Pinyon Flat Observatory: A Facility for Studies of Crustal Deformation

该合同为位于南加州的平台天文台（PFO）的运行和维护提供部分支持。PFO由加州大学圣地亚哥分校的工作人员操作，目的是开发、测试和校准测量长期地壳变形和地震活动的仪器。该设施被来自美国和国际学术研究机构的众多研究人员以及来自美国地质调查局、国家航空航天局和国家大地测量局（NOAA）等几个美国联邦机构的调查人员使用。

This award provides partial support for the operation and maintenance of Pynion Flat Observatory (PFO) in southern California. PFO is operated by staff at the University of California at San Diego for the purpose of developing, testing, and calibrating instruments for measuring long-term crustal deformation and seismic activity. The facility is used by numerous researchers from various U.S. and international academic research institutions as well as by investigators from several U.S. federal agencies such as the U.S. Geological Survey, the National Aeronautics and Space Agency, and the National Geodetic Survey (NOAA).
