Development of a rapid global aircraft emissions estimation tool with uncertainty quantification
Aircraft emissions impact the environment by changing the radiative balance of the atmosphere and impact human health by adversely affecting air quality. Many tools used to quantify aircraft emissions are not open source and in most cases are computationally expensive. This limits their usefulness …
