Structure containing variances of SCA-MLE BRC-level products bin per bin in Rayleigh scale. id field name definition 0 extinction_variance binary double size: 8 Variance of the particle extinction coefficient retrieved by the SCA-MLE 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-MLE 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-MLE in this bin. Missing value: -1. 3 ber_variance binary double size: 8 Variance of the particle lidar ratio retrieved by the SCA-MLE in this bin. Missing value: -1. 4 sr_variance binary double size: 8 Variance of the particle scattering ratio retrieved by the SCA- MLE in this bin. Missing value: -1. 5 lod_variance binary double size: 8 Variance of the particle scattering ratio retrieved by the SCA- MLE in this bin. Missing value: -1. 6 slod_variance binary double size: 8 Variance of the slant LOD retrieved by the SCA-MLE in this bin. Missing value: -1. 7 cloud_mask binary uint8 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.
