Development of UV Sensors to Measure Solar Radiation for Climate Change Research

Scientists from the Institute for Scintillation Materials in Kharkiv, Ukraine, the Lawrence Livermore National Laboratory in Livermore, CA, and the Naval Postgraduate School in Monterey, CA developed UV sensors for solar radiation using advanced zinc selenide-based Schottky photodiodes. These sensors are characterized by high sensitivity, selectivity, radiation stability, reliability and low cost, allowing measurement of both UV radiation intensity and accumulated dose. They enable the collection of critical data to improve the understanding of climate variation, and characterization and evaluation of the effects of global climate parameters such as ozone layer depletion, the “greenhouse effect”, and atmospheric contamination by tropospheric ozone.
In addition, the project provided the basis for mass production of different types of ionizing radiation detectors with world-class performance parameters. The creation of these UV sensors and a prototype dosimeter, with support from a CRDF Global grant, was based on new technology possessed and developed by the project participants. Further improvement of the developed UV-sensors and dosimeter system will facilitate their wide use in climate measurements for stationary and portable weather stations, as well as for biological studies of the effects of solar UV radiation on ecosystems, the oceans of the world, living organisms and humans. The U.S. and Ukraine teams will continue to work to ensure the transfer of the project’s promising science and technology developments to an industrial base which will support future large-scale production of modern equipment for solar UV monitoring and improving climate change research.
