SciGlob proposes the development of an optimized miniature spectrometer for improved trace gas monitoring and satellite validation.
The new spectrometer will be substantially superior to the ones currently used giving higher signal-to-noise ratio, having less stray light and better temperature stabilization, and also a more repeatable manufacturing and alignment process. This will significantly improve the accuracy for ground-based remote sensing trace gas retrievals.
Out of several design improvements, we consider the following items as the main innovative aspects of the proposed system:
The primary NASA application is that this spectrometer could be used in the NASA-developed Pandora Spectrometer System and hence incorporated in the Pandonia Global Network (PGN). This would improve the satellite calibration and validation (cal/val) activities for existing and upcoming satellite missions from NASA and collaborating agencies (PACE, TEMPO, GEMS, Sentinels).
All participants in the PGN (ESA, EPA, national and international institutions) will benefit from this development. This spectrometer could also be of interest to other US government agencies such as the DOE Office of Environmental Management or the Bureau of Ocean Energy Management for general applications ranging from agriculture, biology, chemistry, to general environmental research.
