OPAC database (Hess, M., Koepke, P., and Schult, I.:
Optical Properties of Aerosols and Clouds: The Software Package OPAC, B. Am. Meteor. Soc., 79, 831–844, 1998.)
The original database includes only scalar optical properties. Therefore the Mie-calculations have been repeated and the
data including the full phase matrices are available in the format required by the libRadtran RT model. More information and examples of use can be found in
Emde et al., 2010.
