Electronic WBGT meter Analog WBGT meter consisting of three thermometers and a slide rule to compute WBGT. The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans.
Aside of this structure, BMKG maintained 181 meteorological, climatological, and geophysical stations which its operations and management performed by 5 regional Indonesian Institutes for Meteorology, Climatology, and Geophysics (Indonesian: Balai Besar Meteorologi, Klimatologi, dan Geofisika, abbreviated BBMKG) responsible.
An air quality index (AQI) is an indicator developed by government agencies [1] to communicate to the public how polluted the air currently is or how polluted it is forecast to become.
The air quality in Malaysia is reported as the API (Air Pollutant Index) or in Malay as IPU (Indeks Pencemaran Udara). Four of the index's pollutant components (i.e., carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide) are reported in ppmv but PM 2.5 particulate matter is reported in μg/m 3.
The heat index was developed in 1979 by Robert G. Steadman. [1] [2] Like the wind chill index, the heat index contains assumptions about the human body mass and height, clothing, amount of physical activity, individual heat tolerance, sunlight and ultraviolet radiation exposure, and the wind speed.
For health reasons it is crucial to breathe clean air, free from chemicals and toxicants as much as possible. It is estimated that humans spend approximately 90% of their lifetime indoors [8] and that indoor air pollution in some places can be much worse than that of the ambient air.
