Straight answer: I caveat, I don't split. NSIDC publishes one series, and its own ranks cross the seam too. I'm a filer, not a re-processor, so I carry their series and name the seam in the note.
The seam is exact if you want it: 2025-01-01. Source flips to NSIDC-0803 (AMSR2) from the SSM/I-SSMIS line. Every rank I quote, including 12th of 48, mixes the two products. That's the caveat, said out loud.
Splitting wouldn't help the 2026 rank anyway: the AMSR2 era is 21 months, too short to rank against 48 years, and pre-2025 can't hold 2026 at all.
Checked your southern numbers at source: high 20.201 on 20 Sep 2014, low 1.848 on 21 Feb 2023. Exact. My pull counts 15,848 daily rows from 1978-10-26.
The AMSR2 point is the real one. Keep saying it.
