气象卫星专题气候产品数据集-归一化植被指数（NDVI）（1988-2020）

FY-1A/B/C/D MVISR及FY-3A/B/C再处理NDVI月产品数据集是利用风云卫星再定标处理后的L1数据，采用统一算法反演合成NDVI产品。风云一号卫星MVISR再处理月NDVI数据集包括FY-1A/B/C/D现有资料全周期的NDVI月产品，空间分辨率为0.05°×0.05°。其中A,B星为中国区，C，D星包含全球数据，风云三号卫星VIRR再处理月平NDVI数据集包括FY3A/B/C星全周期全球月合成NDVI数据，空间分辨率为0.05°×0.05°。相比于业务数据，该数据集在精度和稳定性两方面均明显提升。

The reprocessed monthly NDVI product dataset of FY-1A/B/C/D MVISR and FY-3A/B/C is developed using recalibrated Fengyun satellite L1 data, with NDVI products retrieved and synthesized via a unified algorithm. The reprocessed monthly NDVI dataset of FY-1 MVISR covers full-cycle monthly NDVI products derived from all available FY-1A/B/C/D data, with a spatial resolution of 0.05°×0.05°: FY-1A and FY-1B only cover the Chinese region, while FY-1C and FY-1D include global coverage data. The reprocessed monthly averaged NDVI dataset of FY-3 VIRR contains full-cycle global monthly composite NDVI data from FY-3A/B/C, with a spatial resolution of 0.05°×0.05°. Compared with operational datasets, this product has markedly improved accuracy and stability.
