<p class="MsoNormal">Dear all, <u></u><u></u></p>
<p class="MsoNormal">I’m processing the TES-Aura satellite data for HDO, but could not figure out the structure of the 4 sub-blocks of a 3D matrix, i.e., averagingkernel(grid-targets*<wbr>grid_pressure_composite*grid_<wbr>pressure_composite).

<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">As is stated in the guide, the averagingkernel consists of 4 sub-blocks of the matrix [0,0],[1,0],[0,1] and [1,1]. Subblock [0,0] ranges from indices ns to 16, and subblock[1,1] ranges from indices 17+ns to 33…<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Should it be something like this?<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">ak=F->AveragingKernel(vid,:,:) ; vid means valid observation meeting certain criteria<u></u><u></u></p>
<p class="MsoNormal">ak@_FillValue = -999<u></u><u></u></p>

<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">But the result of the corrected HDO using this averaging kernel does not seem right. Hope you would offer me more suggestions on this.<u></u><u></u></p>
