The purpose of this website is to provide information about the Dark Target aerosol retrieval algorithm and products. We provide information and content for those new to remote sensing as well as more experienced users.  If you are new to remote sensing we suggest you start by reading the content in the "Aerosols Overview" section.  This section begins with some general background on the remote sensing of aerosols, followed by general information about "Dark Target" retrievals and then begins to describe in some detail the dark target retrieval algorithm.
