[ncl-talk] How to process numerous files(data) in NCL

[时光足迹]

Hi there, 

    I have problems processing data with numerous files (~2GB each file) using NCL. 

    There are 10-year hourly 3-dimention meteological data in NetCDF format, which from 2010~2019, 2847 days in total. Data were stored daily (so there are 2847 files).  

    I want to caluclate some statistic varibles along all time in each grid. Take wsp(time|2847*24, level, lat, lon) for example, in the current method, do-loop on levels is used. Then 

'wsp' will be processed along time. Finally I can get what I need ( wsp_process(level,lat,lon) ）.
    However, it will be really ineffiency, and sometime it may meet error 'Segmentation fault (core dumped)'. 

    Is there any effiency way to meet my needs? 

Best regards,
HUANG
