UV Data Record Release 1, daily dose, UVA range (315-400 nm) - Multimission

This product gives the accumulated dose of solar ultraviolet radiation for a given day. The solar spectral irradiance arriving on a horizontal Earth's surface at a given location and time of day is integrated over the UV-A wavelength range (315 - 400 nm) to yield the dose rate. The dose rates are calculated with half-hourly intervals during the sunlit part of the day and then integrated over time to yield the daily (accumulated) dose. Input total column ozone data are obtained from GOME-2/Metop measurements while daily cloud data are collected from multiple overpasses of AVHRR/3 instrument onboard both Metop and NOAA satellites.
