<div dir="ltr"><div>Hi Huang,<br></div><div>This question is a bit vague, at least I am not what statistics you are trying to calculate. NCL can do array processing for certain things, however, for a better answer to your specific needs, you would need to be specific about what exactly you are trying to do? <br></div><div><br></div><div>Rashed<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, May 21, 2020 at 6:56 PM 时光足迹 via ncl-talk <<a href="mailto:ncl-talk@ucar.edu">ncl-talk@ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div>Hi there, <br></div><div> I have problems processing data with numerous files (~2GB each file) using NCL. <br></div><div> There are 10-year hourly 3-dimention meteological data in NetCDF format, which from 2010~2019, 2847 days in total.
