In a stable atmosphere, the change in pressure (in kilo Pascal) at a height of $100 \mathrm{~m}$ from the mean sea level is $\_\_\_\_$. (rounded off to three decimal places)
[Density of air is $1.029 \mathrm{~kg} \mathrm{~m}^{-3}$ and acceleration due to gravity is $9.81 \mathrm{~m} \mathrm{~s}^{-2}$]
