SEET Particle Fluence

Computes the total fluence (i.e., the total flux of all particulates integrated over time). Valid for vehicles whose central body is earth.

Available for these objects: LaunchVehicle, Missile, Satellite

Type: Interval data given specified evaluation intervals and step sizes. Intended to be used only with elements from this same data provider.

Data Provider Elements

Name	Dimension	Type	Description
Impact mass fluence	MassPerArea	Real Number or Text	The total impact mass flux from all particulates (found as the integral of the particle impact flux distribution with respect to mass) integrated over the requested time interval. The integration is performed using Simpson's rule using a step size based upon the specified step size, adjusted to insure that an even number of steps is taken (as is required for Simpson's rule to be used).
Impact mass	Mass	Real Number or Text	The total mass impinging the spacecraft over the requested time interval. This is found by multiplying the cross sectional area by the impact mass fluence.
Impact fluence	Fluence	Real Number or Text	The total impact flux from all particulates (found as a simple sum of the impact flux of all particulates) integrated over the requested time interval. The integration is performed using Simpson's rule using a step size based upon the specified step size, adjusted to insure that an even number of steps is taken (as is required for Simpson's rule to be used).
Impacts	Unitless	Real Number or Text	The total number of impacts impinging the spacecraft over the requested time interval. This is found by multiplying the cross sectional area by the impact fluence.
