In this presentation I will discuss our group's work developing the first satellite-based measurement of atmospheric isoprene, using the CrIS infrared sounder. These measurements provide new insights into the distribution and drivers of global isoprene emissions. When combined with concurrent space-based measurements of atmospheric formaldehyde (an isoprene oxidation product) and nitrogen dioxide, the data also allow us to test understanding of isoprene oxidation and its impacts on atmospheric OH across NOx regimes. I will also highlight our recent efforts developing the next-generation isoprene retrieval, with improved signal-to-noise that allows us to resolve fine-scale spatial and temporal variability in atmospheric isoprene to a greater degree than was previously possible.
