<abstract>
<p>Atmospheric column-average methane mole fractions measured with ground-based
Fourier-transform spectroscopy near Saint Petersburg, Russia
(59.9° N, 29.8° E, 20 m a.s.l.) are compared with similar
data obtained with the Japanese GOSAT (Greenhouse gases Observing SATellite)  in the years 2009–2012. Average
CH&lt;sub&gt;4&lt;/sub&gt; mole fractions for the GOSAT data version V01.xx are
&amp;minus;15.0 ± 5.4 ppb less than the corresponding values obtained from
ground-based measurements (with the standard deviations of biases
at 13.0 ± 4.2 ppb). For the GOSAT data version V02.xx, the average values
of the differences are &amp;minus;1.9 ± 1.8 ppb with   standard deviations
of 14.5 ± 1.3 ppb. This verifies that FTIR (Fourier transform infrared) spectroscopic observations near
Saint Petersburg have similar biases with GOSAT satellite data as FTIR
measurements at other ground-based networks and aircraft CH&lt;sub&gt;4&lt;/sub&gt;
estimations.</p>
