中文摘要：

中国阳光 Hazemeter 网络(CSHNET ) 提供基于 necessaryground 的观察验证并且估计 MODIS 喷雾器的适用性在在中国的不同生态、地理的区域上的光深度(AOD ) 产品第一次。Thevalidation 结果证明 MODIS 产品的全面利用比率和适用性从 2004 年 8 月在不同区域和季节上非常变化了到 2005 年 7 月。在 TibetanPlateau 上， MODIS 数据的全面利用比率是低的：MODIS 产品仅仅说明了 16% 基于地面的观察；平均， 31% ～ 45% MODIS 产品在 NASA 发出的检索错误以内掉落了。类似的结果与 MODIS 的比率在北荒芜的区域被发现到观察从 15% ～ 55%，与在错误以内的 7% ～ 39% MODIS 产品。中国的 Inthe 遥远的东北角落，到观察的 MODIS 的低比率也被发现从 14% ～ 46%，与在错误以内的 49% ～ 69% MODIS 一起。Theforested 地点展出了 MODIS 的中等比率到观察从 46% ～ 65%，与在错误以内的 30% ～ 59% MODIS 一起。这类似于沿着中国和内陆的东方海岸在地点观察的数字有在63%～75%之间的 MODISto 观察的比率的城市的地点与在为沿着中国的东方海岸的地点的错误以内的25%～67% MODIS 和43%～78%一起，与在为内陆的错误以内的35%～75% MODIS 一起城市的地点。到在农业区域上的观察的 MODIS 的比率从 61% ～ 89%； 59%—88% MODIS 在检索错误以内倒下了。在同类、好的生长区域， MODIS 产品的全面利用比率是超过 80% ，在 70% MODIS 上面，产品在检索错误以内倒塌了种季节。

英文摘要：

The Chinese Sun Hazemeter Network （CSHNET） provides the necessary ground-based observation to validate and assess the applicability of MODIS aerosol optical depth （AOD） products over different ecological and geographic regions in China for the first time. The validation results show that the comprehensive utilization ratio and applicability of MODIS products varied very much over different regions and seasons from August 2004 to July 2005. On the Tibetan Plateau, the comprehensive utilization ratio of MODIS data was low： MODIS products only accounted for 16% of the ground-based observation; on average, 31% to 45% of MODIS products fell within the retrieval errors issued by NASA. A similar result was found in northern desert areas with the ratio of MODIS to observation ranging from 15% to 55%, with 7% to 39% of MODIS products within errors. In the remote northeast corner of China, low ratios of MODIS to observation were also found ranging from 14% to 46%, with 49% to 69% of MODIS within errors. The forested sites exhibited moderate ratios of MODIS to observation ranging from 46% to 65%, with 30% to 59% of MODIS within errors. This was similar to numbers observed at sites along eastern seashore of China and inland urban sites with the ratio of MODIS to observation between 63% to 75%, with 25% to 67% of MODIS within errors for sites along eastern seashore of China and 43% to 78%, with 35% to 75% of MODIS within errors for inland urban sites. The ratio of MODIS to observation over agricultural areas ranged from 61% to 89%; 59%-88% of MODIS fell within the retrieval errors. At homogeneous and well vegetated areas, the comprehensive utilization ratio of MODIS products was over 80% and above 70% of MODIS products fell within the retrieval errors in growing season.
