USGS EROS Teams Offer Replacement for Expiring Satellite Vegetation Monitoring Datasets
By Earth Resources Observation and Science (EROS) Center
May 27, 2022
When the Moderate Resolution Imaging Spectroradiometer (MODIS) was first launched into low Earth orbit 24 years ago, it held the promise of daily and weekly vegetation monitoring data for a host of potential scientific applications.

MODIS data, available through NASA’s USGS EROS-based Land Processes Distributed Active Archive Center (LP DAAC), have since proven their worth many times over.
EROS MODIS Normalized Difference Vegetation Index (eMODIS NDVI) and eMODIS Global Land Surface Temperature (LST) data products, meanwhile, have allowed users to more easily apply MODIS data to operational science applications such as VegDRI and QuickDRI.
For years, the eMODIS NDVI and eMODIS Global LST products built at EROS have been a vital vegetation monitoring resource for a wide range of government, academic and commercial research teams.
However, the NASA Terra and Aqua satellites that carry MODIS sensors have nearly reached the end of their lifespan. This will soon bring an end to the era of MODIS data.
The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) and NOAA-20 satellites will serve as the successor to MODIS. VIIRS enables a new generation of operational moderate resolution-imaging capabilities, following in the footsteps of the Advanced Very High-Resolution Radiometer (AVHRR) on NOAA satellites, and MODIS on Terra and Aqua.
EROS began building EROS VIIRS, or eVIIRS, composites in 2021. The move came in anticipation of the end of the mission life for MODIS. Many users have already switched to eVIIRS composites.
EROS Center teams are now asking users to begin to switch your projects from eMODIS products to the comparable eVIIRS products as soon as possible.
EROS welcomes feedback from the user community on eVIIRS and encourages feedback to USGS EROS User Services.
The eVIIRS NDVI and Global LST composites are available on EarthExplorer (EE). VegDRI and QuickDRI production has transitioned to VIIRS sensor products, and users have been pleased with the results. Web viewers for Vegetation Dynamics Drought Viewer that host these and other products for monitoring drought in the contiguous United States are available in EE alongside eVIIRS NDVI and Global LST..
Please evaluate the eVIIRS products for future use. Barring any satellite data collection or processing issues, eMODIS products will be produced through the summer of 2022. Production of eMODIS products will cease by Oct. 1, 2022.

Eyes on Earth Episode 12 – Plant Health via Satellite (NDVI)
A farmer at the foot of a corn stalk can tell how well the plant is faring. That same farmer might survey his entire field for crop health. But assessing the health of crops or forests at regional, national, and international scales requires remote sensing, most often via satellite.

Eyes on Earth Episode 9 – Famine Early Warning
Nearly 85 million people around the world are currently considered “food insecure,” and that figure continues to grow. Remote sensing technology enables scientists to feed data into the Famine Early Warning Systems Network (FEWS NET), which in turn can issue alerts that guide the distribution of humanitarian aid.
