netcdf文件外推工具
ncgrow的Python项目详细描述
ncgrow
以增大/扩展遮罩字段，使其延伸到遮罩中。主要用于在重新划分后或用于可视化的情况下使用陆海掩模扩展海洋数据。脚本迭代计算权重和索引，然后应用它们
安装
ncgrow可以在下载此存储库后通过运行：
python3 setup.py install [--user]
通过运行：
pip3 install ncgrow
开发
包装
创建分发：
python3 setup.py sdist bdist_wheel
之后，可以将包上载到pypi。
用法
ncgrow脚本有以下用法。
usage: ncgrow [-h] [-v [..]] [-d [..]] [-m [..]] [--maskfile filename]
[--smooth [..]] [--fill [..]] [-i [..]] [--niter_chunks [..]]
[-c [..]] [-O] [-V] [--version]
infile outfile
Grow/extend and/or fill masked fields.
positional arguments:
infile path to source file.
outfile filename of the output file.
optional arguments:
-h, --help show this help message and exit
-v [..], --variables [..]
list of variables to extend, e.g. -v temp,elev.
-d [..], --dims [..] Dimension subset, e.g. -d level,1,10,2
-m [..], --maskvar [..]
Variable name for land-sea mask that will be the
enforced.
--maskfile filename External file containing mask variable(s), i.e.
maskvar. Will be used before infile in case maskvar is
present in both.
--smooth [..] Smooth grown cells to avoid unphysical values. Can
also be specified per variable, e.g. --smooth
True,temp, --smooth False,ice. default is True.
--fill [..] Default value to apply to any cells that are not
missing_value or Fillvalue in maskvar. Will be ignored
if --maskvar is not set. Optionally one can select
'max' 'min', 'mean' of variable or None. Can also be
specified per variable, e.g. --fill mean, temp, --fill
0,ice.
-i [..], --iterations [..]
Number of iterations to use, corresponds to one land
cell per iteration. optionally with variable name
appended, e.g. -i 2,temp,elev. Multiple defintions
possible for granulated control.
--niter_chunks [..] Maximum number of iterations to hold in memory. Will
reduce performance, but enable larger dataset and
number of iterations. Optionally with variable name
appended. Multiple defintions possible for granulated
control. Default is 5.
-c [..], --converge [..]
Converge towards a given value 'V' with a factor f =
[0-1] (default = 1). If not set no convergence is
applied. e.g. -c 0,0.25,ice. Multiple defintions
possible for granulated control.
-O, --overwrite Overwrite output file if it exist (or append to input
file).
-V, --verbose Increase runtime information.
--version show program's version number and exit
