Hi,
I am running DDM with CMAQv5.3.3. I’ve already run it successfully when I set 2 or 3 sensitivities. However, I got this error when I defined 44 first-order and second-order sensitivities with specific regions.
I tried to limit the species output for DDM and changed the AVG_CONC_SPCS in run_cctm.csh. But this did not change the output species in the CTM_SWETDEP_1. Could someone help me to solve this problem? Thank you for taking the time.
Here’s my sensinput.dat and log file. sensinput_CN3GD.dat.txt (3.6 KB) CTM_LOG_000.PRD_process_2_d03_mcip5.0_base_20210920.txt (1.9 MB)
For CMAQ-DDM, ioapi-3.2-large has expanded maximum-number-of-files and maximum-variables-per-file parameter-values. This version should be kept carefully isolated from the regular version of the I/O API, and should be used only for CMAQ-DDM and CMAQ-ISAM
Additionally, once you install the I/O API-large library and rebuild your executables, you can verify that the correct library is being used by paying attention to this portion at the beginning of the CTM_LOG file you posted:
ioapi-3.2: $Id: init3.F90 185 2020-08-28 16:49:45Z coats $
Version with PARMS3.EXT/PARAMETER::MXVARS3= 2048
netCDF version 4.6.2 of Oct 7 2019 01:45:40 $
As @cjcoats noted, with the I/O API-large library the message should then show that MXVARS is 16384 which should get you past the error you’re currently encountering.
Dear Carlie,
Thanks for your kind reply. I have downloaded ioapi-3.2-large.tar.gz. I found no Makefile file under $BASEDIR. I tried to copy Makefile.template from ioapi-3.2. The air2m3 error occured when compiling m3tools.
The loaded modules are as follows:
It is recommended that you disable these options by adding the command-line flags below to your netCDF configure command:
--disable-netcdf4 --disable-dap
or (depending upon netCDF version; don’t you love consistency and compatibility !?? )
--disable-netcdf-4 --disable-dap
If you build netCDF-4 without the --disable-netcdf4, you will also need to add -DIOAPI_NCF4=1 either to the ARCHFLAGS in your Makeinclude.${BIN} or to the DEFINEFLAGS in your Makefile, since defining netCDF-4 causes netCDF to change parts of the netCDF-3 interface.
Thanks for your suggestion. I would like to try running DDM. At the moment it seems that the issue is not the version, but the IOAPI version. I will consider upgrade CMAQ later.
Dear Carlie,
Sorry for the delay in the response. I have tried to recompile netcdf4 with command: ./configure --prefix=/BIGDATA1/app/netcdf/4.6.2-icc-18/disable-netcdf4 CPPFLAGS=-I/BIGDATA1/app/hdf5/1.8.21-icc-18/include LDFLAGS=-L/BIGDATA1/app/hdf5/1.8.21-icc-18/lib CC=icc --disable-dap --disable-dap-remote-tests --disable-netcdf4
I have compiled ioapi and m3tools separately. And I got same error when I compiled m3tools before and after recompiling netcdf. Here are log file and makefiles.
