The cloud height at optical centroid is a height within the cloud, near the optical thickness center of the cloud. There is also a standard name for air_pressure_at_cloud_optical_centroid.

Height is the vertical distance above the surface. The cloud height at optical centroid is a height within the cloud, near the optical thickness center of the cloud. There is also a standard name for air_pressure_at_cloud_optical_centroid.

Height is the vertical distance above the surface. The cloud height at optical centroid is a height within the cloud, near the optical thickness center of the cloud. The optical thickness is the integral along the path of radiation of a volume scattering/absorption/attenuation coefficient. The radiative flux is reduced by a factor exp(-"optical_thickness") on traversing the path. A coordinate variable of radiation_wavelength or radiation_frequency can be specified to indicate that the optical thickness applies at specific wavelengths or frequencies. There is also a standard name for air_pressure_at_cloud_optical_centroid.
