How many MODIS satellites are there?
There are two MODIS sensors in Earth orbit: one on board the Terra (EOS AM) satellite, launched by NASA in 1999; and one on board the Aqua (EOS PM) satellite, launched in 2002.
What does MODIS satellite do?
MODIS helps scientists determine the amount of water vapor in a column of the atmosphere and the vertical distribution of temperature and water vapor—measurements crucial to understanding Earth’s climate system.
What is MODIS satellite imagery?
MODIS stands for Moderate Resolution Imaging Spectroradiometer. It has 36 spectral bands, 250-1000 meter resolution and averages 2-day revisit period. Because of this versatility, MODIS has changed how we understand our land, ocean, and atmosphere.
Is MODIS still operational?
The MODIS instrument is operating on both the Terra and Aqua spacecraft. It has a viewing swath width of 2,330 km and views the entire surface of the Earth every one to two days. MODIS Level 1 and atmosphere products are available through the LAADS web.
Is MODIS multispectral?
Moderate Resolution Imaging Spectroradiometer sensor, also known as MODIS, is a key multispectral sensor that is flown aboard NASA’s Terra and Aqua satellites. Both satellites view the Earth’s entire surface every one to two days at a moderate resolution (1/4 to 1 kilometer) (NASA Goddard Space Flight Center, 2001).
What does MODIS stand for?
Moderate Resolution Imaging Spectroradiometer
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.
What spectral bands does MODIS detect?
MODIS is a scanning spectroradiometer that collects imagery in 36 spectral bands from the shortwave visible spectrum (0.41 microns) to the longwave infrared spectrum (14.2 microns). MODIS sensors are flying in sun-synchronous polar orbit on the NASA Terra and Aqua satellites.
What kind of company is MODIS?
Modis delivers cross-industry expertise in technology and digital engineering consulting, talent services and skilling to enable digital transformation and accelerate innovation.
What is MODIS on a fire map?
What is MODIS? MODIS is the Moderate Resolution Imaging Spectroradiometer. The MODIS instrument is a polar orbiting, high temporal, moderate spatial resolution sensor that acquires remote sensing data for monitoring the Earth’s land, ocean and atmosphere.
How accurate is MODIS?
The MODIS Land Science Team requires the geolocation accuracy to be 150 m (1σ), with an operational goal of 50 m (1σ) at nadir (Nishihama et al., 1997).
Is Modis and Adecco the same company?
Modis is part of the Adecco Group, the world’s leading HR solutions company and a Fortune Global 500 company.
Is Modis a good company?
Modis is a very good consultant company to have worked for. My assignments were very organized and well communicated on a weekly basis. Management was always nice and transparent.
What is the resolution of MODIS?
Data. The MODIS instrument is operating on both the Terra and Aqua spacecraft. It has a viewing swath width of 2,330 km and views the entire surface of the Earth every one to two days. Its detectors measure 36 spectral bands between 0.405 and 14.385 µm, and it acquires data at three spatial resolutions — 250m, 500m, and 1,000m.

How do I view MODIS images?
Welcome to the Image Section of the MODIS Web, where you can view the very latest in MODIS imagery as well as search an image collection that has been growing ever since MODIS first started acquiring data in February of 2000. The MODIS Image of the Day section highlights a new MODIS image every day.
How many spectral bands does MODIS have?
With its sweeping 2,330-km-wide viewing swath, MODIS sees every point on our world every 1-2 days in 36 discrete spectral bands. Consequently, MODIS tracks a wider array of the earth’s vital signs than any other Terra sensor.
