circulations may be important in the transport
of anthropogenic or mineral pollutants across the coast. The
meteorological data gathered on board the balloons were systematically
compared with European Centre for Medium-Range Weather Forecasts (ECMWF)
analyses interpolated in time and space at the balloons' successive
locations every half-hour. The agreement is generally good in terms of
wind velocities, temperature, and humidity. However, above the marine
boundary layer, balloon data seem to indicate a cold bias of analyzed
temperatures and a northeasterly bias of horizontal winds. The
underestimation of variability in the analyzed winds can be partly
explained by mesh size smoothing in the analysis system.
