Manu Mehta and Akhilesh Kumar Estimating atmospheric aerosol levels is crucial for accurate radiative forcing calculations, understanding aerosol effects on cloud formation, assessing human health impacts, and planning pollution control. Continuous monitoring of aerosols in both space and time is essential to understand its effects in human life. Ground-based networks like AERONET and ARFINET use instruments such as sun-photometers and Continue Reading »
