  Brick Kilns are known to be a leading cause of air pollution. The toxins and
gaseous emissions from brick kilns leads to SMOG. It is a mixture of invisible
toxic gases such as carbon monoxide (CO), ozone (O$_3$), sulphur dioxide
(SO$_2$) and particulate matter like soot and carcinogens. We propose how low
spatial resolution remote sensing data can be used to identify illegal
industrial activity i.e. kiln operation particularly during winter SMOG period
through heat signature values and the concentration of gases like CO, NO$_2$,
SO$_2$ and O$_3$ in the atmosphere.
