Bad longitude interpolation in UTIG's GIMBLE + COLDEX radargrams #15

Open lauralindzey opened 2 months ago

Affected transects are:

ICP5/JKB2h/RIGGS1a, granule 003
ICP5/JKB2h/RIGGS1b, granule 006
ICP6/MKB2l/F09T01a, granule 004

I plotted data directly from the netcdf (downloaded from Texas Data Repository) to double-check that I wasn't introducing errors. Here's the plot for F09T01a, clearly showing bad interpolation for longitude.

Ugh. It looks like COLDEX_2024 also has the same problem for several flights:

F04T01a, granule 007
F10T01a, granules 000, 001
PPT/MKB2o/Y01d, granules 000, 001
TAM/MKB2o/SHKTG01a, granules 000, 001

As did COLDEX_2023 for a whole nest of them:

I've pinged the UTIG folks; while I could write code that filters out these bad points and replaces them with interpolation handled correctly, I'm hoping for a fix from their end.
