Comparisons And Validation Of The Simulated Carbon Dioxide Fluxes With The HIAPER Pole-to-Pole Observations

In this article, we present description, validation and utilization of the National Institute for Environmental Studies Transport Model (NIES TM) off-line global atmospheric tracer transport mode. We compared the NIES TM simulated fluxes with data from the HIAPER Pole-to-Pole Observations (HIPPO) Data, including HIPPO-1,2,3,4,5 to validate the precision of this model as well as the distribution of the sources and sinks about carbon dioxide. The model transport is driven by analyzed meteorological fields JCDAS/JRA-25 and consisted of a terrestrial biosphere exchange fluxes, fossil fuel, air-ocean exchange, biomass burning and inverse correction fluxes of carbon dioxide (CO2) by GOSAT Level 4 product, the model is designed to simulate the CO2 vertical profiles of HIPPO-1,2,3,4,5 from 2009 to 2011.By Compared the simulation results with HIPPO CO2 observations, we focus on the precision of the model for simulation of the Green House Gas CO2. The results suggested that, the model can produce realistic distributions in troposphere and in lower stratosphere, and the simulation results is good to simulate CO2 flux with the low bias about ±2ppmv.
