Mobility Particle Sizer Spectrometer (MPSS)

Since 2012, a custom-made MPSS is working at Chacaltatya to measure size distribution of submicron aerosol.

The submicron aerosol size distribution is measured using a TSI Inc. 3772 Condensation Particle Counter and a custom-made Differential Mobility Analyzer assembled, tested and quality controlled according to EUSAAR recommendations (http://www.eusaar.net/) in TROPOS. The interdependence between the mobility and size of the particle allows converting particle mobility distribution into size distribution, thus the size range of the MPSS extends from about 10 nm to 650 nm. Data are stored with a five-minute time resolution.
