Science Center Objects

The EROS Moderate Resolution Imaging Spectroradiometer (eMODIS) Land Surface Temperature (LST) collection is based on the Moderate Resolution Imaging Spectroradiometer (MODIS) data acquired by the National Aeronautics and Space Administration's (NASA) Earth Observing System (EOS).

Moderate resolution remote sensing provides a means for operational monitoring communities to develop historical trend information and use near real-time deviations from temporal averages to identify areas of change. High quality, consistent and well-calibrated satellite measurements are needed to detect and monitor changes and trends, especially in vegetation patterns useful for drought, crop yield, phenology and fire potential studies.

The eMODIS LST collection is based on the Moderate Resolution Imaging Spectroradiometer (MODIS) data acquired by the National Aeronautics and Space Administration's (NASA) Earth Observing System (EOS).  Even though MODIS data are beneficial in vegetation studies, there have been usability issues encountered with the reprojection, file format and sub-setting. Therefore, eMODIS was developed to specifically address these issues.

The eMODIS LST is a 10-day data composited data set using the AQUA MODIS sensor only.  Expedited (near real-time) production runs every five days for the 10-day products. There is no expedited production over Alaska.  Because each of the composites are created from a varying number of images, the eMODIS composites include acquisition files to identify which of the possible inputs were used to populate the final composite.  Product generation information can be found in the Open File Report – eMODIS:  A User-Friendly Data Source.  The metadata accompanying the data files summarize geographic bounds, projection parameters and product contact information.  The data has Global coverage and is available in GeoTIFF format, Geographic projection, and 250-meter resolution.
