Generation of Decadal Global High Resolution L-band Sar Dataset for Forest Carbon Tracking

Recently, the forest observation using the spaceborne sensor becomes a top issue in the carbon monitoring. Covering more than 20% of the global terrestrial areas, forests are rapidly decreasing, corresponding to 20% carbon dioxide release from the land. Deforestation and forest degradation mainly occurred in the developing country. L-band SAR is sensitive for monitoring the forest biomass, forest-non-forest classifications because of its sensitivity. JAXA has been observing the global land surface since 2006 by ALOS/PALSAR and from 1992 to 1998 by JERS-1/SAR. Making all the data archives and converted to 10m high-resolution global mosaic data sets for these years can be fully utilized for detection of the forest carbon changes. JAXA recently decided to create these high-resolution global mosaic datasets and generate the forest/non-forest classification. In this paper, we will introduce the current status of generation of the mosaic and high-level data sets. Keyword: PALSAR, Orthorectified mosaic, Kyoto and Carbon initiative
