The OPC, manifactured by FAI, permit a - Characterization of the temporal trends of the particulate matter granulometric distribution as a support and integration to information about air quality - Real-time estimation of the PM1, PM2.5, PM10, TPS mass concentration of the airborne particulate matter. Main features - Measurement principle: laser scattering on elliptical mirror - Optical channels: 8 optical channels with thresholds having lower limits [µm]: 0.28, 0.4, 0.5, 0.7, 1.1, 2.0, 3.0, 5.0 - Sampling type: The instrument gives counts per minute, or counts per liter for each optical channel - Dimensional sensitivity: 0.28 µm (50 ± 10% count efficiency)

At Askole Station, a DQA035 electric rain gauge was installed. This sensor is manufactured by Lsi-Lastem (Italy) company. Rain gauge is a sensor to measure rain fall.
-
25 Halocarbons relevant for climate issues will be analysed in grab samples collected weekly.
-
At Askole Station, a CM6B Pyranometer was installed. This sensor is manufactured by Kipp&Zonen (The Netherlands) company. The CM6B Pyranometer is suitable for the routine measurement of incoming global solar radiation (0.3 to 2.8 µm spectral range), diffuse sky irradiance measurements, and surface reflected solar radiation measurement research.

Within the Ev-K2-CNR Project SHARE on February 2010 an Automatic Weather Station (AWS) has been installed on the debris-free surface of the Changri Nup Glacier (Nepal, Himalayas) at 5,700 m asl. The AWS is acquiring meteorological data and energy fluxes (incoming and outgoing) at the glacier surface.
-
At Askole Station, a CombiSD DNA022 sensor (LSI-Lastem, Italy) was installed. The CombiSD combines sensors for measuring both wind speed and direction in a single instrument.

At the end of March 2006 a Cimel CE-318 sunphotometer was installed. It provides a characterization of aerosol optical and microphysical properties of the air column above the station. These measurements allow to follow the time evolution of the aerosol optical depth (AOD) at eight wavelengths, plus other properties as single scattering albedo (SSA, fundamental in computing the aerosol effects on solar radiation), particle size distribution (SD, fundamental in assessing the ABC effects on formation and lifetime of water vapor clouds) and refractive index.
