dc.description.abstractAccurately capturing the evolution of episodic stratosphere-to-troposphere transport is critical due to the potential impacts on both climate and air quality. Until now, investigating associated spatiotemporal gradients in total column ozone (TCO) has primarily been the task of observations from polar-orbiting satellites as well as high-resolution models. We explore how a network of five ground-based Pandora spectrometer systems can be utilized in a similar fashion. The passage of a strong mid-latitude cyclone in March 2018 and its associated stratospheric intrusion is used as a case demonstrating the ability of networked Pandora observations to contextualize these regions of transport across space and time. Results show that the high temporal resolution of Pandora observations and the networked approach were able to resolve increases in TCO associated with stratosphere-to-troposphere transport and to capture the spatial context of the chosen episode. The use of networked Pandora observations shows promise for additional transport studies and for supporting future geostationary atmospheric composition satellite missions and modeling efforts.en_US
dc.description.sponsorshipThis work was conducted under the NASA Pandora Project with funding support from the NASA Tropospheric Chemistry Program. Siting of the Pandora system at CCNY was supported by NASA grant number 80NSSC18K1035 with additional support from NOAA Earth System Sciences and Remote Sensing Technologies award number NA16SEC4810008. Analysis of networked Pandora data is only possible thanks to the involvement and support of global PGN members, Lena Shalaby (JCET/GSFC) and Alexander Dimov (SSAI/GSFC) from the NASA Pandora Project, as well as M. Müller (LuftBlick) from ESA Pandonia. Additionally, J. Robinson would like to thank Krzysztof Wargan (SSAI/GSFC) for useful discussions surrounding MERRA-2 data handling and analysis.en_US
