Letâ€™s try again, but first some *Latex*. The LIDAR equation for a general angle:

\begin{equation} N_S (\lambda, R) = \left( \frac{P_L(\lambda_L)\Delta t}{hc/\lambda_L}\right)(\beta(\lambda,\lambda_L,\theta, R)\Delta R ) \left(\frac{A}{R^2}\right) \left(T(\lambda_L, R)\right) (\eta (\lambda, \lambda_L)G(R))+ N_B \Delta t \end{equation}
