Description

The Environment command allows you to specify the value(s) of specific environmental models as pointed to by a specific attribute. The environmental models include models for rain fade and gaseous absorption.

The Environment commands are applied at the scenario level.

Use this command in conjunction with the Environment_RM GetValue command, which will return a list of attributes, or the properties and choices for a specific attribute.

Example

Set the UseCloudFogModel attribute to true, and set the ceiling, water density and temperature:

Environment * SetValue PropagationChannel.UseCloudFogModel true
Environment * SetValue PropagationChannel.CloudFogModel.CloudCeiling 8000
Environment * SetValue PropagationChannel.CloudFogModel.CloudLiqWaterDensity 456.0 kg/km^3
Environment * SetValue PropagationChannel.CloudFogModel.CloudTemp 273.15 K

Example

To set the rain model and rain outage attributes.

First use the Environment_RM GetValue command with the Choices option on the PropagationChannel.RainModel to get the names of valid Rain Models:

Environment_RM * GetValue PropagationChannel.RainModel:Choices

Crane_1985
ITU-R_P618-10
Script_Plugin
CCIR_1983
Crane_1982
ITU-R_P618-5
ITU-R_P618-8
ITU-R_P618-9

Set the rain model and rain outage attributes:

Environment * SetValue PropagationChannel.UseRainModel true
Environment * SetValue PropagationChannel.RainModel ITU-R_P618-5
Environment * SetValue PropagationChannel.RainModel.SurfaceTemperature 78.6 degC
Environment * SetValue RainOutagePercent 0.03

Example

Enable the Urban Model, load a shapefile, and set options:

The PropagationChannel.UseUrbanTerresPropLossModel.BuildingHeightAttribute depends on the PropagationChannel.UseUrbanTerresPropLossModel.UrbanGeometryFile. When defining these attributes it is best to set any other attributes first, then set the UrbanGeometryFile attribute and then the BuildingHeightAttribute.

Environment * SetValue PropagationChannel.UseUrbanTerresPropLossModel true
Environment_RM * GetValue PropagationChannel.UrbanTerresPropLossModel:Choices
