Extended Mission Support for the Earth Surface Mineral Dust Source Investigation (EMIT-Ext)

Dr. Roger N. Clark is a science co-investigator for the Earth Surface Mineral Dust Source Investigation (EMIT) and will support the Principal Investigator, Dr. Robert O. Green. In this phase of the EMIT mission, Dr. Clark will focus on continued calibration, validation, and monitoring of the EMIT imaging spectrometer instrument performance on the International Space Station as well as on the calibration and validation of the data products produced by the EMIT science and mission team for the Earth science and applications community. Specifically, Roger Clark will perform the following:

1. Work with the other members of the EMIT science and mission team to continually assess and track the calibration and validation performance of the EMIT imaging spectrometer on the International Space Station.

2. Support calibration, validation, and assessment of products delivered to the Earth science and applications community through the NASA Land Processes Distributed Active Archive Center (LP DAAC).

3. Dr. Clark will participate in weekly science team virtual tag-ups to track imaging spectrometer performance and in yearly science and applications team meetings.

4. Support validation of Tetracorder mineral mapping products acquired through time and spatially around the Earth in coordination with the EMIT mission team members and in support of the Earth science and applications community.

5. Provide detailed support to the EMIT mission team for refinements to the EMIT version of the Tetracorder algorithm for mineral identification based on the spectra measured by EMIT. Refinements will include necessary code and expert system updates as needed within budget to improve identification and mapping accuracy.

Reports will be sent to Dr. Robert Green at JPL. Work will be conducted primarily at Planetary Science Institute. These resources will support the funding for Dr. Roger Clark’s time and support to the EMIT project office at JPL as well as attendance at planned science team meetings.
