Hi everyone,
A reminder that the final ATOC Colloquium of the fall semester will be
held in a hybrid format on *Friday, November 10 from 11a–12p MT over Zoom
and in SEEC S228. *This week's colloquium will feature a seminar from *Dr.
Jake Gristey (CIRES/NOAA CSL/LASP)* entitled, *"Shedding Light on Solar
Radiation Variability at Earth’s Surface*". The zoom login information and
an abstract for the colloquium are provided below. Please join us for
conversation beginning at 10:45am MT, and stay afterwards for a lunch
catered by Illegal Pete's.
We look forward to seeing you on Friday!

*Shedding Light on Solar Radiation Variability at Earth’s Surface *
Jake Gristey (CIRES/NOAA CSL/LASP)
Energy originating from the sun and reaching Earth’s surface, known as the
surface solar irradiance (SSI), is strongly modulated by ubiquitous shallow
cumulus clouds. The detailed 3D spatial structure of shallow cumulus
clouds, their rapid evolution, and coexisting aerosol all lead to complex
variability in SSI that has proven challenging to understand and predict.
In this talk, I will show how this SSI variability is encapsulated by the
bi-modal shape of the SSI probability density function (PDF), which is
robustly observed but only reproduced with 3D radiative transfer. Machine
learning is explored to construct a mapping between cloud and aerosol
properties, from large eddy simulation, and the corresponding SSI PDF, from
3D radiative transfer. This enables a drastic improvement in prediction of
SSI, relative to traditional 1D radiative transfer, with negligible
computational expense. I will also demonstrate how machine learning
inference techniques reveal an inordinately large importance of aerosol
between clouds. The findings have direct relevance for solar renewable
energy assessments and highlight the significance of neglecting 3D
radiative effects in atmospheric modeling.
