You can obtain MODIS Atmosphere products from the same LAADS site that MODIS Daily scenes are distributed at: http://ladsweb.nascom.nasa.gov/data/search.html. You should follow the same navigation and search procedures as described in that FAQ, only under Group select Atmosphere Level 2 or Level 3 Products.

What is MODIS imagery?
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.
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 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 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.
Who has the best satellite imagery?
1. Google Earth – Free access to high resolution imagery (satellite and aerial) Google Earth offers free access to some of the highest resolution satellite imagery, although the highest resolution images are actually taken from airplanes. Most of the data on Google Earth was taken in the last 3-4 years.
How does MODIS work?
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. Night time data are also available in the thermal range of the spectrum.
Where can I find the latest 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 are subsets of an image used in MODIS?
Image subsets are created for specific areas of the globe. These images are available as true color composites as well as other band visualizations and ratios which illustrate different characteristics. Historically, MODIS subset images have been customized for specific project applications or at the request of end users.
What kind of data is used in MODIS?
Provides access to a variety of direct broadcast data images including true color, SST, Chlorophyll a_2, Cholorophyll a_3, and has links to various coverage areas. The USDA Forest Service utilizes MODIS DB data to support interagency, strategic fire management.
What can MODIS imagery do for fire detection?
Access to MODIS imagery, fire detection data and other geospatial products are provided for near real-time active fire detection and monitoring covering the United States and Canada. Provides direct broadcast imagery, as well as variety of archived data images, of South and East Asia.
