Description and Objectives

• Deliver an end-to-end simulator to quantitatively assess the scientific value of a fully functional, model-driven sensor web. The overall goal is to provide an objective analysis tool for Decadal Survey mission planning. The tool would enable systems engineers and Earth scientists to define and model candidate mission designs and operations concepts and accurately assess their impacts.

Technical Approach

• Build on prior Sensor Web Simulator (SWS) work.
• Focus on meteorological applications where information derived from a numerical model is used to intelligently drive data collection for operational weather forecasting.
• Simulation is essential - development costs and deployment risk of an operational sensor web system are very high. The goal is to:
  • identify types and quantities of sensor assets and their interactions;
  • evaluate alternative observing system implementations;
  • quantify potential development costs;
  • reduce operational deployment risk

Main Innovation(s)

• Unique capability that does not exist elsewhere; model and quantify potential benefits to numerical forecast model driven sensor web ops concepts.

Infusion Potential

• Integrated Design mission engineering and instrument design studies: Mission Design Lab, MDL, and Instrument Design Lab, IDL, as well as new Architecture Design Lab (ADL) studies.
• Future Earth Science Decadal Survey Missions, such as XOVWM, GWOS, GOES-R, PATH.
