Abstract:
Remote sensing relies on a complex workflow to derive surface reflectance and higher-level products from at-sensor radiances. At each stage of this workflow, various sources of uncertainty emerge that are related to instrument noise, sun-sensor geometry, atmospheric conditions, the inversion or retrieval algorithm, and the product algorithm itself. Quantifying the sources of uncertainty within a simulation framework can help support mission design and optimize architectural configurations to reduce risk and to provide robust products to the science and applications community. An End-to-End Traceability simulator is currently in development for the NASA Surface Biology and Geology (SBG) Designated Observable to contribute in the assessment of measurement objectives and potential instrument configurations. “Modeling End-to-End Traceability in support of SBG”, or MEET-SBG, consists of four components that include local to global uncertainty quantification, cover hyperspectral visible to shortwave infrared (VSWIR) wavelengths and multispectral thermal infrared (TIR) emissions, and considers a multi-dimensional space of viewing conditions for a variety of research focal areas. Here we will present examples for each component, discuss their synergies for combining VSWIR and TIR, and how MEET-SBG contributes to the design and evaluation of the SBG architecture study.
