The objectives of the research are in fact different. The first consists in observing and monitoring the Forni glacier. The second in the identification and characterization of the transport of polluted air masses and air masses rich in atmospheric particles, or dust, anthropogenic and natural reach the site of measurement.

Third, the assessment of the deposition of particulate air pollution on the seasonal melting of snow and ice energy balance and mass of glaciers.

Abstract The CNR1 net radiometer by Kipp & Zonen is for applications requiring research-grade performance. The radiometer measures the energy balance between incoming short-wave and long-wave IR radiation versus surface-reflected short-wave and outgoing long-wave IR radiation. The CNR1 consists of a pyranometer and pyrgeometer pair that faces upward and a complementary pair that faces downward. The pyranometers and pyrgeometers measure short-wave and far infrared radiation, respectively. The CNR1 also includes an RTD to measure the radiometer’s internal temperature and a heater that can be used to prevent condensation.
