简介:为了更好吸收,推进了初学者运作垂直更健全(ATOVS)发光数据并且为一个数字模型,提供更精确的起始的领域二个偏爱修正计划被采用改正ATOVS发光数据。在二个计划的差别在空气团偏爱修正躺在预言者使用。在计划1使用的预言者都从模型被获得第一猜测,当在计划2的那些来自第一猜测的模型和发光观察时。从二个计划的结果证明在偏爱修正以后,观察剩余变得对Gaussian分布更小、更靠近。为土地和海洋数据集合,从计划1获得的结果类似于从计划2的那些,它显示预言者能在ATOVS数据的偏爱修正被使用。

简介:在空气的顶的放射预算在气候研究起一个关键作用。比作宽带流动,幽灵似地解决的出去的longwave放射或流动(OLR),与在不同乐队的富有的大气的信息,在GCM的评估有明显的优点。不同于需要辅助大小和信息的方法,这里,我们拿大气红外线更健全(表情)观察作为一个例子当模特儿由尖分布造一个前後一致的算法(ADM),完全基于发光观察,在热带海洋上估计清楚天空的幽灵似地解决的流动。作为为如此的ADM的关键步骤,景色类型评价在选择表情隧道从发光和亮度温度被获得。然后,宽带OLR象一样合成光谱流动被导出由光谱ADM并且使用合成系列和谷神星验证(云和地球绚烂的精力系统)观察。处于大多数状况,之间的吝啬的OLR差别光谱ADM产品和CERES观察在钫?以内??醰顣鱎?????????
