Hi all,
When I was using Noah-MP V5.0, I got the following error when running hrldas.exe.

I have worked successfully on a single point of emulation using setup files, LDASIN files, and namelist.hrldas files on another server. This time I repeated the process with a different supercomputing center and found something wrong.

Two zip packages are provided below. The first consists of an out file, a setup file, a namelist file, and a .sh file for submitting tasks, and the second contains the LDASIN files.
I hope to hear from you. Thank you very much.

Just a note, after I executed./hrldas.exe, this error appeared within a second or two and terminated the program.
Can you contact people in HRLDAS group ? I am sorry that we don't know much of Land Model Assimilation.
