沙尘暴过程观测数据与实测数据的综合分析

不断加深沙尘暴起沙、传输、沉降机制及其辐射强迫机理认识,提高沙尘暴的预测预警以及防治水平,已成为科研界和政府部门共同关注的问题.我们充分利用已观测的数据进行了深入的综合研究和方法探索,在数据处理本身和多元数据分析方面均取得一些新进展.本文充分利用遥感观测和地面实测手段,对亚洲沙尘暴进行监测.通过对多元数据进行分析和综合,建立了遥感监测结果与地面观测结果之间的关联关系,这些监测结果能够为综合风侵蚀模型系统和GCM(全球尺度沙尘模拟模型)模型系统提供参数和验证数据,同时为沙尘暴的预警预报提供基础数据和客观依据.

Synthetical analyses of the observational data and measured data from dust storms

Considerable efforts have been made during the past several years by either the scientific community or governments in Asian countries to study the dust mechanisms in terms of emission, transporting and deposition and to improve forecasting sandstorms. We have made best use of the data collected during the testing phase and found that some new progress has been made in parameter retrieval, data fusion and comprehensive use. In this paper, we use remote sensing observation and surface measurement methods to adequately monitor Asian duststorms and synthetically analyze the monitored results, which can provide abundant parameters and validated data to GCM dust model and, at the same time, provide foundation data for forecasting duststorms.
