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 does the MODIS instrument do?
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a key instrument onboard the Earth Observing System (EOS) Terra and Aqua platforms, designed to monitor the Earth's atmosphere, ocean, and land surface with a set of visible, NIR, MIR, and thermal channels.
Is MODIS still operational?
The MODIS instrument is operating on both the Terra and Aqua spacecraft.
What is MODIS in remote sensing?
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a satellite-based sensor used for earth and climate measurements. … The MODIS instruments were built by Santa Barbara Remote Sensing.
How does MODIS collect data?
As the Aqua and Terra satellites orbit the earth, their MODIS instruments collect imagery of the same area on Earth approximately three hours apart. The entire Earth's surface is imaged every one to two days, and the sensors work in tandem to optimize cloud-free surface viewing.
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.
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 projection is MODIS data in?
Sinusoidal projection The data are provided in the HDF-EOS format. MODIS data at version 4 and above use the Sinusoidal projection with the WGS84 datum.
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.
