What kind of MODIS data are available?
There are several composite MODIS vegetation products. Sixteen-day composites are available at 250 m, 500 m, 1 km, and 0.05 degree resolutions. There are also monthly composites with 1 km, and 0.05 degree resolutions.

What is the difference between Aqua and Terra?
The only difference is the data input. Terra circles a morning orbit and Aqua an afternoon orbit, which causes differences in solar zenith angle (also sensor view angle and azimuth angles) for daily MODIS images. According to my experience, both products perform very similarly for vegetation change detection.
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.
How often is MODIS data updated?
MODIS fire detection data and products are continuously updated and published year round to provide temporal and spatial coverage for the variable fire conditions that occur year round on the North American continent. MODIS data are acquired and processed typically within one hour of acquisition.

Is Aqua Terra a dress watch?
Striking the balance between everyday wear and elegant dress watch, the Aqua Terra is the perfect choice for those people looking for one watch for all occasions.
What is Aqua MODIS?
MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) 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.
What does MODIS stand for?
Moderate Resolution Imaging Spectroradiometer
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a payload imaging sensor built by Santa Barbara Remote Sensing that was launched into Earth orbit by NASA in 1999 on board the Terra (EOS AM) satellite, and in 2002 on board the Aqua (EOS PM) satellite.
