EdgeCube measures the Red Edge that monitors a sharp change in the leaf reflection\u00a0in vegetation chlorophyll absorption and mesophyll scattering due to seasonal leaf stress.<\/p>\n

 <\/p>\n

 <\/p>\n

How’s it done?\u00a0EdgeCube monitors the red edge characteristics of 300 km areas of the earth using five narrow spectral bands in the wavelength range 630-800nm .<\/p>\n

 <\/p>\n

As an Earth-observing satellites, EdgeCube play a vital role in monitoring changes in the Earth\u2019s terrestrial ecosystems due to anthropogenic and natural drivers. Most optical satellite sensors, such as\u00a0NASA\u2019s Landsat and MODIS missions, have broadband measurements that bound the red edge\u00a0but do not directly measure it. Vegetation indices based on the contrast between red and NIR\u00a0reflectance, such as Normalized Difference Vegetation Index (NDVI) tend to saturate in\u00a0sensitivity at higher levels of vegetation structure (Wang et al., 2005). Brantley et al. (2011)\u00a0have shown that red edge measurements of high LAI canopies are accurate proxies to monitor\u00a0changes in these types of ecosystems without as much saturation.<\/p>\n

 <\/p>\n

EdgeCube will have the spectral detail in the red edge to calculate parameters such as REIP and magnitude at global scales with measurements as frequently as every 12 hours. By\u00a0surveying the Earth\u2019s surface frequently from space with EdgeCube, it may therefore be possible to provide information about ecosystem changes as they occur seasonally, in ways that\u00a0are not possible by directly measuring canopies from the ground or by conventional satellites.<\/p>\n
