+The user can choose between the following schemes:
+
+'' 'constant' ''
+
+A constant net radiation at the surface is prescribed (see [#net_radiation]).
+
+
+'' 'clear-sky' ''
+
+A simple clear sky model is used to calculate the radiation fluxes at the surface (shortwave incoming, shortwave outgoing, longwave incoming, longwave outgoing) and consequently the net radiation at the surface. This scheme required the setting of [#albedo albedo], [#day_init day_init], [#lambda lambda], [wiki:doc/app/inipar#phi phi], [#time_utc_init time_utc_init].
