The CLOUD data suite provides per-pixel microphysics and macrophysics to support cloud/climate applications. Typical uses: screening clouds for atmospheric correction, evaluating cloud–radiation interactions, and joint analyses with ocean-color variables (e.g., chlorophyll, Rrs).
Core geophysical variables in this suite include:
• cloud_fraction — Cloud fraction (unitless; range 0–1)
• water_cloud_fraction — Water cloud fraction (unitless; range 0–1)
• ice_cloud_fraction — Ice cloud fraction (unitless; range 0–1)
• cer — Cloud particle effective radius (µm)
• cot — Cloud optical thickness (unitless)
• cwp — Cloud water path (g m⁻²)
• cth — Cloud top height (m)
• ctp — Cloud top pressure (hPa)
• ctt — Cloud top temperature (K)
