Mpasjedi: how to generate 4d simulated observations

I could be using mpasjedi_hofx3d.x and hofx3d.yaml to generate simulated observations in 3D. But how to generate four-dimensional simulated observations using background field files of multiple time? I didn’t find an executable file like mpasjedi_hofx4d.x. Or can mpasjedi_hofx3d.x also do simulated observations in four dimensions?

Hi @LL_GZ,

We don’t yet actively support 4D H(x).

I didn’t find an executable file like mpasjedi_hofx4d.x. Or can mpasjedi_hofx3d.x also do simulated observations in four dimensions?

There does exist an executable for 4D H(x) under build/bin directory: mpasjedi_hofx.x

As shown in the corresponding ctest yaml file (test/testinput/hofx.yaml), this includes the model integration inside the application (see yaml key model). You might want to compare test/testinput/hofx.yaml and test/testinput/hofx3d.yaml to see the major differences on the configuration.

But how to generate four-dimensional simulated observations using background field files of multiple time?

Currently, mpasjedi_hofx.x can not handle the background field files of multiple time. As noted above, the application directly includes the model integration and simulates the 4D H(x).

Thank you,
BJ
