Simulation of Aeolus CM wind observations and recommendations for Aeolus sampling

GJ Marseille

The Lidar Performance Analysis Simulation (LIPAS) simulates Aeolus winds and wind errors
and has been used for several ESA Aeolus scientific studies in the past. Since the start of
the development in 1999, LIPAS has undergone several upgrades to stay in line with the
most recent Aeolus design characteristics. An extensive validation of LIPAS with the Aeolus
E2S-L1Bp-L2Bp simulator-processor chain was performed showing compatibility of resulting
simulated winds and wind errors.

Potential Aeolus continuous mode sampling scenarios are simulated based on an atmospheric database composed of CALIPSO background and co-located ECMWF dynamics and temperature. Simulations of Aeolus winds in realistic atmospheric scenes show that about 85-100 km along track integration of raw data is needed to obtain winds fulfilling the mission requirement of about 2 m/s wind error standard deviation.
