The Point Cloud of Cloud Points (PCCP) value-added product is essentially a set of three-dimensional positions representing the locations of cloud features captured by stereo pairs. A stereo pair is a pair of cameras that take synchronized pictures with overlapping fields of view (FOV).
Currently, three stationary ARM stereo pairs are positioned around the Southern Great Plains Central Facility. Thousands of cloud features can be instantly reconstructed in each stereo pair’s FOV, which covers an area of tens of square kilometers.
Cloud-base and cloud-top heights, the structure of cloud boundaries, and cloud-level horizontal velocities can be extracted from the PCCP product.
You can use this Python script to plot instantaneous PCCP data.
PCCP field campaign data sets are also available. A pair of ARM cloud digital cameras is being used for mobile deployments.
