Convert the ECMWF model level products to pressure level products
@scottstanie @mirzaees @vbrancat
To make the pyAPS accept the ECMWF model level products, this PR is to convert the model level ECMWF products in NetCDF format to the pressure level products. Both the theory and partial codes for the conversion can be found in ECMWF website. This PR is tested comparing with the ECMWF pressure level products. Some tests results are shown as,
1. Temperature
2. Specific Humidity
3. Geopotential
@scottstanie @mirzaaes can you please review this PR? We would like to have a quick turn around on this and I believe this PR should be also beneficial for your projects. Thank you.
I am a little concerned about how to deal with those NaNs that are out range of the pressure, interestingly, the downloaded pressure level products do not have this issue.
I am thinking two options, Option 1: Interpolating them, in this way, we might introduce more delays. Option 2: Skip the NaNs when calculate the delay, in which we might need more code change of the pyAPS to deal with NaNs.
Since there is already GRIB test data in the repo, it should be quick to add a test of the main conversion function
