We validate the newly established MTP-5HE temperature profilers for EPA with radiosoundings and our research codes. The observation data from MTP-5HE are used to study the evolution of the atmospheric temperature profile near ground and the variations of concentration of PM10 when temperature inversion layers occur. The three-dimensional IMS Lagrangian trajectory model has been employed to construct a trajectory climatology for the East Asia region. These trajectory results were compared with the hourly ambient PM10 concentrations from a network of 72 surface air quality stations operated by the Taiwan EPA to determine the transport of pollutants and downstream impacts in the East Asia region.
