Abstract: EarthScope will produce a volume of raw data that is unprecedented in 
the Geosciences. Transformation of that raw data into useable forms 
(ÒproductsÓ) that are of interest to various communities, ranging from research 
scientists to K-16 teachers, in a consistent, timely, fashion is a major 
challenge. Integration of these products across the spectrum of subdisciplines 
contributing to the EarthScope effort as well as integration with the existing 
observational data is an equally daunting challenge. We are developing an 
automated processing framework for use in preparing USArray products. As a 
prototype, we use standardized ÒReceiver Reference ModelsÓ (RRM), an approach 
analogous to Centroid Moment Tensors (CMT). The RRM will serve as a means of 
quickly identifying anomalous regions; as a starting point for more detailed 
analysis of USArray data, such as more rigorous imaging methods; and as an 
easily-accessible resource for other research geosciences who need to correlate 
their results with seismologically-determined earth structure. One major 
ÒcustomerÓ for EarthScope products will be the K-16 education community. The 
RRM project is developing a searchable database of crustal thickness and other 
bulk properties accessible via a web browser. Students and teachers interested 
in learning more about variations in earth structure in a specific region would 
be able to easily produce a map from this interface using commonly-known 
parameters such as zip code or city/state name. This would provide a link into 
the classroom for EarthScope results.
