Two Kinds of Cloud Top Height Retrieval Methods with Oxygen A-Band Comparison by Simulated Data and Verification with Experimental Results in China

Retrieval of cloud top height with oxygen A-band has been proposed for decades.However,with the development of space-based instrument,more attentions are being paid to this field again.Among various retrieval methods,SACURA and FRESCO+ are successful and mature.The ESA had already developed the cloud top height products retrieval by them.In order to evaluate the precision as well as applicability of these products and develop new generation oxygen A-band retrieval method in the future,sensitivity analysis is carried out herein.It is investigated that the result of FRESCO+ is insensitive to the surface albedo,cloud amount and other parameters.The cloud top height is underestimated about 20~750 m.While the result of SACURA is more susceptible to the solar zenith angle,cloud optical depth,surface property and cloud amount.The retrieval results of cloud top height change dramatically.Except the situation that the cloud optical depth is lower than 5,the average error of SACURA is smaller than 300 m with full cloud covering.Meanwhile,the result will be the worst if the value of cloud optical depth is smaller than 5 and the earth's surface is bright.The maximum error is more than 10 km.To confirm the conclusions above,verification with experimental results are also carried on.We firstly analyse statistically the satellite's cloud top height L2 products of 2008 which covers China and neighboring regions,and then compare with MACR and BBSS's information supplied by the ARM mobile facility located in Shouxian.The analysis shows that the conclusions,which are obtained by the simulations,are accurate and reliable.Besides,some suggestions for improvement of the algorithm and applicability of satellite products are also put forward.
