She added that the 24-hour PSI forecast is useful for planning activities the next day, while the 1-hour PM2.5 reading gives a better picture of current air quality. #singapore #sgnews #haze Subscribe to our channel here: https://cna.asia/youtubesub Visit our website: https://cna.asia Download our app: https://cna.asia/app Get our editors' picks of stories via chat apps: Telegram: https://cna.asia/telegram WhatsApp: https://cna.asia/whatsapp Follow us on these platforms: https://www.facebook.com/channelnewsasia https://www.instagram.com/channelnewsasia https://www.tiktok.com/@channelnewsasia
