Ph. Wang et al., RETRIEVAL ANALYSIS OF AEROSOL-SIZE DISTRIBUTION WITH SIMULATED EXTINCTION MEASUREMENTS AT SAGE-III WAVELENGTHS, Applied optics, 35(3), 1996, pp. 433-440
The retrieval of aerosol-size distribution from simulated aerosol-exti
nction-coefficient measurements of the new satellite instrument, the S
tratospheric Aerosol and Gas Experiment (SAGE) III, is investigated. A
detailed discussion on the aerosol-size-distribution information cont
ent of the SAGE III aerosol-extinction-coefficient measurement is prov
ided. Results of the investigation indicate that unimodal as well as b
imodal log-normal size distributions can be inferred. In addition, it
is shown that a shape-constraint-free size distribution can be derived
from SAGE III aerosol measurements by use of the randomized minimizat
ion search technique and the optimal estimation theory.
