ABoVE: MODIS- and CCAN-Derived NDVI and Trends, North Slope of Alaska, 2000-2015

This dataset provides the average Normalized Difference Vegetation Index (NDVI) at 1-km resolution over the north slope of Alaska, USA, for the growing season (June-August) of each year from 2000-2015, and NDVI trends for the same period. The dataset presents growing-season averages and trends from two sources: 1) derived from 1-km, 8-day data from the Moderate Resolution Imaging Spectroradiometer (MODIS) NDVI (MOD13A2) product, and 2) predicted by the Coupled Carbon and Nitrogen model (CCaN). CCaN is a mass balance carbon and nitrogen model that was driven by 1-km MODIS surface temperature and climate data for the North Slope of Alaska and parameterized using model-data fusion, where model predictions were ecologically constrained with historical ecological ground and satellite-based data.

本数据集提供了美国阿拉斯加北部斜坡地区在2000年至2015年生长季节（六月至八月）期间，平均标准化植被指数（NDVI）的1公里分辨率数据，以及同一时期的NDVI趋势。数据集展示了来自两个来源的生长季节平均值和趋势：1）由中等分辨率成像光谱辐射计（MODIS）NDVI（MOD13A2）产品的1公里、8日数据推导而来，2）由耦合碳氮模型（CCaN）预测。CCaN是一种质量平衡碳氮模型，其驱动数据来源于阿拉斯加北部斜坡地区的1公里MODIS地表温度和气候数据，并通过模型数据融合进行参数化，其中模型预测受到历史生态地面数据和基于卫星数据生态约束。
