+ | ====== 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. | ||
+ | |||
+ | {{ :: | ||
+ | |||
+ | 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 " | ||
+ | |||
+ | // | ||
+ | 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! // | ||
