Processing ERA5 data in LVT

[slinskik]

Hi LIS team - I am encountering errors when I try to process ERA5 precipitation and surface air temperature data in LVT. The error I get is:

Error************
observation init routine for source ERA5 is not defined
please see the configs/lvt.config.master file.....
program will seg fault.....
Error************

Any advice would be greatly appreciated. I have attached my config file. Many thanks for your help!

Hi @slinskik,

I went back and looked at pull request #646 that added this feature and I noticed the same thing during my review. In that thread @sujayvkumar indicated that this is expected behavior so he may be able to explain what's going on.

@bmcandr - many thanks for the pull request information!

I was able to process ERA5 data after taking the following steps:

1. downloaded and compiled the latest LVT executable from the master branch
2. added the following constraint to my slurm file: #SBATCH --constraint="sky|cas" (ERA5 processing in LVT crashes when run on a compute node and on Haswell nodes - this pertains only to running on Discover)

Also, I needed to correct the datastream attributes in my lvt.config file. They are:
TotalPrecip 1 1 kg/m2 DN 3 1
Tair_f 1 1 K - 1 1

Many thanks to @emkemp for his help troubleshooting this and finding a solution.
