Tools and Data

Tool 1

NASA Earth Observations (NEO)

http://neo.sci.gsfc.nasa.gov/

The mission of NASA Earth Observations (NEO) is to provide satellite images of Earth so that people can picture the Earth system and how it varies. Images can be selected and basic analyses performed within NEO. In addition, images can be downloaded in jpeg, png, geotiff, and Google Earth format for analysis in other applications, such as image analysis programs, GIS programs, and geovisualization programs like Google Earth. All satellite imagery is in the public domain, which means it is freely available. When using NEO images, credit NASA as the source.

Tool 2

Image Composite Explorer (ICE)

http://neo.sci.gsfc.nasa.gov/

ICE is NEO's buit-in java program for image analysis. Using pre-prepared images, ICE analyzes remotely-sensed observations of various Earth variables, provides the exact value of those variables at a given place in an image, and plots the results of analyses using a variety of graphing techniques.

Tool 3

ImageJ

http://rsb.info.nih.gov/ij/index.html

ImageJ is a public domain Java image processing program. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine. ImageJ can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF and JPEG. It can "stack" a series of images that share a single window. It can calculate area and pixel value statistics of user-defined selections. It can measure distances and angles. Images can be zoomed up to 32:1 and down to 1:32. All analysis and processing functions are available at any magnification factor. Spatial calibration can be set to provide real world dimensional measurements.

Data Source

NASA Satellite Data

Regularly updated global maps from 1985 through the present are displayed in the NEO interface.

Geospatial Coverage

Temporal Coverage

1985-2010 (present)

Dataset 1 - Aerosol Optical Thickness

The MODIS Aerosol Optical Thickness image is a product that results from a series of data processing steps undertaken by NASA scientists and technicians. The data shown in the images are monthly averages from a series of images.

Dataset 2 - Tropospheric Carbon Monoxide

This dataset comes From the MOPITT instrument and provides levels of carbon monoxide at Earth's surface in parts per billion volume (ppbv) as monthly averages.
