Product Description:
The Level-3 Continuity Atmosphere Cloud Properties Product (CLDPROP_D3 or CLDPROP_M3) consists daily or monthly 1x1 degree grid values of atmospheric parameters related to  cloud optical and physical properties, such as cloud optical thickness and cloud effective radius, cloud fraction, cloud top properties. Product includes 1D histograms of distributions and 2D joint histograms of one product plotted against the other.
