National Certification - ISO 9001:2008 Accredited International Recognition - World Meteorological Organization (GURME - Pilot)
SHORT RANGE FORECAST: (1) Delhi: Overall AQI today indicates ‘moderate’ air quality. Fine particles (size < 2.5 micrometer) contribute ~ 35% to PM10 indicating dominance of coarse or dust particles. For the next 3 days, surface wind speed (14 to 16 km/h) and temperature (Max 30-32 deg C; Min 17-19 deg C) are likely to slightly worsen air quality. Mixing layer height is likely to be ~ 3 km that causes moderate ventilation of pollutants. Moderate surface winds are likely to maintain dispersion and air quality. Over all air quality is likely to be within ‘moderate’ for the next 3 days due to dispersion by surface wind speed. (2) Mumbai, Pune and Ahmedabad: AQI of Pune indicates ‘satisfactory’ air quality today and likely to be within ‘satisfactory’ for next two days. AQI of Mumbai indicates ‘satisfactory’ and likely to be within ‘satisfactory’ for next 2 days. AQI of Ahmedabad today indicates ‘lower end of moderate’ air quality and likely to be within ‘moderate’ for next two days.
