卫星探测辐射率在数值天气预报中的直接应用

DERECT USE OF SATELLITE SOUNDING RADIANCES IN NUMERICAL WEATHER PREDICTION

该文叙述在数值天气预报中直接应用辐射率而不经过反演的原因，变分法在辐射率直接应用中的作用，以及介绍变分问题计算中的伴随方法，还指出ＡＴＯＶＳ辐射率同样可以在ＮＷＰ中直接应用。最后，介绍业务ＮＷＰ直接应用辐射率的情况。

The paper described comprehensively that the satellite sounding radiances canbeused directly in NWP , not have to be retrieved by use of profiles of temperature andhumidity.The roles of variational algorithm for the direct use of radiances and thecalculation of the adjoint equation are presented.The direct method is very flexible andcan in principle be applied to ATOVS’ radiance inversion. And,the some aspects thedirect tise in operational NWPare also introduced.
