Label | Explanation | Data Type |
Input Surface Raster | The input elevation surface raster. | Raster Layer |
Start Date and Time | The start date and time for the analysis. | Date |
End Date and Time | The end date and time for the analysis. | Date |
Input Analysis Mask (Optional) | The input data that defines the locations where the analysis will occur. | Composite Geodataset |
Input Slope Raster (Optional) | The input slope raster that will be used when calculating the output solar radiation. If this input is not specified, the tool will calculate slope values internally from the input surface raster. Providing this value will improve performance, especially if the tool will be run repeatedly or when analyzing larger datasets. | Raster Layer |
Input Aspect Raster (Optional) | The input aspect raster that will be used when calculating the output solar radiation. If this input is not specified, the tool will calculate aspect values internally from the input surface raster. Providing this value will improve performance, especially if the tool will be run repeatedly or when analyzing larger datasets. | Raster Layer |
Output Direct Radiation Raster (Optional) | The output raster representing the direct incoming solar radiation value for each location. The output has units of kilowatt hours per square meter (kWh/m2). | Raster Dataset |
Output Diffuse Radiation Raster (Optional) | The output raster representing the incoming solar radiation that is diffused by the sky, layers of atmosphere, and other surroundings. The output has units of kilowatt hours per square meter (kWh/m2). | Raster Dataset |
Output Direct Duration Raster (Optional) | The output raster representing the duration of direct incoming solar radiation. The output has units of hours. | Raster Dataset |
Time Zone (Optional) | The time zone that will be used for the start and end time. The default is UTC, or Coordinated Universal Time.
| String |
Adjust times for daylight saving time (Optional) | Specifies whether the input time configuration will be adjusted for daylight saving time. This parameter is not applicable for analysis on the Moon.
| Boolean |
Calculate insolation for time intervals (Optional) | Specifies whether a single total insolation value will be calculated for the entire time configuration or multiple radiation values will be calculated for the specified interval.
| Boolean |
Time Interval Unit (Optional) | Specifies the time unit that will be used for calculating solar radiation values over the entire time configuration. This parameter is only available when the Calculate insolation for time intervals parameter is checked.
| String |
Time Interval (Optional) | The value of the duration or time between intervals. The default value is dependent on the interval unit specified. The default value for each of the available units are listed below.
| Long |
Neighborhood Distance (Optional) | The distance from the target cell center for which the output insolation value will be calculated. It determines the size of the neighborhood. The default value is the input surface raster cell size, resulting in a 3 by 3 neighborhood. | Linear Unit |
Use adaptive neighborhood (Optional) | Specifies whether neighborhood distance will vary with landscape changes (adaptive). The maximum distance is determined by the neighborhood distance. The minimum distance is the input raster cell size.
| Boolean |
Diffuse Model Type (Optional) | Specifies the type of diffuse radiation model that will be used.
| String |
Diffuse Proportion (Optional) | The proportion of global normal radiation flux that is diffuse. Values range from 0 to 1. Set this value according to atmospheric conditions. The default value is 0.3 for generally clear sky conditions. | Double |
Transmittivity (Optional) | The fraction of radiation that passes through the atmosphere (averaged overall wavelengths). Values range from 0 (no transmission) to 1 (all transmission). The default is 0.5 for a generally clear sky. | Double |
Target Device for Analysis (Optional) | Specifies the device that will be used to perform the calculation.
| String |
Return Value
Label | Explanation | Data Type | Output Solar Radiation Raster | The output raster representing the total amount of solar radiation received per unit area across the input surface. The output has units of kilowatt hours per square meter (kWh/m2). | Raster |
