NASA ARSET maintains an up-to-date listing of the many webtools available for satellite data access, processing, and visualization. Here, we list a few of them. For the novice, Worldview is a powerful and rather user-friendly webtool for data visualization.

There are number of tutorials on accessing, processing and visualizing satellite data. For example,

Data discovery, visualization, and analysis resources for the end-user.

True color imagery and Smoke  
Application Specific  
EOSDIS Earth Observing System Data and Information System.  Useful web tools are available to search data files by instrument and pollutant type.
Land Atmosphere Near-real-time Capability for EOS is NASA’s main tool for visualization and download of near-real-time data and imagery.
Earthdata Search Search, access and download data files, with spatial and temporal sub-setting.
