SAFARI 2000 MISR Level 2 Data, Southern Africa, Dry Season 2000

MISR (Multi-angle Imaging SpectroRadiometer) views the sunlit Earth simultaneously at nine widely spaced and collects global images with high spatial detail in four colors at every angle. These images are carefully calibrated to provide accurate measures of the brightness, contrast, and color of reflected sunlight. The change in reflection at different view angles affords the means to distinguish different types of atmospheric particles (aerosols), cloud forms, and land surface covers. Combined with stereoscopic techniques, this enables construction of 3-dimensional models and more accurate estimates of the total amount of sunlight reflected by Earth's diverse environments.MISR was built for NASA by the Jet Propulsion Laboratory. It is part of NASA's Terra spacecraft, launched into a polar orbit around the Earth on December 18, 1999.The Southern African Fire Atmosphere Research Initiative (SAFARI) 2000 field campaign focused on the smoke and gases released into the environment of southern Africa by industrial, biological, and man-made sources such as biomass burning. The area of study and MISR path numbers include Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Zambia, and Zimbabwe. These MISR data cover the period August 12 through September 28, 2000.

MISR（多角度成像光谱辐射计）能够同时对阳光照耀下的地球进行九个广泛分散角度的观测，并收集全球图像，在每个角度上以四种颜色提供高空间细节的全景图像。这些图像经过精心校准，以确保对反射阳光的亮度、对比度和色彩进行精确测量。不同视角下反射的变化为区分不同类型的气溶胶、云型和地表覆盖提供了手段。结合立体摄影技术，这有助于构建三维模型，并对地球多样环境中反射的总阳光量进行更精确的估算。MISR由NASA委托喷气推进实验室建造，是NASA的Terra航天器的一部分，于1999年12月18日被发射至地球极地轨道。南非火灾大气研究倡议（SAFARI 2000）野外考察活动专注于由工业、生物和人为来源（如生物质燃烧）释放到南非环境中的烟雾和气体。研究区域和MISR路径编号包括博茨瓦纳、莱索托、马拉维、莫桑比克、纳米比亚、南非、斯威士兰、赞比亚和津巴布韦。这些MISR数据涵盖了2000年8月12日至9月28日的时间段。
