链接失效反馈资源简介：
The following folders contain data obtained from two-dimensional Particle Image Velocimetry (2D-PIV) experiments for each region where measurements were conducted. Due to the domain size and experimental constraints, the domain containing the barchan dune interacting with a turbulent water flow was divided into three sections (parts). Along the folders, these portions of the domain are referred to as part_1, part_2, and part_3. Cross-correlated PIV data, in vc.7 format, obtained from the commercial software DaVis, are made available. However, due to size restrictions of this data repository, only 10% of the total of 2,000 temporal velocity fields are included. Post-processed data, saved as Matlab matrices, are also made available, corresponding to the total of the 2,000 temporal velocity fields. Additionally, Matlab codes are provided to generate the matrices from the data on DaVis and to plot pertinent results. Note that this folder contains only data from experiments on single dunes. In each subfolder is provided an explanation of its contenent.

PartNet
我们介绍了PartNet: 一个一致的、大规模的三维对象数据集，用细粒度的、实例级的和分层的三维零件信息进行注释。我们的数据集包括573,585个零件实例，超过26,671个3D模型，涵盖24个对象类别。该数据集支持并充当许多任务的催化剂，例如形状分析，动态3D场景建模和仿真，可承受分析等。使用我们的数据集，我们建立了用于评估3D零件识别的三个基准任务: 细粒度语义分割，分层语义分割和实例分割。我们对四种最先进的3D深度学习算法进行了基准测试，用于细粒度语义分割，并对三种基线方法进行了基准测试。我们还提出了一种新颖的零件实例分割方法，并证明了其优于现有方法的性能。

中国区域250米植被覆盖度数据集（2000-2024）
该数据集是中国区域2000至2024年月度植被覆盖度产品，空间分辨率250米，合成方式采用月最大值合成，每年12期，共299期。本产品采用基于归一化植被指数（NDVI）像元二分模型，根据土地利用类型确定纯植被像元值和纯裸土像元值，实现植被覆盖度计算。本产品去除湖泊、河流、冰川/永久积雪等区域。其中，NDVI数据来源于国家青藏高原科学数据中心中国区域250米归一化植被指数数据集（2000-2024）产品。通过时空变化趋势分析检验法分析，该数据集符合时间变化趋势和空间变化趋势。该数据集能够为全国区域生态质量评价、重要生态空间调查评估等工作提供数据参考。

Paper III (Walker et al. 2024)
Data products used in 3-D CMZ Paper III, Walker et al. (2024). The full cloud catalogue is provided in tabular format, along with a full CMZ map showing the clouds and their assigned IDs. For each cloud ID in the published catalogue there are: - Individual cube cutouts from the MOPRA 3mm CMZ survey (HC3N, HCN, and HNCO). - Individual cube cutouts from the APEX 1mm CMZ survey (13CO, C18O, and H2CO). - Cloud-averaged spectra of the ATCA H2CO 4.83 GHz line. - PV slices of the ATCA H2CO 4.83 GHz line, taken across the major axis of the source. - Where applicable, there are mask files which correspond to the different velocity components of the cloud. In these cases, there are two mask files per velocity component, corresponding to the different masking approaches described in the paper.
