Re: meteorology data stored in several files

Hi Alice, Thank you for your help. I consider re-downloading everything as my last option because I am planning to run a 38-year trajectory, which requires an enormous amount of data, re-downloading may be too time-consuming. I will study the code more to see if I can get a better way on this proble...

Re: meteorology data stored in several files

Hi Alice, I noticed that the problem is in the subroutine ANALYZE in both grib2arl and ecm2arl. Even though the maximum input files in the ecm2arl is four, but it still misses the second 3D file. Perhaps I should modify this subroutine? Could you give me some advice on this? Many thanks! Best, Yang

Re: meteorology data stored in several files

Hi Alice, I have tried the ecm2arl command as you suggested, however, it still doesn't work. The situation is the same with grib2arl: It stopped and I got the message of "WARNING: moisture fields missing (SPHU or RELH)" and "ERROR: height field required with pressure levels","stop 1131", as I looked...

Re: meteorology data stored in several files

Hi Alice,

Thank you for your suggestions. I am working on the compilation of ecm2arl.
But meanwhile, could you please tell me how to modify the grib2arl program so that it can read multiple files?

Many thanks!

Best,
Yang

Re: meteorology data stored in several files

Hi Alicec, Thank you for your help! There is a version problem with the gfortran in my server, so I couldn't run the executables in the hysplit package. The admin then installed the grib2arl in the server so I tried that one to see how it goes. Two issues appeared: 1. It seems that the grib2arl can'...

meteorology data stored in several files

Hi, I am trying to convert the ERA-interim data into arl format. However, the variables are not stored in the same file. For example, I have one file of u, v, w; and another file of T, q and z. The surface file includes 10m u and v, 2m T and dewpoint T as well as other variables like mean sea level ...

Re: Can't open grib_api.mod

Dear Fantine, Thank you so so much for your help. I modified the code but it still failed. The message shows as follows: gfortran -I/opt/gribapi/include -I/opt/jasper -I/opt/gribapi/include -g -O2 -fconvert=big-endian -frecord-marker=4 -ffree-form -c -o api2arl_v4.o api2arl_v4.f gfortran -I/opt/grib...

Re: Can't open grib_api.mod

Dear Fantine, Thank you so much for your reply. Could you please tell me more about it? The variable FCLINK is related to libtool, which is used in api2arl_v4. Relative lines in the makefile are: LIBTOOL = $(SHELL) $(top_builddir)/libtool FCLINK = $(LIBTOOL) --tag=FC \ --mode=link $(FCLD) $(AM_FCFLA...
