2 ngày trước · MODIS website informs a broad audience about MODIS data and products. The MODIS instrument is operating on both the Terra and Aqua spacecraft. It has a viewing swath width of 2,330 km and views the entire surface of the Earth every one to two days. Its detectors measure 36 spectral bands between 0.
4 thg 7, 2020 · MODIS 1B 数据位为 MODIS 影像数据的一级影像数据产品，有必要对其进行标准化再处理和产品生成，所以首要工作是做辐射定标、地理定位、数据的拼接、数据的裁切，然后进行投影变换等以及产品标准化、通用化方面的处理过程，为最后专题产品数据集 ...
3 ngày trước · MODIS is ideal for monitoring large-scale changes in the biosphere that are yielding new insights into the workings of the global carbon cycle. MODIS measures the photosynthetic activity of land and marine plants (phytoplankton) to yield better estimates of how much of the greenhouse gas is being absorbed and used in plant productivity.
MODIS传感器具有较高的分辨率，可以提供500米到1公里的空间分辨率。 这使得MCD43A4 V6数据集在对地表特征进行精细刻画时具有优势，并可以用于监测地表变化和研究区域尺度的空间差异。
