<div>Dear Dennis,</div>
<div id="AppleMailSignature">Thank you for your reply. It is said that each <span style="background-color: rgba(255, 255, 255, 0);">observation has an averaging kernel matrix. The grid_pressure_composite includes 34 levels, with index 0 to 16 referring to hdo
and the remaining levels to h2o. Hdo and h2o vapor mixing ratio are retrieved simultaneously.</span></div>
<div id="AppleMailSignature">
<p class="MsoNormal" style="margin: 0in 0in 0.0001pt;"><span style="background-color: rgba(255, 255, 255, 0);">Each averaging kernel matrix has 4 sub-blocks correspond to the HDO/H2O ratio estimate , the H2o estimate and then the cross-terms.</span></p>
<p class="MsoNormal" style="margin: 0in 0in 0.0001pt;"><span style="background-color: rgba(255, 255, 255, 0);">The guide also explains that if the matrix is 32x32 then there are 4 components that are each 16x16 elements long. <o:p></o:p></span></p>
<p class="MsoNormal" style="margin: 0in 0in 0.0001pt;">Yet I still felt uncertain about the structure. Will this clarification help you in figuring out the structure of the sub block of the 3D matrix?</p>
