Research Interests Molly E. Brown, PhD My research contributes to NASA’s mission: ‘to advance and communicate scientific knowledge and understanding of the earth, the solar system, and the universe’. Two NASA earth science questions are at the center of my work: ‘How does the earth system respond to natural and human-induced changes?’ and ‘What are the consequences of change in the earth system for human civilization?’ To explore these questions, I conduct research in four areas: data fusion to develop long term data records of vegetation dynamics for carbon cycle and terrestrial ecosystem modeling; research to develop science data and analysis for societal applications; modeling of land cover and land use in the context of climate variability; and the development of models and methods that enable the quantification of the impact of climate change on human economic and political systems. Ongoing projects include:
- Developing new methods to integrate remote sensing data into econometric and food security models to improve the understanding of the effect of weather and climate on society;
- Improving methods to fuse remote sensing data observations of vegetation from multiple sensors;
- Working with local, national and international organizations to incorporate Earth science data and models to improve hazard early warning and understand of the threats of climate change;
- Communicating the impacts of climate change and variability to private and government land managers in Maryland, particularly on forest resources.
