Optimal Estimation for Combined Retrievals of Surface and Atmosphere: Algorithms, Results, and Open Source Software

Description:This is a sequence of hands-on lab experiences using open source code for imaging spectrometer data analysis. Topics include visualization, atmospheric correction, and surface property estimation with rigorous uncertainty propagation. These modules will be offered as independent tutorial sessions in conjunction with the WHISPERS 2019 meeting. The sessions are open to all attendees, who can attend any combination in any order as desired.

The tutorials will use the open-source ISOFIT codebase ( for atmospheric correction, and OpenSPEC for visualization capability similar to that provided in the ENVI interface. Tutorial materials are also available as open source resources for participants to use in their own courses.
