Description
While first detections of atmospheric species were based on medium-to low resolution data from space, ground-based facilities have majorly contributed to our understanding of these far-away worlds since then.
To a large part this is owed to the use of high-resolution spectroscopy, which allows us to identify the resolved lines of metals and molecules in the optical and infrared wavelength regions using cross-correlation with synthetic models or studies of isolated lines. The success of these methods on ultra-hot to warm exoplanets have inspired the community to design instruments for the extremely large telescope facilities with the goal to extend these studies to the atmospheres of rocky worlds in the future. But not all our dreams for the bright future of exoplanet atmospheres are based on high-resolution instrumentation.
In parallel, studies at lower resolution have been continued both from the ground as well as from space. Especially with the recent launch of JWST and the planned launch of ARIEL in 2029 we can expect space based medium resolution studies to be a main driver of the advancement of our field in the next decades.
With the same planets being observed at different resolutions and thus analyzed with different methods the question emerges of how these different kinds of data relate to each other. In this talk I will focus on the individual challenges and differences presented by low and high-res data and the methods used to analyze them. I will address in which capacity the information derived from them is equivalent and/or complementary and what we can hope to gain when using both methods in unison.
