+====== Preview Solar Radiation ======
+===== Objectives =====
+This dialog allows to preview the solar radiation values that will be used by ENVI-met in the actual simulation. In addition, the user can test the effects of different solar adjustment factors on the radiative fluxes.
+ {{ ::preview_radiation.jpg?nolink |}}
+The left hand side of the dialog shows the following information for the hours form 4 a.m. to 21 p.m. of the first day of the simulation:
+  * Sun height in degrees (0°= horizon)
+  * Sun azimuth in degrees (180°= South)
+  * Shortwave direct radiation in [W/m²] on a **surface perpendicular to the incoming sun** (maximum possible value of direct radiation)
+  * Shortwave direct radiation in [W/m²] on a **horizontal surface**
+  * Shortwave diffuse radiation in [W/m²] on an non-obstructed horizontal surface
+  * Global radiation in [W/m²] on a horizontal surface
+On the right hand side, the last three components are displayed as graphs.
+When opening the dialog, the **adjustment** value shows the actual value stored in the [[solaradjust|[SOLARADJUST] Section]] (or the default value of 1). You can modify this value to see the effects on the radiative fluxes. Press "Update" to refresh the tabular and the graph.
+//**Changing the adjustment value in this dialog has no effect on the actual simulation!** \\
+The intention of this dialog is to provide a quick tool to find out if and how much the solar adjustment should be used to fit the ENVI-met radiation values to your observed values. \\
+**After you have found an appropriate value, you must use the [[solaradjust|[SOLARADJUST] Section]] in the Configuration File in order to use this value in a simulation**. \\
+All changes done in this dialog will be lost after closing the dialog! //
