Correlation of MODIS Products with Ground Based Measurements: A Review

Abstract

Air pollution is a global issue that continues to affect human health, environmental nature and
other living organisms alike in developed and developing countries by introducing diverse pollutants into the
atmosphere. Anthropogenic activities and natural events produce harmful green house that leads to
deterioration of air quality. The occurrence of Particulate Matter (PM) often called “aerosols” causes more
threat to human well-being and influences uncertainty in “Earth's radiation budget”. According to WHO
(2018), nearly 4.1 million lose their life Worldwide from lung cancer, respiratory infection, heart disease,
and stroke due to exposure to PM2.5. This may be due to rapid industrialization, urbanization, and improper
abatement guidelines. Developed countries has a handful of resources which can monitor status of air quality
by using broad monitoring stations from urban to rural. Whereas, developing countries due to resource
constraints spread of geographical extent of networks is limited to urban areas. In those circumstances,
better-validated air quality models (AQMs) helps in better understanding on air quality status. Remote
sensing satellite observations give status of air quality in Spatio-temporal pattern of columns. Since last two
decades there is an enormous advance in satellite technology. This article mainly focused on correlations of
satellite products (MODIS) with ground-based observations and MODIS applications in various
circumstances.
