abstract = {The prediction of sun-induced fluorescence (SIF) from
hyperspectral radiance has been identified as a corner stone
to assess plants’ photosynthetic efficiency remotely. It
is widely accepted that remotely sensed SIF offers great
potential for a variety of applications. To provide such
estimates, top-of-canopy SIF products derived from passively
sensed radiance measurements of various airborne and
spaceborne sensors have been developed over the last
decades. To date, however, physically based SIF retrieval
schemes require a prohibitive use of computationally costly
radiative transfer simulations especially when used in
complex observational conditions such as in hilly terrain.
In this contribution we report on our on-going work to
develop a lightweight self-supervised neural network to
retrieve SIF in the O$_2$-A absorption band of HyPlant
acquisitions. We aim at a tight integration of a physical
radiative transfer model with the network to ensure
physically sound predictions by leveraging large scale
simulation and emulation of HyPlant at-sensor radiance
observations. We report on first results that we achieve on
a dedicated data set.},
