Instrument Details
The CarbonFOX instrument is based on MethaneSAT heritage and is built by the same Ball Aerospace team (now part of BAE Systems) using processes successfully used to deliver OMPS, OLI, TEMPO, and CALIPSO.
CarbonFOX is a pushbroom imaging spectrometer with high spatial resolution (to capture plumes) and high spectral resolution (to quantify diffuse fluxes) to illuminate the carbon processes.
The CO2/CH4 Imaging Spectrometer
• Spectral Range: 1596 - 1678 nm
• Spectral Resolution: 0.23 nm (FWHM)
• Spectral Sampling: 3 pixels per FWHM
• Avg SNR (continuum) > 152 at reference of 25% surface reflectance and 45° solar zenith angle, single pixel
• Dynamic Range: SNR of 10.5 to 384 for scene radiance of 0.36 to 64 W/m2/μm/sr
The O2 Imaging Spectrometer
• Spectral Range: 734 - 773 nm
• Spectral Resolution: 0.12 nm (FWHM)
• Spectral Sampling: 3 pixels per FWHM
• Avg SNR (continuum) ≥ 184 at same reference as above, single pixel
• Dynamic Range: SNR of 5.6 to 378 for scene radiance of 0.79 to 264 W/m2/μm/sr
CarbonFOX images the full globe every 4-9 days depending on latitude and with a wide enough swath (~250 km) to quantify fluxes for entire cities and the spatial and spectral precision to resolve carbon fluxes for neighborhoods
