1. Related factors (forecast of weather conditions impacting PM 2.5 based on meteorological conditions).
From 2 to 3 Feb 2026, air ventilation is expected to be "weak/good" with the near-surface atmosphere alternating between open and closed conditions and receiving southern winds from the Gulf of Thailand. This will reduce dust accumulation. Today is expected to be cool with some morning fog, and temperatures will slightly decrease.
2. Satellite hotspot data checked by NASA show no abnormal heat spots over Bangkok that would indicate fires or unusual heat sources contributing to pollution.
3. Public advisories encourage residents to check air quality information before leaving home via:
- LINE ALERT service.
