Starting in WRF-Hydro

[Gerardo Trossi]

Greetings,

I'm starting to work from zero on wrf-hydro, and I got a couple of questions:

1) First Step: Is it better to install from scratch WRF-Hydro or use the Docker version?

2) Ubuntu: If I was to use WRF-Hydro on my computer, can I use the Ubuntu version for Windows and not dual boot to Linux?

3) Forum: If I have more questions, should I use the same conversation or create a new one every time? 

I really appreciate any help you can provide.

Hi Gerardo Trossi, 

Welcome! 

1. I suggest looking at our FAQ webpage which will give you some guidance on getting started. For learning WRF-Hydro I suggest installing Docker and running through the online training lessons. 

2. I will let someone else comment on how you use WRF-Hydro on your computer. I do recommend you see the installation requirements to help you make the determination. 

3. If you have a question about a separate subject/topic, please start a new conversation/thread. 

Best regards,

Molly

Hi Gerardo,

I would suggest starting with the WRF-Hydro training container to familiarize yourself with the modeling system and a basic test case: https://hub.docker.com/r/wrfhydro/training (there's also a link from the materials Molly shared)

From there, where and how you'll want to run the model will depend on the computational requirements for your use case.  I would suggest starting by either running within a Docker container if you're familiar and would like to start there (we also have several others geared more toward testing and development on DockerHub) or a true linux system (e.g. Ubuntu).  While we have been able to get WRF-Hydro to run on WSL (e.g. Ubuntu for Windows), the I/O was so slow it wasn't even useful for demonstration purposes and there may have been some changes required to the source code.  For medium - large scale applications you'll likely need to run on a cluster or HPC system.  

Hope this helps!

Best,

Katelyn
