Function Documentation

atmset_()

void atmset_	(	int *	iatmo,
		double *	obslev
	)

The atmospheric model is initialized first before the interpolating functions can be used. For efficiency reasons, the functions rhofx_(), thickx_(), ... don't check if the initialisation was done.

This function is called if the 'ATMOSPHERE' keyword is present in the CORSIKA input file.

The function may be called from CORSIKA to initialize the atmospheric model via 'CALL ATMSET(IATMO,OBSLEV)' or such.

Parameters

iatmo	(pointer to) atmospheric profile number; negative for CORSIKA built-in profiles.
obslev	(pointer to) altitude of observation level [cm]

Returns

(none)
