Combined UV Irradiance from TOMS-OMI satellite and UVMRP ground measurements across the continental U.S.

摘要

Surface ultraviolet (UV) observations can be obtained from satellite or ground observations. This study uses data fusion to combine the advantages from both sources of observations, aiming at achieving a better estimate of surface UV. In this study, ensemble methods were used to estimate the covariances, which are the most important components in data fusion. The combined UV observations not only have the same coverage as satellite data, but also improve their regional accuracy around the ground observatories.
