Study On Above Ground Biomass Products From Gcom-C / Sgli

Japan Aerospace Exploration Agency (JAXA) had launched new Earth observation satellite GCOM-C in the end of 2017. The core sensor of GCOM-C, Second Generation Global Imager (SGLI) has a set of along track slant viewing Visible and Near Infrared Radiometer (VNR). These multi-angular views aim to detect the structural information from vegetation canopy, especially forest canopy, for estimating productivity of the vegetation. SGLI Land science team has been developing the algorithm for Above Ground Biomass, Vegetation Index, Shadow Index, etc.We developed the ground observation method using Unmanned Aerial Vehicle (UAV) in order to contribute the algorithm development and its validation. Mainly, multiangular spectral observation method and simple BRF model have been developed for estimating slant view response of forest canopy. The BRF model developed by using multiangular measurement has been able to obtain structural information from canopy. In addition, we have conducted some observation campaigns on typical forest in Japan in collaboration with other science team experienced with vegetation phenology and carbon flux measurement. Primary results of these observations are also be demonstrated.
