Collection Overview

Missions

The NASA Earth Observing System (EOS) program comprises a series of polar-orbiting and low-inclination satellites designed to monitor and understand Earth systems through long-term global observations.

MODIS

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument is operating on both the Terra and Aqua spacecraft. It views the entire surface of the Earth every one to two days. MODIS data contribute to a range of land and water application areas including wildfire monitoring, temperature and emissivity changes, land surface change, vegetation and ecosystem dynamics, natural disasters, and agriculture studies. Learn more about MODIS data.

ASTER

Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data contribute to a wide array of global change-related application areas including vegetation and ecosystem dynamics, hazard monitoring, geology and soils, hydrology, and land cover change. The ASTER instrument is aboard the Terra satellite and is taskable and able to be scheduled for on-demand data acquisition requests. For more information on tasking ASTER please visit the ASTER JPL Website.

S-NPP VIIRS

Visible Infrared Imaging Radiometer Suite (VIIRS) is aboard the Suomi National Polar-orbiting Partnership (S-NPP). VIIRS observes the entire Earth’s surface twice each day, once during the day and once at night.. VIIRS data contribute to a range of land and water application areas including wildfire monitoring, temperature and emissivity changes, land surface change, vegetation and ecosystem dynamics, natural disasters, and agriculture studies. Generated in a similar format to MODIS, VIIRS data products aim to extend the data lifecycle of MODIS products. Learn more about VIIRS data.

ECOSTRESS

Principal Investigator: Simon Hook, NASA/Caltech Jet Propulsion Laboratory

The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) is aboard the International Space Station (ISS) and measures the temperature of plants to better understand how much water plants need and how they respond to stress. ECOSTRESS addresses three overarching science questions: How is the terrestrial biosphere responding to changes in water availability? How do changes in diurnal vegetation water stress impact the global carbon cycle? Can agricultural vulnerability be reduced through advanced monitoring of agricultural water consumptive use and improved drought estimation? ECOSTRESS uses a multispectral thermal infrared radiometer to measure the surface temperature. The radiometer obtains detailed images of the Earth’s surface that can provide information on the temperature of an individual farmer’s field. Learn more on the ECOSTRESS website.

FUTURE MISSIONS

GEDI
Principal Investigator: Scott Luthcke, NASA/ Goddard Space Flight Center

GEDI is a full-waveform lidar instrument that will produce detailed observations of the 3D structure of the Earth’s surface. GEDI will precisely measure forest canopy height, canopy vertical structure, and surface elevation which will enhance our understanding of global carbon and water cycle processes, biodiversity, and habitat. GEDI is the first of its kind to provide high resolution laser ranging observations optimized for lidar measurements of the Earth’s forests and topography at the highest resolution and densest sampling of any other lidar instrument in orbit. Data from GEDI will be archived and distributed by the LP DAAC in the future. Learn more about GEDI.
