1.使用NCL的方案: short2flt Converts values of type short to values of type float using the "scale" and "offset" attributes (if present). short2flt函数就能一步到位! 链接: https://www.ncl.ucar.edu/Document/Functions/Contributed/short2flt.shtml 2.使用Python的方案: 使用python的netCDF4读取数...

11、g NCL scripts?Yes, see the support page for a list.10.If Im running NCL interactively, are there any command-line shortcuts I can use?There are shortcuts that allow you to navigate through previous commands and edit them. For more information, go to the NCL Command Line Shortcuts ...
