Also, this ensemble dimension is not well defined according to the CDM standard. I created a ncml for your reference, but this ncml file only modified the the single grib file, you can not do the aggregation with it. Loading this ncml file to the IDV, the display is a bit normal than the original file, and you can actually load the second ncml file.
