29	! History:
30	! Jul 2007 - A. Bodas-Salcedo - Initial version
31	! Jul 2008 - A. Bodas-Salcedo - Added definitions of ISCCP axes
32	! Oct 2008 - H. Chepfer - Added PARASOL_NREFL
33	! Jun 2010 - R. Marchand - Modified to support quickbeam V3, added ifdef for
34	! hydrometeor definitions
35	! May 2015 - D. Swales - Tidied up. Set up appropriate fields during initialization.
36	! June 2015- D. Swales - Moved hydrometeor class variables to hydro_class_init in
37	! the module quickbeam_optics.
38	! Mar 2016 - D. Swales - Added scops_ccfrac. Was previously hardcoded in prec_scops.f90.
