WSMRCn2

MATLAB

Cn2 = WSMRCn2(h,ModelType,[GroundAlt])

Description

Returns the value of the WSMR turbulence profile given altitude above ground level in meters. If input altitude is specified as meters above sea level, the ground altitude can optionally be specified. The model identified as '80%WorstSpring' is the 80th percentile worst Cn2 for springtime measurements collected between 1000-1400 local time at WSMR.

Parameters

Parameters	Description
h [vector]	Altitude above ground/sea level (m)
ModelType [string]	Model descriptor for turbulence condition. Default is '50%Day' if not specified. Valid inputs are: '10%Best', '50%Day', '50%Night', '80%WorstSpring', '90%WorstDay', 'Night', and 'Average'
GroundAlt [scalar]	(Optional) Ground altitude above sea level if input altitude is meters above sea level. Values less than GroundAlt will be set to GroundAlt for evaluation of the model.

Return Values

Return Values	Description
Cn2 [vector]	Index of refraction structure coefficient (${m}^{-2/3}$)

Examples

>> Cn2 = WSMRCn2([0:2000],'80%WORSTSPRING');

Use "80% Worst, Spring" turbulence model

>> Cn2 = WSMRCn2([0:2000],'80%WORSTSPRING',1000);

Same as example above, but input is altitude ASL and ground altitude is 1000 m.
