Biospheric Sciences - 618

Mission

Biospheric Sciences is a part of the Hydrospheric and Biospheric Sciences located at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Biospheric Sciences studies terrestrial ecosystems and their interactions with the atmosphere using multiscale remote sensing, modeling, and advanced analytical techniques.

Biospheric Sciences Laboratory studies terrestrial ecosystems and their interactions with the atmosphere using multiscale remote sensing, modeling, and advanced analytical techniques. Specifically:

  1. develops and utilizes satellite remote sensing, aircraft and ground instruments to measure variables that describe the temporal and spatial dynamics of natural ecosystems as well as human impacts on these systems, especially the vegetation condition (e.g., land cover, height, biomass, photosynthetic capacity), soils (e.g., soil condition and type), and links to atmospheric constituents (e.g., aerosols, CO2;
  2. develops mathematical models that use space-borne, airborne and ground observations to predict land surface conditions and processes related to rates of vegetation, soil, and atmosphere exchanges (e.g., radiation, heat, water, greenhouse gases, net primary productivity);
  3. acquires, produces, and distributes comprehensive, integrated land data sets incorporating ground, airborne, and/or satellite observations to facilitate model development and validation;
  4. ensures the scientific integrity of new Earth remote sensing systems to improve space-based Earth observation; and
  5. performs research which leads to the definition and development of new technologies, sensors, and missions. Through the above activities, assesses and predicts environmental changes due to natural and anthropogenic processes at local to global scales.

Research Highlights: January

Landslides within the Larch Dominant Permafrost Zone of Central Siberia

Figure 1

Landslides are frequently observed on south facing along rivers in central Siberia. The frequency of landslides has increased over past decades and is correlated positively to precipitation, temperature, as well as equivalent of water thickness anomaly (EWTA, measured in mm) from the GRACE mission. Impact of landslides on boreal forests and water quality needs to be better understood.

Noojipady. Praveen Noojipady (618/ESSIC) received his PhD in Geographical Sciences from the University of Maryland, College Park during the 2016 winter graduation (photo attached). Praveen was co-advised by Doug Morton (618), and his dissertation focused on ecosystem degradation and the interactions between climate variability and land management in the Southwest US, Brazil, and Southeast Asia.
