Biospheric Sciences - 618


Biospheric Sciences is a part of the Hydrospheric, Biospheric, and Geophysics 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: April

Ground Reflectance Intercomparison at Railroad Valley Playa

Kurtis Thome1, Jeff Czapla-Myers2, Brian Wenny3

(1:Biospheric Sciences Laboratory (618), 2:University of Arizona, 3:SSAI)

A joint campaign was organized by NASA/GSFC and University of Arizona at Railroad Valley Playa, Nevada May 1 to May 6, 2018 to refine collection approaches and develop guidelines for future surface reflectance intercomparisons and validations. Participants included commercial, education, and government participants from three countries with representatives from the calibration teams of all three Terra imagers.

Brown Bag Seminars

Brown Bag Seminars are initiated as an informal forum to present your new work or updates to your 618 colleagues.

Seminars are typically held on Wednesdays between 12:00 and 1:00 PM.

Next Seminar: Dr. Petr LukeŇ°, Wednesday, November 28th, 2018

Please check the calendar for a list of past and upcoming seminars.
