GOSAT-2 EORC Daily Partial Column GHGs


Last update: 2020/05/22

1. Introduction

TANSO-FTS-2 simultaneously observes both reflected shortwave-infrared (SWIR) solar light and thermal infrared (TIR) emissions with a single FTS-mechanism. We use an entire TIR band to add only one piece of information in the troposphere. Assuming the CO2 and CH4 partial column-averaged dry air mole fractions of the two individual layers of LT and UT are constant, we retrieve the difference between the partial column-averaged dry mole fractions of the lower troposphere (LT) and upper troposphere (UT) by combining TIR and SWIR spectra data simultaneously, constraining accurate total column density. The pressure-height ranges of LT and UT are taken as 1 -0.6 and 0.6 -0.2 of the retrieved surface pressure, respectively.
