SatERR is a bottom-up approach, where the four types of errors including measurement, preprocessing, observation operator, and representativeness errors are generated from sources and forward propagate through radiances, science products, and data assimilation systems. This approach can quantify and partition errors and uncertainties in science products, and capture leading features of the most important errors in a statistical sense for data assimilation.

Leveraging Satellite Observations with a Comprehensive Simulator

Satellite observations are vital for weather forecasts, climate monitoring, and environmental studies. In recent years, there has been a concerted effort to develop methods for quantifying and representing errors associated with satellite observations. ESSIC scientist John Xun Yang has led a team of scientists in the creation of an error inventory simulator, the Satellite Error Representation and Realization (SatERR).

Hydropower: Worldwide Transition to Low-Carbon Energy Could Threaten Ecologically Sensitive Rivers

The global transition towards a low-carbon future could substantially accelerate hydropower deployment in ecologically sensitive rivers, according to a new study led by researchers at the University of Maryland’s Earth System Science Interdisciplinary Center (ESSIC) in collaboration with Pacific Northwest National Lab (PNNL)’s Joint Global Change Research Institute (JGCRI) and Tufts University. Published in Nature Sustainability, the paper analyzes the future hydropower expansion in the world’s 20 most ecologically sensitive rivers under different socio-economic and energy sector development scenarios.

Can meteorologists save the Chesapeake Bay?

When the nation’s leading experts in weather, water, and climate gather in Baltimore later this month for the annual conference of the American Meteorological Society (AMS), they will get a close-up view of the region’s fragile environment. The Chesapeake Bay area is under siege from a myriad of threats that are becoming more urgent with climate change, and its future economic and ecological vitality may depend in part on the ability of scientists to map out solutions to the bay’s complex and multiple stressors.
