SPAce Readiness Coherent Lidar Experiment A Cancelled New Millennium Program mission formerly being developed at the NASA Marshall Space Flight Center to test the measurement of winds using lidar (laser radar) from the Space Shuttle. "Direct tropospheric wind measurements would provide a greater impact on numerical weather prediction models than any other new space-based observation." National Polar-orbiting Operational Environmental Satellite System (NPOESS) Integrated Program Office (IPO), 28 June 1996.
