Abstract
Measurements with two unique spectrometric aerosol Raman lidars located in the United Kingdom
(51.75 °N; 0.24 °W) and the Republic of Korea (35.23 °N;126.84 °E) will be conducted during EarthCARE overpasses to validate the aerosol and cloud profile products obtained from ATLID observations.
The Lidar Spectroscopy Instrument (LiSsI, Tesche et al., 2018) at the University of Hertfordshire (UH), Hatfield, UK, and the Multiwavelengths Raman Spectrometer Lidar in East Asia (MRS.LEA, Tatarov et al., 2012, Noh et al., 2016), at the Gwangju Institute of Science and Technology (GIST), Gwangju, Republic of Korea, are globally unique in their capability to enable multiwavelength spectrometric profiling of Raman scattering and depolarisation of gaseous and particulate pollution.
The parameters of relevance for the validation of ATLID data products that will be delivered from measurements with LiSsI and MRS.LEA are profiles (all at 355 nm) of the attenuated backscatter coefficient (up to an altitude of at least 30 km), the aerosol backscatter and extinction coefficient, the lidar ratio and the particle linear depolarisation ratio. Both instruments also provide the base and top heights of aerosol layers as well as the base height of optically thick cloud layers and the base and top heights of optically thin cloud layers.
