Innovations and Benefits
The measurement of global solar irradiance in the UV region of the spectrum is fundamental for the monitoring of some important indicators for the state of the plant, animal and human health environment.
The instrument is able to measure the solar spectrum every minute on 10-12 wavelengths from 290 nm to 400 nm, with a spectral resolution of less than 1 nm. From the measurements of the F_RAD radiometer it is possible to derive, for example, the value of the UV index and the content of the stratospheric columnar ozone.
The compact version of the instrument is able to measure the solar irradiance for a discrete number of wavelengths, chosen according to the sector of application. The calibration and maintenance of the instrument can be carried out every two years. Its use does not require qualified personnel.
Use
The tool is available in two versions, depending on the environment in which it is used and the purposes for which it is intended. In science, the tool is able to operate in remote conditions and in hostile environments. In this context, it can be used for the measurement of UV solar irradiance for research on climate and on the physics of the atmosphere.
In the framework of environmental control related to public health, F-RAD is able to estimate the UV index.
The use can also be extended to the monitoring of UV radiation in relation to its effects on agricultural production, on the health of plants and of marine and lake environments.
Applications and ongoing Activities
Several campaigns to measure UV solar irradiance and Total Columnar Ozone were carried out with the F-RAD version operating stand-alone. For this purpose, three different instruments have been created, set up for measurements in a remote and hostile environment.
In particular, the measurement campaigns were carried out at: the Mario Zucchelli summer station (Antarctica, Ross Sea) from November 2009 to May 2013; Concordia Dome station from January 2012 to May 2013; at ARPA Aosta (June 2010); ARPA Lazio (2010-2011).
