pardump not reading READY HYSPLIT PARDUMP.#### files

[klarsonSITC]

Hello, I'm attempting to use MONETIO to read the PARDUMP file generated by running HYSPLIT on the READY server. The "self.pardt" formatting in the MONETIO "pardump.open_dataset" function doesn't seem to be the same as the generated PARDUMP.#### (#### = job number) file. Here is what I'm doing:

Input: (minus path) `import monetio as mio import glob

folderpath = "path" partfiles=glob.glob(folderpath+"/PARDUMP") part = mio.pardump.open_dataset(partfiles[0],century=2000,verbose=1)`

Output: `Record Header [(28, 10020, 1, 22, 12, 24, 23, 0)] Date 2022-12-24 23:00:00 **** None Adding data [(28, 10020, 1, 22, 12, 24, 23, 0)] 2022-12-24 23:00:00 Record Header [(7, 0, 1, 1, 8907, 20, 4, 940279797)] Traceback (most recent call last):

File "C:\Users\klarson\Anaconda3\lib\site-packages\monetio\models\pardump.py", line 36, in open_dataset pardf = pdump.read(drange=drange, century=century, verbose=verbose)

ValueError: month must be in 1..12`

Using the Debugger, I looked at the par_frame before the padding is dropped. There seems to be an offset as the pandas array fills "lon", "ht", and "su" with the latitude, longitude, and height values (see attached screen shot). I'm not sure if this is a general issue with all PARDUMP HYSPLIT files or if this is solely a PARDUMP generated-on-the-READY-server HYSPLIT file issue. I have the same dispersion back trajectory from READY file I was attempting to read attached as a zip file below.

Hi @klarsonSITC , thanks for this report. I know @amcz made some changes to HYSPLIT reading that we haven't released yet, but I don't think the pardump reader was touched.

I cannot reproduce your error using the PARDUMP.21498 file you provided. See screenshot. Can you provide more information on your system?

[klarsonSITC]

Sorry for the delay, I have a windows system. Thank you for the help!

@klarsonSITC this should now be fixed in our develop branch. And I will try to do a new conda-forge release soon.

@klarsonSITC Has this been resolved?
