CAAoMOD_ValidationDataset

The accuracy of the standard MODIS daily snow cover products and several of the most common and computationally frugal gap filling methods were validated using 12 years of daily snow observations from over 800 SNOTEL stations. This is the joined csv of those station observations with the various MODIS snow cover datasets tested extracted from Google Earth Engine, and may be used to verify or further explore the accuracies of the MxD10A1 (c5) datasets.

Used in the "Comprehensive Accuracy Assessment of MODIS Daily Snow Cover Products and Gap Filling Methods" paper published in ISPRS Journal of Photogrammetry and Remote Sensing.

采用超过800个SNOTEL气象站12年以来的每日积雪观测数据，对标准MODIS每日积雪覆盖产品及几种常见且计算效率较高的数据填充方法进行了验证。此csv文件为这些气象站观测数据与从Google Earth Engine提取的多种MODIS积雪覆盖数据集的合并，可用于验证或进一步探究MxD10A1（c5）数据集的准确性。该成果已发表在《ISPRS摄影测量与遥感杂志》的“MODIS每日积雪覆盖产品及数据填充方法综合准确性评估”一文中。
