Solar forecasting and cloud observations for NREL workshop

To do solar forecasting well requires the ability to model the impacts of clouds. Different cloud types impact the amount of energy produced by a solar farm in significant ways...whether it's a haze in the sky, fog near the ground, or thick cumulus clouds that cause dark shadows and block more solar radiation, to name a few. Thus a skilled solar forecast should consider solar irradiance and transfer.

This week I appreciated the opportunity to present AER's approach to "Surface Solar Irradiance: Cloud Observations and Radiative Transfer Modeling", during the "Short-Term and Day-Ahead Forecasting" portion of the Solar Resources and Forecasting Workshop hosted by the National Renewable Energy Lab (NREL).
