interpol_pbl Subroutine

public subroutine interpol_pbl(itime, xt, yt, zt, zteta, ithread)

                                                                        *

This subroutine interpolates everything that is needed for calculating the* dispersion. * * Author: A. Stohl * * 16 December 1997 * * Revision March 2005 by AST : all output variables in common block cal- * culation of standard deviation done in this * routine rather than subroutine call in order * to save computation time * *

                                                                        *

Variables: * itime [s] current temporal position * memtime(3) [s] times of the wind fields in memory * xt,yt,zt coordinates position for which wind data shall be * culated * * Constants: * *
