Remote Sensing Data Assimilation

We have developed a computational framework for data assimilation of Fraction of Photosynthetically Active Radiation absorbed by vegetation (FPAR) and Leaf Area Index (LAI) from the MODerate Resolution Imaging Spectroradiometer (MODIS) to constrain empirical temperature, light, moisture and structural vegetation parameters in a prognostic phenology model.   It uses the Ensemble Kalman Filter (EnKF) after …

Blue Marble Next Generation

The Blue Marble Next Generation (BMNG, 2005) is a cloud-free global satellite data set offering great spatial detail. It spans a longer data collection period than the original Blue Marble from 2000 and 2002. The original Blue Marble was a composite of four months of MODIS observations with a spatial resolution (level of detail) of …

Aura satellite launch & deploy

Aura is a earth observing satellite and it is part of NASA Earth Observing System (EOS). Aura’s four instruments study the atmosphere’s chemistry and dynamics. Aura’s measurements will enable us to investigate questions about ozone trends, air quality changes and their linkage to climate change. Aura’s measurements will provide accurate data for predictive models and …

Aqua satellite launch & deploy

Aqua, Latin for water, is a NASA Earth Science satellite mission named for the large amount of information that the mission is collecting about the Earth’s water cycle, including evaporation from the oceans, water vapor in the atmosphere, clouds, precipitation, soil moisture, sea ice, land ice, and snow cover on the land and ice. Additional …

Terra satellite launch & deploy

Terra is a multi-national, multi-disciplinary mission involving partnerships with the aerospace agencies of Canada and Japan. Managed by NASA’s Goddard Space Flight Center, the mission also receives key contributions from the Jet Propulsion Laboratoryand Langley Research Center. Terra is an important part of NASA’s Science Mission, helping us better understand and protect our home planet. I have created …
