Dust event seen from deep space using DSCOVR/EPIC data
Abstract
Abstract: The Deep Space Climate Observatory (DSCOVR) satellite was launched on 11 February 2015 and began observations of both the Earth and the Sun from its Lissajous orbit at the Earth's L1 Lagrangian point, a gravity-neutral position 1.5 million km from the Earth which is four times of the distance from the Earth to the Moon. As a part of the payload of DSCOVR, the Earth Polychromatic Imaging Camera (EPIC) delivers nearly hourly observations of the entire sunlit face of the Earth, with a multispectral imager featuring 10 spectral channels. There was a serious dust event lasting for a few days in North China in May, 2017. For improving the knowledge about the spatial and temporal distribution of the dust event, this paper presents this dust event seen from deep space using the EPIC data. DSCOVR has many unique advantages in wide swath, continuous observation and shows a good result in high latitude areas comparing with polar orbit satellite and stationary satellite, which shows a great potential for monitoring and understanding of global climate change in the future.
