Structure containing variances of SCA products bin per bin id field name definition 0 extinction_variance binary double size: 8 Variance of the particle extinction coefficient retrieved by the SCA in this bin. Missing value: -1. unit: "m^-2" 1 backscatter_variance binary double size: 8 Variance of the particle backscatter coefficient retrieved by the SCA in this bin. Missing value: -1. unit: "m^-2 sr^-2" 2 lr_variance binary double size: 8 Variance of the particle lidar ratio retrieved by the SCA in this bin. Missing value: -1. 3 ber_variance binary double size: 8 Variance of the particle lidar ratio retrieved by the SCA in this bin. Missing value: -1. 4 rayleigh_heterogeneity_index binary double size: 8 Index that characterizes the variability of the Rayleigh useful signal within one BRC. It is defined as the standard deviation of the Rayleigh useful signal within a BRC with respect to the Poisson noise. 5 mie_heterogeneity_index binary double size: 8 Index that characterizes the variability of the Mie useful signal within one BRC. It is defined as the standard deviation of the Mie useful signal within a BRC with respect to the Poisson noise. 6 lod_variance binary double size: 8 Variance of the LOD retrieved by the SCA in this bin. Missing value: -1. 7 processing_qc_flag binary int8 size: 1 QC information about processing (1=data valid, otherwise 0). Bit 1: Extinction, 2: Backscatter, 3: BER, 4: Mie SNR, 5: Rayleigh SNR, 6: Extinction error bar, 7: Backscatter error bar, 8: Cumulative LOD 8 cloud_mask binary int8 size: 1 Flag indicating the cloud contamination of each height bin (i.e. derived backscatter from AMD exceeding a defined threshold). Set to 1 for cloud contaminated bin, otherwise 0.
