UMD SKYCAM Project Deploys Sky Imagers in Antarctica

Researchers from the Department of Geographical Sciences in collaboration with NASA Goddard Space Flight Center (GSFC) have deployed two sky imagers in Antarctica. This deployment is part of the SKYCAM project, led by Dr. Eric Vermote (NASA/GSFC, Emeritus Research Professor), aimed at establishing a global network of ground-based sky imagers for the study and characterization of clouds. 

“The SKYCAM project seeks to improve our understanding of clouds, their influence on remote sensing data, and to help enhance current cloud detection and characterization methods” says Dr. Andrés Santamaría-Artigas, a research scientist on the SKYCAM team. 

Clouds pose a major obstacle in optical remote sensing of the surface as they limit the number of useful observations made. Study of the data provided by SKYCAM will help address these challenges, as well as provide insights on cloud characterization with implications for global climate modeling, crop yield estimation, solar energy production and more. A proof-of-concept paper on utilizing sky imagery was published in 2021 in the International Journal of Applied Earth Observation and Geoinformation.

The SKYCAM field instruments, developed by UMD and NASA, take images at defined times and send them back to UMD for processing. Below is time-lapse footage from one of the sky imagers deployed at the Princess Elisabeth Station in Antarctica, in collaboration with the Royal Belgian Institute of Natural Sciences.

This deployment is of great interest to the project, as distinguishing between clouds and snow can be a significant challenge for remote sensing. Furthermore, it will allow testing of the instruments in one of the planet's most extreme environments.

The deployment of SKYCAM in Antarctica is the latest in a series of collaborations with national and international researchers and is part of the new International Center for Geospatial Innovation in the Department of Geographical Sciences. The SKYCAM team has already installed instruments at Goddard Space Flight Center (Maryland, USA), University of Valencia (Valencia, Spain), Sapienza University (Rome, Italy), and Sao Paulo University (Sao Paulo, Brazil).
