Abstract:
Mobile remote sensing observations from ship-
borne platforms offer a unique opportunity for validating
satellite observations and sampling plumes of greenhouse
gases and short-lived air pollutants from the world’s highly
populated coastal megacities and industrial sites. Here, we
demonstrate the capabilities of a shipborne setup that com-
bines a sun-viewing EM27/SUN Fourier transform spec-
trometer for the shortwave-infrared spectral range with a
direct-sun DOAS (Differential Optical Absorption Spec-
troscopy) spectrometer for the visible spectral range, en-
abling simultaneous measurements of the column abun-
dances of carbon dioxide (CO2), methane (CH4), carbon
monoxide (CO), and nitrogen dioxide (NO2). For several
months in 2023 and 2024, the instruments were operating
autonomously on a commercial vessel traveling back and
forth along the coast of Japan. We show that, for CO2, CH4,
and CO, precision and repeatability comply with the stan-
dards of the Collaborative Carbon Column Observing Net-
work (COCCON). Further, for a case study in the vicinity of
Nagoya, we demonstrate the scientific leverage of this mobile
