AbstractEffective use of satellite data for environmental monitoring requires consistent, high-throughput processing of large volume of data as they are transformed from raw measurements to useful higher level products. GeoComp-n was developed as a software solution to this challenge, for use with satellites that provide daily data for the landmass of Canada or comparably large areas. In this second paper, we discuss the characteristics of algorithms and methods used in the generation of GeoComp-n products. The theoretical basis and assumptions in the algorithms are described, and the quality of the products is discussed based on validation studies. Examples of a suite of products for Canada during one 10-day period illustrate the diversity and quality of observations for the terrestrial biosphere that may be derived from satellites, frequently and over large areas. Issues related to quality assessment in a production environment are also discussed.
