This paper informs scientists, system developers and managers of science data about the current acquisition, processing and distribution of MODIS data at the NASA GES DAAC. In addition, this paper presents the Simple, Scalable, Script-based Science Processor (S4P), a data-driven processing system. This paper also discusses data product sizes and daily volumes, different mechanisms for ordering the data, data distribution policies and data subscription services. In particular, this paper describes a search and order Web interface developed at the GES DAAC that provides users with an efficient gateway to MODIS and other remote sensing data.
