AORC Subset

The objective of this HydroShare resource is to query AORC v1.0 Forcing data stored on HydroShare's Thredds server and create a subset of this dataset for a designated watershed and timeframe. The user is prompted to define their temporal and spatial frames of interest, which specifies the start and end dates for the data subset. Additionally, the user is prompted to define a spatial frame of interest, which could be a bounding box or a shapefile, to subset the data spatially.

Before the subsetting is performed, data is queried, and geospatial metadata is added to ensure that the data is correctly aligned with its corresponding location on the Earth's surface. To achieve this, two separate notebooks were created - [this notebook](https://github.com/CUAHSI/notebook-examples/blob/main/thredds/query-aorc-thredds.ipynb) and [this notebook] (https://github.com/CUAHSI/notebook-examples/blob/main/thredds/aorc-adding-spatial-metadata.ipynb) - which explain how to query the dataset and add geospatial metadata to AORC v1.0 data in detail, respectively. In this notebook, we call functions from the AORC.py script to perform these preprocessing steps, resulting in a cleaner notebook that focuses solely on the subsetting process.

本HydroShare资源旨在查询存储于HydroShare Thredds服务器上的AORC v1.0强迫数据，并为指定流域和时间段创建该数据集的子集。用户被要求定义其感兴趣的时间空间框架，从而确定数据子集的起始和结束日期。此外，用户还需定义一个感兴趣的空间框架，该框架可以是边界框或Shapefile，以对数据进行空间子集化。在执行子集化操作之前，将查询数据并添加地理空间元数据，以确保数据与地球表面相应位置的正确对应。为此，创建了两个独立的笔记本——[本笔记本](https://github.com/CUAHSI/notebook-examples/blob/main/thredds/query-aorc-thredds.ipynb)和[该笔记本](https://github.com/CUAHSI/notebook-examples/blob/main/thredds/aorc-adding-spatial-metadata.ipynb)——分别详细解释了如何查询数据集以及如何向AORC v1.0数据添加地理空间元数据。在本笔记本中，我们调用AORC.py脚本中的函数以执行这些预处理步骤，从而使得笔记本更加简洁，专注于子集化过程。
