What is MODIS data used for?

In addition to recording the frequency and distribution of cloud cover, MODIS measures the properties of clouds such as the distribution and size of cloud droplets in both liquid water and ice clouds. MODIS also measures the properties of aerosols—tiny liquid or solid particles in the atmosphere.

Is MODIS still active?

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. MODIS is succeeded by the VIIRS, which was first launched in 2011 aboard the Suomi NPP satellite.

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.

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.

Who uses MODIS?

6.4. MODIS is the main sensor board on the NASA EOS (Earth Observation System) series of satellites. Terra/MODIS began to collect data in 2000, and Aqua/MODIS started in 2003.

Does MODIS use active sensors?

Fire and Hot Spot Detection. The fire detection algorithm uses MODIS to detect active fires.

When was MODIS launched?

December 18, 1999
Introduction. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument is operating on both the Terra and Aqua spacecraft. The Terra satellite was launched on December 18, 1999 and the Aqua on May 4, 2002.

Is MODIS open source?

The MODIS Web Service is a tool that provides users with a means to order subsets of MODIS Land Products through standards based SOAP (Simple Object Access Protocol) established open source formats.

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.

Is MODIS active or passive?

passive sensors
Quickbird, WorldView, Landsat and MODIS are all passive sensors that measure only radiation emitted by the Sun and reflected or emitted by the Earth.

What is MODIS satellite data?

MODIS is an extensive program using sensors on two satellites that each provide complete daily coverage of the earth. The data have a variety of resolutions; spectral, spatial and temporal.
