Carbon-I related publications

Over the past two decades, remarkable advancements have been achieved in retrieving GHG data from space-based platforms. Lessons learned from the past play a crucial role in shaping our requirements and approach. We now know that a) very high spectral resolution (<1 nm) is not always necessary (Cusworth et al., 2019; Jongaramrungruang et al., 2021; A. Thorpe et al., 2014), b) the humid tropics yield far less reliable retrievals than previously anticipated at km-scale resolutions, c) high spatial resolution provides attribution, enables direct ground-truthing of remote retrievals, and is the only way to obtain more cloud-free data in the humid tropics. This list of papers is far from complete and will be updated in the near future.

Carbon-I leverages the advances made by previous dedicated satellite missions such as SCIAMACHY (C. Frankenberg et al., 2005), GOSAT, and OCO-2. In addition, we merge the advantages of high spatial resolution, which has now enabled revolutionary measurements of gas plumes, leading to actionable results (A. Thorpe et al., 2014). Our retrieval and point flux inversion approach is based on many publication from Carbon-I team members, e.g. Jongaramrungruang et al. (2019), Jongaramrungruang et al. (2021), Jongaramrungruang et al. (2022), D. R. Thompson et al. (2016), D. Thompson et al. (2016), Christian Frankenberg et al. (2016), Ayasse et al. (2018), Borchardt et al. (2020), Cusworth et al.
