Optical properties of mineral dust particles observed over Warsaw with Aerosol Depolarization Raman Lidar in 29-30 June 2019

This dataset comprises the vertically resolved optical properties of mineral dust particles observed over Warsaw with Aerosol Depolarization Raman Lidar on 29-30 June 2019.The data set consist of 3 files:Optical_properties.rar – a compressed archive with 165 NetCDF format files (99 b- and 66 e-files) consisting of vertical profiles of optical properties of atmosphere obtained for the period starting from 00:05 UTC 29th June 2019 and ending at 23:55 UTC 30th June 2019. File format is fulfilling the EARLINET database requirements. A b- file contains following vertically resolved variables: altitude, particle backscattering coefficient, volume depolarization ratio and particle depolarization ratio. All profiles have 357.5 m vertical smoothing applied and are provided at a certain wavelength (355 nm, 532 nm or 1064 nm) given in the file name. An e-file contains following vertically resolved variables: altitude, particle extinction coefficient, particle backscattering coefficient, volume depolarization ratio and particle depolarization ratio. All profiles have 757.5 m vertical smoothing applied and are provided at a certain wavelength (355 nm or 532 nm) given in the file name. More details about the station location and altitude can be found in every file in the Global attributes section.Water_Vapour.rar – a compressed archive with 12 ASCII format files consisting of vertical profiles of water vapor mixing ratio obtained for the period starting from 00:05 UTC 29th June 2019 and ending at 23:55 UTC 30th June 2019. The file contains following vertically resolved variables: lidar-derived altitude (Altitude_Lidar_[m]) and Water Vapour Mixing Ratio (WVMR_from_lidar_[g/kg]), as well as radiosonde-derived altitude (Altitude_Radiosonde_[m]) and Water Vapour Mixing Ratio (WVMR_from_Radiosonde_[g/kg]). Both height vectors are independent and starting from 183.5 m for lidar and from 3.75 m for radiosonde. The vertical resolution of both WVMR profiles is 7.5 m. The radiosonde data measured at WMO station in Legionowo (station number: 12374) were linearly interpolated between each measurement point to have the same resolution as lidar data.Backscatter_separation.rar – a compressed archive with 31 ASCII format files consisting of vertical profiles of mineral dust separation results obtained for the period starting from 00:05 UTC 29th June 2019 and ending at 23:55 UTC 30th June 2019. The file contains following vertically resolved variables: Altitude, Backscattering_dust and Backscattering_non_dust (both obtained using one-step separation), Backscattering_dust_coarse, Backscattering_dust_fine, and Backscattering_non_dust_2 (obtained using two-step separation). The provided backscattering profiles are at 532 nm with 357.5 m vertical smoothing applied. ATTENTION: We offer a free access to this dataset.
