11/22/2022 Kamal Aryal’s first article is published in Applied Optics as an Editors’s Pick

UMBC Physics PhD student Kamal Aryal, his PhD advisor Pengwang Zhai and their collaborators from NASA Goddard Space Flight center has recently published their work in Applied Optics. In this work, they have developed machine learning models based on Neural Networks which can be used to get the vertical profile of Instantaneous Photosynthetically Available Radiation (IPAR, and corresponding diffuse attenuation coefficients) from surface to euphotic zone depths in global oceans under a wide range of atmospheric and oceanic conditions. These models have high accuracy compared to existing semi-analytical models with significant superiority especially in coastal oceans.

IPAR regulates the amount of photosynthesis by phytoplanktons which plays a major role in fixing atmospheric carbon dioxide inside oceans. Their work has been highlighted in Applied Optics as an Editor’s pick.
