MODIS

Overview

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (originally known as EOS AM-1) and Aqua (originally known as EOS PM-1) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on January 3, 2017.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on January 3, 2017. It was loud and brief. For a few minutes around 9 p.m. on January 3, 2017, Alaska’s Bogoslof volcano let loose an explosion. According to the Alaska Volcano Observatory, cloud-top temperatures indicate the volcanic plume may have reached...

The Operational Land Imager (OLI) on the Landsat 8 satellite captured this natural-color image of a smoke plume south of Río Colorado on December 29, 2016.
The Operational Land Imager (OLI) on the Landsat 8 satellite captured this natural-color image of a smoke plume south of Río Colorado on December 29, 2016. Dense smoke rose above a rash of wildfires in the Pampas region of Argentina in late December 2016 and early January 2017. Over the past month, roughly two dozen fires have spread across the rural landscape. The blazes were likely started by thunderstorms that followed a stretch of hotter-than-average weather, according to ...

 On October 9, 2016, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image of floodwaters laden with sediment pouring out from several rivers in North Carolina and South Carolina.
Though its winds had weakened as it moved north, Hurricane Matthew delivered record-breaking rainfall to parts of Georgia, South Carolina, North Carolina, and Virginia. In many coastal areas, the storm dumped well over 12 inches (30 centimeters) of water. On October 9, 2016, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s ...

The Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA’s Terra and Aqua satellites acquired this image of the ash plume at 11:45 a.m. Alaska time (21:45 Universal Time) on March 28, 2016.
The Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA’s Terra and Aqua satellites acquired this image of the ash plume at 11:45 a.m. Alaska time (21:45 Universal Time) on March 28, 2016. In late March 2016, Pavlof volcano on the Alaskan Peninsula began erupting again for the first time since November 2014. Alaska’s most active volcano has erupted six times since 1996 and 21 times in the past 50...

Four Fires Plague Southern California
Dry and hot weather conditions in the southern part of California as well as a spate of careless humans and lightning strikes have created an environment rife for fire outbreaks.  Four very large fires are currently causing havoc in the area and NASA's Suomi NPP satellite's VIIRS (Visible Infrared Imaging Radiometer Suite) instrument captured this image of all four fires on August 23, 2016. Actively burning areas, detected by MODIS’s thermal bands, are outlined in red.  The...

Sand and Soberanes Fires Still Blazing in California
The Sand and Soberanes fires in California continue to blaze, however, the Sand Fire (lower fire) is 65% contained whereas the Soberanes Fire (upper fire) remains only 10% contained.   The Soberanes fire activity increased due to lower humidity and higher temperatures, which continues to present as a challenge in controlling the fire. A private hired equipment bull dozer operator was fatally injured last evening (July 26, 2016). A State of Emergency has been declared by...
