青藏高原Landsat系列卫星遥感增强植被指数（EVI）产品（1980s-2019）

1）数据内容：本数据集包含从1980s-2019年青藏高原地区Landsat长时序EVI。2）数据来源及加工方法：主要是在青藏高原Landsat系列卫星地表反射率数据集的基础上，通过EVI的计算公式进行生产的，即并在NDVI计算公式的基础上引入了背景调节参数C1，C2和大气修正参数L进行计算的。3）数据质量描述：为了标识云、冰雪，并相应生产了质量标识文件（QA）。4) 数据应用成果及前景：EVI相比于NDVI具有较强的抗大气干扰能力以及抗噪音能力，更适用于气溶胶含量较高的天气状况下，以及植被茂盛区。

1) Data Content: This dataset contains long-time-series Enhanced Vegetation Index (EVI) data for the Qinghai-Tibet Plateau from the 1980s to 2019.
2) Data Source and Processing Method: This dataset is primarily generated using the EVI calculation formula, which is based on the Landsat satellite surface reflectance dataset of the Qinghai-Tibet Plateau. The EVI formula introduces background adjustment parameters C1, C2 and atmospheric correction parameter L on the basis of the Normalized Difference Vegetation Index (NDVI) calculation formula.
3) Data Quality Description: To identify clouds and snow/ice, corresponding quality assessment (QA) files have been generated.
4) Data Application Value and Prospects: Compared with NDVI, EVI has stronger resistance to atmospheric interference and noise, and is more suitable for weather conditions with high aerosol content and dense vegetated areas.
