This program serves as a pivotal element in India&#8217;s inaugural Air Quality Early Warning System, currently active in Delhi. SAFAR monitors various environmental parameters, including temperature, rainfall, humidity, wind speed and direction, UV radiation, and solar radiation, among others. Recognizing the high-quality control and standards upheld in its execution, the World Meteorological Organization has acknowledged SAFAR as a prototype activity.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_73 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<label for=\"ez-toc-cssicon-toggle-item-69d2f3fb625fa\" class=\"ez-toc-cssicon-toggle-label\"><p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-cssicon\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-69d2f3fb625fa\"  \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/edukemy.com\/blog\/safar-system-for-monitoring-air-pollutants-upsc-environment-notes\/#DEVELOPED_BY\" title=\"DEVELOPED BY\">DEVELOPED BY<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/edukemy.com\/blog\/safar-system-for-monitoring-air-pollutants-upsc-environment-notes\/#HOW_IS_AIR_QUALITY_INDEX_CALCULATED_IN_INDIA\" title=\"HOW IS AIR QUALITY INDEX CALCULATED IN INDIA\">HOW IS AIR QUALITY INDEX CALCULATED IN INDIA<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/edukemy.com\/blog\/safar-system-for-monitoring-air-pollutants-upsc-environment-notes\/#OBJECTIVES\" title=\"OBJECTIVES\">OBJECTIVES<\/a><ul class='ez-toc-list-level-4' ><li class='ez-toc-heading-level-4'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/edukemy.com\/blog\/safar-system-for-monitoring-air-pollutants-upsc-environment-notes\/#The_primary_objectives_are\" title=\"The primary objectives are:\">The primary objectives are:<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/edukemy.com\/blog\/safar-system-for-monitoring-air-pollutants-upsc-environment-notes\/#SIGNIFICANCE\" title=\"SIGNIFICANCE\">SIGNIFICANCE<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/edukemy.com\/blog\/safar-system-for-monitoring-air-pollutants-upsc-environment-notes\/#FAQs_SAFAR_%E2%80%93_SYSTEMS_FOR_MONITORING_AIR_POLLUTANTS\" title=\"FAQs: SAFAR &#8211; SYSTEMS FOR MONITORING AIR POLLUTANTS\">FAQs: SAFAR &#8211; SYSTEMS FOR MONITORING AIR POLLUTANTS<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/edukemy.com\/blog\/safar-system-for-monitoring-air-pollutants-upsc-environment-notes\/#1_What_is_SAFAR_and_what_is_its_primary_purpose\" title=\"1.

Featuring a large true-color LED (Light Emitting Diode) display, the system provides a continuous, real-time Air Quality Index (AQI) with color-coded information, accessible 24 hours a day, 7 days a week. Additionally, the system offers a 72-hour advance forecast.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"HOW_IS_AIR_QUALITY_INDEX_CALCULATED_IN_INDIA\"><\/span>HOW IS AIR QUALITY INDEX CALCULATED IN INDIA<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The calculation of the Air Quality Index (AQI) in India is based on the average concentration of a specific pollutant measured over a standard time interval. For most pollutants, the time interval is 24 hours, but for carbon monoxide and ozone, it is 8 hours.<\/p>\n\n\n\n<p>Eight individual pollutants are monitored for the calculation of AQI in India. These pollutants include PM10 (Particulate Matter with a diameter less than 10 micrometers), PM2.5 (Particulate Matter with a diameter less than 2.5 micrometers), nitrogen dioxide, sulphur dioxide, carbon monoxide, ground-level ozone, ammonia, and lead.<\/p>\n\n\n\n<p>To calculate the AQI, data for a minimum of three pollutants must be present, and one of these must be either PM10 or PM2.5. The AQI provides a standardized way to communicate the level of air quality to the public, incorporating multiple pollutants to offer a comprehensive assessment of air pollution.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"OBJECTIVES\"><\/span>OBJECTIVES<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_primary_objectives_are\"><\/span>The primary objectives are:<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Raising Public Awareness: The aim is to inform and educate the public about the air quality in their city. By enhancing awareness, the goal is to encourage individuals to take necessary precautions and support appropriate mitigation measures. The ultimate objective is to empower the community to actively contribute to improving air quality.<\/p>\n\n\n\n<p>Assisting Policymakers: The system is designed to provide valuable data and insights to policymakers. This information aids in the development of effective mitigation strategies while considering the economic prosperity of the country. By offering a comprehensive understanding of air quality trends, policymakers can make informed decisions to address environmental concerns without compromising economic development.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"SIGNIFICANCE\"><\/span>SIGNIFICANCE<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Implementing the system will result in cost savings across various industries, including agriculture, aviation, infrastructure, disaster management, tourism, and others. These sectors, whether directly or indirectly influenced by air quality and weather conditions, stand to benefit from the accurate and timely information provided by the system. The efficiency gained in decision-making and planning within these industries can lead to substantial economic advantages and improved resource utilization.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"FAQs_SAFAR_%E2%80%93_SYSTEMS_FOR_MONITORING_AIR_POLLUTANTS\"><\/span>FAQs: SAFAR &#8211; SYSTEMS FOR MONITORING AIR POLLUTANTS<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_What_is_SAFAR_and_what_is_its_primary_purpose\"><\/span>1.
