The JPSS Proving Ground and Risk Reduction program’s primary objective is to maximize the benefits and performance of NPP/JPSS data, algorithms, and products for downstream operational and research users (gateways to the public) through:
• Detailed characterization of data attributes such as uncertainty (accuracy and precision) and long-term stability
• Engaging users to enhance their applications (and develop new ones) by working together to facilitate optimal utilization of JPSS data, algorithms and products in combination with other data sources through onsite/offsite testbeds, experimental data streams, and intercomparisons of enhancements with baselines
• Education, Training and Outreach
• Facilitating transition of improvements (new algorithms/applications) to operations.
Proving Ground & Risk Reduction for JPSS

Call for proposals due Jan 20, 2012
Introduction Identify and describe end user application(s) and importance, and the benefit JPSS data can provide
Identify and describe any current limitation(s), requiring additional research and/or feedback to further realize this benefit.
Identify a user that will be engaged, and describe how you will engage the user, regularly, to understand JPSS products, provide test datasets and to obtain feedback.
Proposed Work and Technical Approach Describe methodology to use JPSS data (and other data sources, if necessary) to improve the identified user application.
