Hi,<br> I have a 4D data (lon=144,lat=90,lev=24,time=100), with many missing values that are randomly located. I want to have an averaged output at every level i.e. , output file should have lon=1,lat=1,lev=24,time=1 At any level, I want to give equal weightage to all the data during the entire time period. So area averaging at first (aave) and then avergae over time is not appropriate. Is there a way to do this in GrADS?<br>
<br>thanks in advance.<br><br><br><br clear="all"><br>-- <br>John Guhin<br>
