I would like to output a timeseries of tracer concentration at a single point, i.e. for state variable ‘tr17_1’ I would like to have a timeseries output from any single grid point in the domain.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>It appears that using ‘tslist’ one can only output a limited number of surface and diagnostic type variables. Can you suggest another way to accomplish this? One way might be to modify ‘solve_em.F’ such that after each timestep data from tracer(Nx,Nz,Ny,2) is written to a file, however, this approach is probably not very computationally efficient.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Regards,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Anders<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-bottom:solid windowtext 1.5pt;padding:0in 0in 1.0pt 0in'><p class=MsoNormal style='border:none;padding:0in'><o:p> </o:p></p></div><p class=MsoNormal>Anders Nottrott<o:p></o:p></p><p class=MsoNormal><i>PhD Student, Mechanical and Environmental Engineering<o:p></o:p></i></p><p class=MsoNormal>University of California, San Diego<o:p></o:p></p><p class=MsoNormal>Department of Mechanical and Aerospace Engineering<o:p></o:p></p><p class=MsoNormal>Website: <solar.ucsd.edu/nottrott><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
