Abstract

Aircraft measurements of carbon dioxide and methane over Tsukuba (36.05° N, 140.12° E) (February 2010) and Moshiri (44.36° N, 142.26° E) (August 2009) were made to calibrate ground-based high-resolution Fourier Transform Spectrometers (g-b FTSs) and to compare with the Greenhouse gases Observing SATellite (GOSAT). The aircraft measurements over Tsukuba in February 2010 were successful in synchronizing with both the g-b FTS and GOSAT for the first time. Airborne in situ and flask-sampling instruments were mounted on the aircraft, and measurements were carried out between altitudes of 0.5 and 7 km to obtain vertical profiles of carbon dioxide (CO_2), methane (CH_4), and other gaseous species. By comparing the g-b FTS measurements with the airborne measurements, the column-averaged dry air mole fractions of CO_2 (X_(CO_2)) and CH_4 (X_(CH_4)) retrieved from the g-b FTS measurements at Tsukuba were biased low by 0.33 ± 0.11% for X_(CO_2) and 0.69 ± 0.29% for X_(CH_4). The g-b FTS values at Moshiri were biased low by 1.24% for X_(CO_2) and 2.11% for X_(CH_4). The GOSAT data show biases that are 3.1% ± 1.7% lower for X_(CO_2) and 2.5% ± 0.8% lower for X_(CH_4) than the aircraft measurements obtained over Tsukuba.
