Difference between SAFAR and AQI and NAAQS

Difference between SAFAR and AQI and NAAQS is mention below in table.

SAFARNAAQSAQI
System Of Air Quality and Weather Forcasting and ResearchNational Ambient Air Quality Standards (NAAQS)Air Quality Index (AQI)
Introduced by the Ministry of Earth Sciences.Notified by Central Pollution Control Board (CPCB)Initiated by the Ministry of Environment Forest and Climate Change under Swachh Bharat Abhiyan.
Developed indigenously by the Indian Institute of Tropical Meteorology (IITM), Pune, and operationalized by India Meteorological Department (IMD).Under The Air (Prevention and Control of Pollution) Act, 1981.It is a colour coded index graded with possible health impact.
Provide location-specific information on air quality in
near real-time and its forecast 1-3
days in advance
. For greater metropolitan cities of India
 There are six AQI categories, namely Good, Satisfactory, Moderately polluted, Poor, Very Poor, and Severe.
Pollutants monitored: PM1, PM2.5, PM10, Ozone, CO, NOx (NO, NO2), SO2, BC, Methane (CH4), Non- methane, hydrocarbons (NMHC), VOC’s, Benzene, Mercury.Covers 12 pollutants: Sulphur Dioxide, Nitrogen Dioxide, PM-10, PM-2.5, Ozone, Lead, Carbon Monoxide, Ammonia, Benzene, BenzoPyrene, Arsenic, Nickel.Measure 8 major pollutants – Particulate matter (PM 10 and PM 2.5), Nitrogen dioxide, sulphur dioxide, ozone, carbon monoxide, ammonia and lead.
Also monitor the existence of Benzene, Toluene and Xylene.  
Monitored Meteorological Parameters: UV Radiation, Rainfall, Temperature, Humidity, Wind speed, Wind direction, and solar radiation.
