4.6 Million Citizens· Asia Metropolitan Baseline

Statistically typical versus the 30-day baseline. Air still exceeds the WHO health guideline — unusual and unsafe are different questions.

Gemini AI Synthesis & Plain-Language Summary

Gemini 3.5 Flash-Lite · Sensor & meteorological cross-match

In plain English: Surat is 0% above its 30-day Ozone (O₃) baseline (91 vs 56.7). Unusual does not automatically mean unsafe; this is a statistical departure from recent local weather, not an emergency siren.

Gemini may only interpret numbers already on this page. Chart annotations below are computed from the dated series (onset, peak, duration, latest vs baseline). Hypotheses are labeled and are not verified causes.

Surat is holding near its own 30-day baseline (no magnitude-gate or Isolation Forest flag). The satellite investigation engine stays idle so GIBS tiles are not fetched for unflagged cities. Unusual ≠ unsafe.
