Data Corruption: 3 UTIG transects incorrectly interpolate longitude when crossing +/- 180 deg

lauralindzey commented 1 year ago

For now, these are explicitly excluded in the UTIG index step (it's not sustainable to add a special case that detects this and corrects it).

If they're fixed, we'll include them again.

I sent an email to Scott, and he's looking into it:

In 3 granules, the flight path crosses between +/- 180 degrees longitude. And it looks like y'all interpolated positions across ~4 traces, and did it in such a way that values go the long way around through zero. I've attached a plot for one of these.

This happened in:

IR2HI1B_2011031_ICP3_JKB2d_F56T01e_002.nc
IR2HI1B_2013015_ICP5_JKB2h_RIGGS1a_003.nc
IR2HI1B_2013025_ICP5_JKB2h_RIGGS1b_006.nc

Screencap, matching the format in #4

(these are no longer excluded; I've written code to filter them out so we can see the otherwise-OK radar data)
