MISR CFbA

Cloud Fraction by Altitude

The MISR Level 3 Products are global or regional maps of select parameters from the Level 2 products and associated covariances reported on various geographic grids depending on the data product. Parameters from multiple orbits are combined to make complete Level 3 global maps at daily (D), monthly (M), quarterly (Q), and yearly (Y) time scales and regional maps associated with field campaigns at daily and monthly time scales.

The CFbA product provides the frequency of cloud occurrence partitioned into different cloud top height bins at a global and monthly scale.
