Solar Uv Irradiation Monitoring in Bulgaria Using Narrow-Band Digital Sensors and Open-Source Influxdb Database

Abstract

The global climate change in the recent years has increased the interest to atmospheric irradiation monitoring in wider format. Additionally to Gamma-ray and X-ray sensors, UV-C, UV-B and UV-A sensing systems has been developed to respond to the human expectations about sustainable life and to prevent them from hostile factors. The deeper penetration of UV sensor equipment and dense disperse of monitoring points will improve further the accuracy of measurements, accuracy of forecasting and will convince the citizens in the responsibility of researchers and their work. This work presents UV sensing equipment developed for remote monitoring. Solutions include complex system of narrow band UV sensors, datalogging units, wi-fi communication devices, solar PV charging and Li-Ion energy storing equipment. Most of the components and software technologies are based on opensource platforms and approaches as well as internet-shared results. The analysis of results from 3 UV sensor systems already installed in 3 high-mountain monitoring locations reveals local UV spectral variations. The performance of UV sensors has been evaluated. The collected database during two-year field measurements is prepared for training and development of algorithms for short-term UV forecasting.
