Novel approaches to atmospheric trace gas remote sensing

Novel approaches to atmospheric trace gas remote sensing

Atmospheric trace gases have been measured since decades at the IUP. However, still new technologies and new applications of proven ideas can vastly improve the performance of the instruments required for such measurements. This is shown in two new publications by the IUP members Ulrich Platt, Jonas Kuhn, Nicole Bobrowski, Thomas Wagner, and Thomas Leisner:

These address the replacement of a single (large) spectrograph by arrays of scaled-down spectrographs in order to improve the performance of remote sensing instruments while at the same time reducing weight and volume by orders of magnitude (https://doi.org/10.5194/amt-14-6867-2021). Another approach aims at implementing spectrographs with significantly higher spectral resolution (picometres instead of nanometres), while maintaining instrument mobility (compactness and stability) and light throughput (https://doi.org/10.5194/amt-14-7873-2021). Both approaches have great potential to enhance the quality of atmospheric observations (e.g. higher spatial and temporal resolution, measurement of further gas species) in the near future.
