Abstract

The performance of a space-borne incoherent Doppler lidar system has been discussed by using modeled atmosphere and analytical calculations. With using the modeled atmosphere, the analytical calculations, and reasonable instrumental parameters, we estimated the error on the line-of-sight (LOS) wind under the assumptions that the horizontal and temporal variation of tropospheric aerosol and atmospheric molecule is negligible in no cloud condition. We used the solar radiance value measured in the troposphere to discuss the LOS wind error on the effect of the solar radiance during daytime. Although the LOS wind error depends on the system parameters, the comparison between the various analytical calculations suggested that the LOS wind errors for those the analytical methods were almost the same values. The simulations showed that the LOS wind error during daytime was almost the same as that during nighttime, suggesting that the wind velocity can be made measurement under the same LOS wind error condition if the integrated solar bandwidth of the filter is narrow enough.
