Column-averaged volume mixing ratios of carbon dioxide and methane retrieved
from the Greenhouse gases Observing SATellite (GOSAT) Short-Wavelength
InfraRed observation (GOSAT SWIR XCO2 and XCH4) were compared with
the reference calibrated data obtained by ground-based high-resolution
Fourier Transform Spectrometers (g-b FTSs) participating in the Total Carbon
Column Observing Network (TCCON).
Preliminary results are as follows: the GOSAT SWIR XCO2 and XCH4
(Version 01.xx) are biased low by 8.85 ± 4.75 ppm (2.3 ± 1.2 %) and
20.4 ± 18.9 ppb (1.2 ± 1.1 %), respectively. The standard deviation
of the GOSAT SWIR XCO2 and XCH4 is about 1 % (1 σ) after
correcting the negative biases of XCO2 and XCH4 by 8.85 ppm and
20.4 ppb, respectively. The latitudinal distributions of zonal means of the GOSAT
SWIR XCO2 and XCH4 show similar features to those of the g-b FTS
data except for the negative biases in the GOSAT data. |
