Re: Help with concentration batch script
Good idea to use a script. Your script is running the trajectory code, hyts_std, but it should be running the dispersion/concentration code hycs_std. Also, it is better to avoid blank spaces in directory names, so try changing the directory name for the meteorology files.

Re: Trajectory Lat lon
With each step of the cluster process running in the GUI, you can look at your cluster working folder and see the file(s) that are created. Specifically you are looking for files named CN_Mmean.tdump, where N is the cluster number (what you are calling "a"), and M is the number of clusters.

Re: How Hysplit treats emission rate and emission duration hour?
These scenarios should give the same results. Look at the MESSAGE files from both the runs. Verify 1 minute time step for both scenarios - - DELT = 1.0 in the Namelist configuration list near the top of the file - in the lines where it has NOTICE: main 1 <time in minutes> <number of particles> <mass...

Re: Differences between results at different output resolutions and discrepancy between ascii values and corresp. contou
The contours in concplot are smoothed, so yes, there can be differences in the details you are looking at. Please plot using the hysplit utility program gridplot, which does not do contouring, it just plots the values on the grid. The program gridplot is in the PC distribution. In your figure wi...

Try to avoid roughly 07-10 UTC.

Re: Error in frequency analysis
This seems like it should be working. Try this: 1. Open the file ..\graphics/CLRTBL.CFG in Notepad. See if it looks alright - 4 columns of data. 2. Repeat the run in the command prompt, but use -k0 instead of -k1. That will be Black and White, but still using the CLRTBL. 3. In the command prompt, ru...

Re: Error while running hycm_std
You are getting that message, which also says "Simulation will continue on one processor!" because you are running with puffs (initd=2,3 or 4). If you can change to the particle mode initd=0 for 3-d particle, or initd=1 (Gaussian-horizontal vertical puff), then it will run as multi-processor. The in...

Re: Back trajectory temporal and spatial error
The exact spatial error as a function of time is not known. Running the ensemble option as you are doing gives you an estimate of the uncertainty - if all the trajectories are close together the error is relatively low, if they are far apart, the error is larger. The trajectories only track the me...
