PACE OCI Level-3 Global Mapped Cloud Mask Data, version 3.2

The Cloud Mask identifies whether pixels are cloud-covered or not. This is important because algorithms to determine cloud properties should only run on cloudy pixels, and other algorithms that require clear-sky pixels need to screen clouds out. In practice, users apply cloud_flag for strict cloud removal and cloud_flag_dilated when they want a conservative mask that reduces cloud-edge artifacts in downstream products (e.g., Rrs, chlorophyll). The CLDMASK is used operationally as the "cloud and cloud-adjacent" screen. Core geophysical variables in this suite include: - cloud_flag - Cloud mask (bitmask; identifies cloud-contaminated pixels) - cloud_flag_dilated - Cloud or cloud-adjacent pixel mask (bitmask; includes surrounding pixels)
