HYSPLIT back trajectories for potential source contribution function studies of trans boundary pollution episodes (pscfV6).

Abstract

A program that calculates the parameters needed to generate a Potential Source Contribution Function (called PSCF) has been implemented. When using PSCF the user specifies two values through the use of the standard deviation of the dataset to subdivide the data into 3 sets. Following this, the parameters that are required for the generation of a Potential Source Contribution Function are estimated by the program for each of the three regions. The program and its input and output files are described in this report. It can generate either forward or backward trajectories through the specification of the length of the trajectory to consider, forward is specified by a positive length and backward is specified by a negative length.
