Terra (MODIS) – cloud properties

Available properties: physical and radiational properties, including information on the transitional phases (ice – water, clouds – snow), radius and dispersion of cloud particles, cloud optical thickness, cloud top temperature, cloud shadowing effects, cloud height, cloud phase, cloud fraction at day and night as well as other parameters.

The full list of available parameters is given below. For each parameter there are additional characteristics separated by semicolon (;). The characteristics apply to a single cell of regular latitude-longitude grid with spatial resolution of 1°×1°.
