Description

From the listing uploaded by “appupdater”.

Haze is traditionally an atmospheric phenomenon where dust, smoke and other dry particles obscure the clarity of the sky. Though not a common occurrence in Singapore, it does still happen from time to time especially during the Southwest Monsoon season from June to September. Haze is traditionally an atmospheric phenomenon where dust, smoke and other dry particles obscure the clarity of the sky. Though not a common occurrence in Singapore, it does still happen from time to time especially during the Southwest Monsoon season from June to September. Haze@SG is useful utility that allows you to check the hourly Pollutant Standards Index (PSI) on the go. PSI is a measurement developed by the United States Environmental Protection Agency (USEPA) which provides an accurate, timely and easily understandable indicator of daily levels of air pollution. The 1-hour PM2.5 concentrations reflect the PM2.5 levels averaged over one hour, and can give you an indication of the current air quality. However, the 1-hour PM2.5 concentration levels can be volatile and tend to fluctuate over the day especially during periods of transboundary haze. Short-term fluctuations will also be very heavily influenced by weather conditions. Features include: - Access to hourly AQI Reading for better assessment of the air quality - Access to hourly PM2.5 Reading - Access to hourly PSI (24-hours, PM2.5 Concentration based) across Singapore from NEA on the go. - Understand what the current PSI means to you - Notification when PSI reaches unhealthy level. Notification can be turned on and off as per your preference. - Share the current AQI/PSI/PM2.5 with your friends and family and keep them informed and safe! Note: This app is developed without any involvement of NEA. Any inaccuracies found are not the responsibility of and should not be attributed to NEA. Note: We are working very hard to make the app as reliable as possible before the haze season. Please always try to update to the latest version for the best user experience.
