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.

For much of March and April 2020, satellites have detected signatures of heat and smoke from fires burning in northwestern Venezuela. Some of them burned in and near Ciénagas del Catatumbo National Park, a flat swampy area west of Lake Maracaibo known for its rainforests full of unusual plant and animal life.

In December 2019 and January 2020 Australia has experienced widespread and severe fires causing extensive damage to the local ecosystem and communities and blanketing the surrounding regions in smoke. By studying data from multiple Earth-observing satellites and different types of sensors, NASA researchers can get a more comprehensive understanding of the extent of the fires and their impact to the surrounding communities.

On December 16th, 2019 NASA’s Terra satellite flew over the eastern coast of Australia, capturing 3D data on the height of smoke plumes emanating from the fires with its Multi-angle Imaging SpectroRadiometer (MISR) instrument. Using data from this overpass, the NASA Disasters Program in collaboration with the Active Aerosol Plume-height (AAP) project has developed the first ever interactive 3D visualization of MISR fire plume-height data, which demonstrates the new 3D capabilities of the NASA Disasters Mapping Portal. ...

The devastating fires in southeastern Australia have renewed focus on the dangers that extreme drought and heat can pose to society. Last week, fires erupted near populated areas in Victoria and New South Wales with destructive effects, resulting in one of Australia’s largest evacuations. NASA’s CALIPSO satellite provided data for a new animation that showed the aerosols generated from the smoke has spread high into the atmosphere and far to the east over the Pacific Ocean.

The six-day-old Camp Fire has already attained the unfortunate title of California's deadliest fire. The Camp Fire has already led to 42 deaths with a number of residents still unaccounted for. It is also the most destructive in California history as well with over 7,000 structures destroyed by the blaze. The fire began on Nov. 08, 2018 and has grown to a staggering 125,000 acres in just under a week. The cause of this blaze is still under investigation. California state regulators are investigating two utility companies that reported incidents close in time and location to the start of...

Sea surface temperatures in the tropical Pacific Ocean on August 21, 2018 compiled by Coral Reef Watch, which blends observations from the Suomi NPP, MTSAT, Meteosat, and GOES satellites, and computer models. 
Multiple threatening tropical cyclones spun over the Pacific Ocean in August 2018. In the northwest Pacific basin, typhoons Soulik and Cimaron took aim at Japan and the Korean Peninsula. Then Hurricane Lane lined up in the tropical Pacific for an encounter with the Hawaiian Islands. At 10:45 a.m. Hawaii Standard Time (20:45 Universal Time) on August 21, 2018, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image of Hurricane Lane. Around that time, Lane was a powerful category 4 hurricane with...

On August 31, 2017, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image of the Texas coast and the Houston metropolitan area. Note the brown rivers and bays, full of flood water from Hurricane Harvey. Along the coast, muddy, sediment-laden waters from inland pour into a Gulf of Mexico that also was churned up by the relentless storm.

MODIS true-color image of floods in Quebec from May 8, 2017.
Its been pretty overcast over much of eastern Canada the past several days - all of Quebec, and eastern Ontario, as in the above MODIS true-color image. Clouds have shifted slightly, but not dramatically over the past few days. Central Ontario is clear, but we dont see much there - there's a spot of "flooding" north of Toronto (by Barrie), but this is simply a wetland that is not in the MOD44W layer so shows up as flood.

Flood extent map from the 2017 floods in Argentina.
This is a draft map using two (Terra and Aqua) NASA MODIS WorldView scenes from April 11, 2017. Water was classified using an "isodata" unsupervised classification method (7-17 classes, three iterations, three classes were combined into one "water" class). A before scene is shown above for comparison purposes, but no change detection approach has been used so far. There are abundant "false water" areas shown; this map will be revised to remove these errors. Data processing of Sentinel 1 SAR scenes is in progress. Many rivers in this dry region of the Pampas are ephemeral and ofter without...

Aqua true-color image overlaid with active-fire detections, shown in red, take from MODIS (onboard Terra and Aqua) and VIIRS (onboard Suomi-NPP), showing smoke streaming from wildfires in Guatemala on April 1st 2017.
Fires started to burn in early March in the protected regions of Sierra del Lacandón National Park (also Laguna del Tigre), which is located in the tropical rain forest in the north west of Guatemala.   Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS) data are being used to locate fire lines that are difficult to see from the ground, and these data are also being used to analyze long term fire trends.  One Guatemalan weekly report highlighted the improved value of VIIRS data to locate small fires and the valuable long–term...
