Existent SPM sampler is so big and heavy that it is not suitable to measure vertical SPM distribution. Small SPM sampler which can hang from spring of a captive balloon has been developed by author. This sampler that runs on batteries consists of a filter holder for personal dust sampler and a small vacuum pump, and weighs about 700g. Quantity of SPM collected on the filter is measured from the micrograph captured by the field emission scanning electron microscope (FE-SEM). SPM number, temperature, relative humidity and wind velocity profiles were measured using this small SPM sampler and the captive balloon at the riverside and near the highway. SPM number profile up to 50m in height near the highway shows the difference of the SPM distribution.
