Parameters 

Description 

Geom [struct/list] 

Geometry parameters. Can be a structure from GeomStruct or a comma separated list of (hp,ht,rd,...) 

hp [scalar] 

Platform altitude (m) 

ht [scalar] 

Target altitude (m) 

rd [scalar] 

Downrange along spherical earth surface (m) 

season [scalar] 

(Optional) Index to season: 1 - summer (default), 2 - winter 

TOD [scalar] 

(Optional) Index to time of day: 1 - 00:00 to 03:00, 2 - 03:00 to 06:00, 3 - 06:00 to 09:00, 4 - 09:00 to 12:00, 5 - 12:00 to 15:00, 6 - 15:00 to 18:00, 7 - 18:00 to 21:00, 8 - 21:00 to 00:00, 9 - Daily average (default) 

siteID [scalar] 

(Optional) Not required when input geometry is a structure (will override position in input geometry if passed in with a geometry structure). Index to the site for CFLOS computation - see CFLOSSites. If not passed in and input geometry is a list, will use the site closest to [0 0]. 

Return Values 

Description 

val [scalar] 

Probability of cloud free LOS for the input conditions. 

data [struct] 

Structure containing computations for CFLOS for various combinations of platform altitude, target altitude, view angle, and time of day.
