Development and application of GCOM-C LAI and GPP/NPP research products

GCOM-C SGLI land products are being developed toward better understandings of terrestrial carbon cycle and future climate change projection. In this paper, we will introduce two research products, Leaf Area Index (LAI) and Net Primary Productivity (NPP) and their application of these products to earth system models (ESMs). The LAI product as research product is an improved version from standard product. The LAI retrieval is based on FLiES canopy radiative transfer model with improved treatment to boreal to arctic ecosystems by including overstory and understory vegetation. NPP and GPP products are based on improved version of BESS (Breathing Earth System Simulator) model, and initial results are discussed. Using these potential products, our goal is to evaluate and improve ESMs. We will show initial comparison of satellite-based products of LAI, GPP, NPP with ESM outputs, and evaluate similarity and differences between satellite products and model outputs.
