Dear WRF forum members,
I am the upper atmosphere researcher, who wants to use WRF model for the MLT layer.
I am creating an initial data from ERA-5 pressure level data and JAWARA re-analysis data, which covers up to ~140 km.

I made a test initial data as following steps:
1. Run WPS to create metgrid data from ERA-5.
2. My python script marge the metgrid with JAWARA reanalysis data. JAWARA data was just interpolate into an input resolution with scipy.interpolate.RegularGridInterpolator and was just added above 1 hPa (above top of ERA-5 pressure data).
3. The metgrid data was input to real.exe.
However, the output data is very different from the original JAWARA data, while below 1 hPa, they are same as the ERA-5 data.
I have two questions:
1. I believe that metrgid process just interpolate. Is this correct?
2. How does real.exe create initial data from metgrid? I wonder if the error is caused by inputing inconsistent data.
Welcome to any suggestions.
Thank you in advance,
Masaru
