+Parameter to consider solution and curvature effects on the equilibrium vapor pressure of cloud droplets.
+
+This parameter only comes into effect if Lagrangian cloud droplets are used (see [#cloud_droplets cloud_droplets]) and if the droplet radius is smaller than ''1.0E-6'' m. In case of '''curvature_solution_effects''' = ''.T.'', solution and curvature effects are included in the growth equation of droplets by condensation. Since in this case the growth equation is a stiff o.d.e, it is integrated in time using the Rosenbrock method (see Numerical Recipes in FORTRAN, 2nd Edition, p.731). If the droplet radius is larger or equal ''1.0E-6'' m, solution and curvature effects are neglected and the growth is calculated by a simple analytic formula (as for '''curvature_solution_effects''' = ''.F.'').\\\\
+'''Attention:''' '''curvature_solution_effects''' = ''.T.'' may significantly increase CPU time of jobs.
