xarray: N-D labeled arrays and datasets in Python

xarray：python中的多維層次陣列與資料集

xarray (formerly xray

) is an open source project and Python package that aims to bring the labeled data power of pandas to the physical sciences,by providing N-dimensional variants of the core pandas data structures.

xarray（之前的xray）是一個開源的python程式包，其目的是通過提供以pandas為核心的多維資料結構變體，將pandas層次化的優點應用於物理科學中。

Our goal is to provide a pandas-like and pandas-compatible toolkit for analytics on multi-dimensional arrays, rather than the tabular data for which pandas excels. Our approach adopts the

Common Data Model for self-describing scientific data in widespread use in the Earth sciences:xarray.Dataset is an in-memory representation of a netCDF file.

我們的目標是建立一個類似pandas並可相容pandas的工具，用於分析多維array陣列，而不是pandas擅長的表格資料。我們的方法吸收了一個用於實現科學資料自我描述的基礎資料模型（common data model），它廣泛應用於地球科學的資料處理中：xarray.Dataset

在記憶體中代表一個netCDF格式的檔案。

History歷史

xarray is an evolution of an internal tool developed at The Climate Corporation. It was originally written by Climate Corp researchers StephanHoyer, Alex Kleeman and Eugene Brevdo and was released as open source inMay 2014. The project was renamed from “xray” in January 2016.
