Plain English answer (default view) — what you'd actually write on the test

🔬 Technical version / model bullets (revealed on click) — one bullet per line TM thermal was 120 m; ETM+ improved to 60 m; TIRS is 100 m.

💡 Mnemonic / memory aid (shown on hover) Thermal got BETTER over time: TM 120 → ETM+ 60 → TIRS 100 (resampled to 30). Don't confuse 30 m (VSWIR bands) with the much coarser thermal.
