The total irradiance on a Lambertian surface is 540 \(W\,m^{-2}\). The reflectance of the surface is 20%. The path radiance from the atmosphere towards the sensor is 2.5 \(W\,m^{-2}\,sr^{-1}\). The transmissivity of the atmosphere is 80%. The radiance reaching the sensor is ________ \(W\,m^{-2}\,sr^{-1}\) (Rounded off to the nearest integer).
