Meteorological data profiler - Control or Setup file

Post by villebm » March 28th, 2014, 3:49 am

Hi!
I am wondering if someone knows whether it is possible to manipulate and execute the meteorological data profiler in a similar manner to adjusting the Control and Setup.CFG before executing hyts_STD.exe. I have so far not been able to find the Control file for the Profiler.

What I wish to accomplish is to extract meteorological data from the gdas file that is not possible to output along the trajectory (in HYSPLIT Advanced/Configuration Setup/Trajectory/add meteorology along trajectory (6)). However since the trajectory is long, using the user interface would be too slow and I would write some script to rerun the Profiler for each lat/lon along my trajectory.

Does someone have previous experience with this or do you think that I should look for solutions outside HYSPLIT?

Thank you!

HYSPLIT can only output certain meteorological variables along a trajectory in the trajectory output file, tdump. Flags that indicate this are in the SETUP.CFG file. The code could be modified to be able to output other variables, but another way to get these variables is by using the program profile.exe, running once for each latitude and longitude endpoint. The 'profile' output is at the GUI / Meteorology / Display Data / Text Profile. Note 'profile' outputs values at the nearest meteorological grid point and at the meteorological levels.

Thank you for your answer Barbara. This is approximately how far I understood it, but unfortunately I am probably not able to manipulate the code to directly output the desired variables along the trajectory, hence, I will use the Profile.exe program.

Do you know if it is possible to manipulate the input to the Profile.exe (lat/lon and time) in a similar way to SETUP.CFG or control file? What I am looking for is a textfile that the profile.exe reads upon executing (the same input as in the user interface).

Thank you again,
Ville

profile.exe does not have an input file analogous to SETUP.CFG. Instead the inputs are entered on the command line. For example, say you want the profile at 40.0N, 90.0W, for every time period starting with the first time period of the file gdas1.apr14.w1, which is in c:\hysplit\working, run

C:\hysplit4\working>..\exec\profile.exe -d.\ -fgdas1.apr14.w1 -y40.0 -x-90.0 -t1

To see the command line options, run profile.exe without any command line options in the Command Prompt window, you will see the following "help":

Usage: profile [-options]
-d[Input metdata directory name with ending /]
-f[input metdata file name]
-y[Latitude]
-x[Longitude]
-o[Output time offset (hrs)]
-t[Output time interval (hrs)]
-n[Hours after start time to stop output (hrs))]
-w[Wind direction instead of components=1]
-p[process ID number for output text file]

NOTE: leave no space between option and value

Hi Barbara, I think your solution would work perfectly, however I am getting an error which I have troubles interpreting. Do you know what may cause this? My guess would be something with the coordinates, but I am out of luck here...

Here is my input and answer:

profile.exe -d[c:/hysplit4/working/] -f[gdas1.apr09.w1] -y[55] -x[13] -o[0] -t[3] -n[0] -w[0] -p[1]

I suggest starting with the minimum number of command line arguments to get a successful run, then tune it to exactly what you want. Minimum being -d -f -y -x.

Do not use the square brackets [ ]. Do not include "c:". For Windows, use the backslash \ instead of the forward slash /.
