release()

subroutine prtprpmodule::release ( class(prtprptype), intent(inout)  this, integer(i4b), intent(in)  ip, real(dp), intent(in)  trelease  )

Releasing a particle entails validating the particle's coordinates and settings, transforming its coordinates if needed, initializing the particle's initial tracking time to the given release time, storing the particle in the particle store (from which the PRT model will later retrieve it, apply the tracking method, and check it in again), and accumulating the particle's mass (the total mass released from each release point is calculated for budget reporting).

Parameters

[in,out]	this	this instance
[in]	ip	particle index
[in]	trelease	release time
