@haydenlj this adds a couple new IODA definitions... one key one is that for IPP and forgot to ask @davidkuhl

it's maybe Ionospheric Pierce Point ?

Thanks @BenjaminRuston I was able to run

Ok I'll add these to the IODA definitions PR. Thanks!

@BenjaminRuston I checked the testoutput/obs.20201001T000000Z_PT1M_tec_groundbased.nc4, which only has one group, MetaData. There is no ObsValue group. Is it correct?

[BenjaminRuston]

@huishao-r this is fixed and can now make a plot of the data... notice the units for this TEC for the groundbased is in different units then the TEC from the space-based GNSS receivers.... they use something called TECU not sure what units these groundbased TEC are in

The test_iodaconv_tec_groundbased test passed, but the IODA validator prints some errors in the IODA conventions:
