The "MASS"

This website describes the application of an innovative approach for measuring airborne particulate matter. Results of dust measurements in three areas through the "MASS" (Mobile Air Sampling System) are presented. The MASS is an instrument designed, assembled and patented by CISMA. This is a device designed to be mounted on a car, intended for sampling of fine particles and coupled with a GPS antenna for georeferincing. The instrument is based on an opticall particle-counter and can provide one measurement record of dust concentration every 6 seconds for 15 granulometric classes between 0.3 and 20 µm.

The figures represent some measurement campaigns for areas the of Bolzano / Merano, Trento, Rovereto and Verona. The results are superimposed cartography and refer to the gravimetric classes which are conventionally taken into account for the analysis of air quality: PM10, PM2.5 and PM1; concentrations are expressed as µg/m³. Values reported should be intended as instantaneous concentrations.

In order to correctly view the maps in your browser yo'll need to install the version 7 (or above) of the "shockwave flash" plugin.

The navigation within the map can be performed by means of the "zoom" and "pan" buttons, which are positioned near the lower edge of the display area. In addition, the "pan" command can be performed by dragging with your mouse over the map. A mouse click on a measure point will activate a default 4x zoom centered on the point. To view the data for a certain location just place the mouse cursor over the circle. A screen resolution of at least 1024x768 for a full view is recommended.
