Running WRF in AWS Cloud ("No matching AMIs found")

[hermawanwiwid]

Hi WRF Community,

I'm trying to follow the AWS tutorial here:Cloud WRF

Step 4 mentions these AMIs:
- CloudWRF_AMI: ami-0815f1678f4949559
- wrfv4_wpsv4_gnu: ami-0041e40831eedc4f2

But in AWS Console (us-east-1, Public Images), I get "No matching AMIs found" for both.

Questions:
1. Are these AMIs deprecated/removed?
2. What are the current/replacement AMI IDs?
3. Is there an updated tutorial or alternative setup?

Thanks for any help!
