Assimilation of MODIS AOD in WRFDA

[cce_space]

Hello,

I was following the tutorial (Chapter 6: WRFDA) on how to use WRFDA until I reached the part of the available data to be used in WRFDA. Unfortunately, MODIS seems to be not on the list, and I am planning to use MODIS AOD to forecast air quality in WRF-Chem. I have read that it is possible to create your own input data for WRFDA, but I do not know where to start. Given, for example, a MODIS AOD NetCDF4 file.

Would it be possible to assimilate MODIS AOD in WRFDA? Also, would it also be possible to assimilate other available data, for example ground sensor measurements?

I have been trying to do the assimilation with Gridpoint Statistical Interpolation (GSI) to no avail; I have been following its tutorial (Case 9: Chem case: GSI analysis for WRF-Chem | dtcenter.org), yet I always reach a segmentation fault, and it seems that GSI is no longer supported.

I'm actually trying to do the exact same thing, for both GSI and WRFDA.


After all this time, have you found any solution or made any progress on this?
If you have any tips, updates, or materials you could share, it would be really helpful!


Thanks!
