## Context There are different pollutant gases in air. Carbon Monoxide (CO) is one of them. It is often called "Silent Killer" as being colour-less, odour-less and poisonous. Data about different pollutant gases is well documented by EPA in US is available publicly. This dataset is extracted from daily summary data for CO gas from year 2000-2018. It was done for an extension of a academic project. ## Content This dataset presents daily reading of Carbon Monoxide (CO). It has columns describing point where reading were taken (Address, State, County) and readings (Arithmetic Mean, 1st Max Value, 1st Max Hour, AQI). ## Acknowledgements Data in this dataset comes from EPA database : https://aqs.epa.gov/aqsweb/airdata/download_files.html ## Inspiration Analysing CO level from day to day reading.
At what time of day CO levels are high?
How CO varies from state to state?
How CO level vary in different seasons?
What factors affect CO level? What model can be used to predict future possible CO level on selected address?
