中国逐日格点降水数据集V2(1960–2024,0.1°)
CHM_PRE V2数据集是一套高精度的中国大陆逐日格点降水数据集。该数据集基于1960年至今共3476个观测站的长期日降水观测数据,并纳入11个降水相关变量,用于表征降水的相关性。数据集采用改进的反距离加权方法,并结合基于机器学习的LGBM算法构建。CHM_PRE V2与现有的格点降水数据集(包括CHM_PRE V1、GSMaP、IMERG、PERSIANN-CDR和GLDAS)表现出良好的时空一致性。数据集基于63,397个高密度自动雨量站2015–2019年的观测数据进行验证,发现该数据集显著提高了降水测量精度,降低了降水事件的高估,为水文建模和气候评估提供了可靠的基础。CHM_PRE V2 数据集提供分辨率为0.1°的逐日降水数据,覆盖整个中国大陆(18°N–54°N,72°E–136°E)。该数据集涵盖1960–2024年,并将每年持续更新。日值数据以NetCDF格式提供,为了方便用户,我们还提供NetCDF和GeoTIFF格式的年度和月度总降水数据。

Data From NSCLC-Radiomics
This collection contains images from 422 non-small cell lung cancer (NSCLC) patients. For these patients pretreatment CT scans, manual delineation by a radiation oncologist of the 3D volume of the gross tumor volume and clinical outcome data are available. This dataset refers to the Lung1 dataset of the study published in Nature Communications. In short, this publication applies a radiomic approach to computed tomography data of 1,019 patients with lung or head-and-neck cancer. Radiomics refers to the comprehensive quantification of tumour phenotypes by applying a large number of quantitative image features. In present analysis 440 features quantifying tumour image intensity, shape and texture, were extracted. We found that a large number of radiomic features have prognostic power in independent data sets, many of which were not identified as significant before. Radiogenomics analysis revealed that a prognostic radiomic signature, capturing intra-tumour heterogeneity, was associated with underlying gene-expression patterns. These data suggest that radiomics identifies a general prognostic phenotype existing in both lung and head-and-neck cancer. This may have a clinical impact as imaging is routinely used in clinical practice, providing an unprecedented opportunity to improve decision-support in cancer treatment at low cost. The dataset described here (Lung1) was used to build a prognostic radiomic signature. The Lung3 dataset used to investigate the association of radiomic imaging features with gene-expression profiles consisting of 89 NSCLC CT scans with outcome data can be found here: NSCLC-Radiomics-Genomics.
