Running OBSGRID for Non-Surface and Minute-Level Data: Guidance Needed

Hello,

I want to run OBSGRID for non-surface data, but I’m unsure how to create the OBS:????-??-??_?? format required as input for OBSGRID.
Has anyone run OBSGRID for vertical data before? If so, do you have any guidelines on how to generate the OBS:????-??-??_?? file?
Additionally, does anyone have experience running OBSGRID with minute-level observations?

Thank you

Hi, Naser, Can you help me guide for me way to setup OBSGRID step by step from repository: GitHub - wrf-model/OBSGRID: Repository for OBSGRID
I'm facing error when compile. Error attacked below file.

Hi,

Unfortunately, in my case, someone else compiled the code, so I only ran OBSGRID myself.
If you are unable to compile it successfully, I recommend creating the Little_R file directly by following the guideline below:

I’m really sorry I couldn’t be of more help.
Good luck!
 
Thanks for sharing your experiences—this thread has been helpful as I’m also working on getting OBSGRID running, particularly for fine-scale and non-surface observational data.


I’ve been experimenting with preprocessing tools to convert various observation formats (including minute-level data) into Little_R. It’s definitely tricky when dealing with non-standard intervals or vertical profile data. One approach that worked for me was customizing a Python script to format raw input into the required OBS:YYYY-MM-DD_HH naming structure. If you're looking to automate or simplify part of that, I’ve documented some of the steps and shared a few tools I used on my site.


Also, for anyone dealing with stubborn compile issues, I’d recommend checking your compiler version and NetCDF dependencies—it can be surprisingly version-sensitive. More on that in one of our posts here: Download Null’s Brawl APK Latest _v59.197_For_Android_IOS


Hope this helps someone else facing the same hurdles!
