Re: api2arl_v4: unable to convert precipitation rate

OK I can confirm that, by setting PRT3 as you suggested, I am able to read the PRATE data from the grb file.
I take the opportunity to ask another question: where do I find the complete list of parameters and instructions on how to set the values of sfccat, sfcnum and sfccnv correctly?

Thanks
Fabio

Re: api2arl_v4: unable to convert precipitation rate

Hi, OK thank you for the clarification. Yes it's over 1 hour. Actually if you look at the grib file, there are two "PRATE" fields: one is the "instantaneous" precipitation rate (valid at the time step) and the other is the average. This is a bit more complicated. For the attached case, the averaged ...

api2arl_v4: unable to convert precipitation rate

Hi, I am converting GFS 0.25deg grib files into arl format. It works almost perfectly, with the exception of the 1-hour precipitation. This causes hysplit to fail when wet removal is activated. I attach the api2arl.cfg file I am using and the original grib file. Is there anything wrong in the api2ar...

Re: Parallel version slower than the serial one

Hi, OK I have increased the release time to 6 hours (so three times longer) and in fact the parallel version is much faster than the serial one, but only if I use one pollutant . With multiple pollutants the serial version is still significantly faster even with a longer emission time. And for my ro...

Re: Parallel version slower than the serial one

Hi,

with 1 pollutant the serial case took 1.412 secs while the parallel one (with 10 cores) took 1.564 secs.

Thanks

Parallel version slower than the serial one

Hi, I am facing this issue with the parallel version. I have compiled it with mpich by amending the Makefile.inc file, and it successfully generated the parallel executable (hycm_std). I am now running a test case both with the serial code (as usual) and parallel. The serial code took less than 8 se...

Deposition plots

Hi, I have a question about deposition plots. With concplot it is possible to obtain deposition plots, I can do that and it's fine. However, I was now exploring the possibility to convert HYSPLIT outputs into NetCDF first in order to use my own plotting scripts. When I run con2cdf4, I noticed that t...

Emission file: has the format changed?

Hi, I am now using the latest version of HYSPLIT and it looks like the emission file I used to use is not working anymore. I attach it for reference (with an added extension for enabling the upload). HYSPLIT seems to run file, but concplot fails to display anything since it detects only zeroes. It i...

Re: Problems with era52arl

Hi, I have an update. I have first downloaded the latest version of the pre-compiled UNIX distribution. In the meantime I have also asked for the most recent source code. I have managed to compile era52arl and run again the scripts. Same error messages, unfortunately. I have managed to make it work ...
