0447343AgnewThis grant supports the cost of replacing failed and antiquated air conditioning equipment that is essential for the continuous operation of two long baseline interferometric laser strainmeters in southern California that have been collecting near-continuous strain records for over 20 years, in the case of the Pinon Flats Observatory (PFO), and over 10 years, in the case of the Durmid Hill (DH) instrument. These instruments provide unique and highly sensitive information on short-period transient and secular strain rates proximal to the active transform system of the North American-Pacific plate boundary. In addition, continued operation of these instruments will complement a planned continuous GPS and borehole strainmeter network of instruments that is now under construction along the west coast of the north American continent (the Plate Boundary Observatory (PBO) component of EarthScope). ***

0447343 Agnew该补助金支持更换故障和陈旧的空调设备的费用，这是必不可少的两个长基线干涉激光应变仪在南加州，已收集近连续应变记录超过20年，在Pinon Flats天文台（PFO）的情况下，超过10年，在杜米德山（DH）仪器的情况下连续运行。 这些仪器提供了关于北美-太平洋板块边界活动转换系统附近的短周期瞬态和长期应变率的独特和高度敏感的信息。 此外，这些仪器的继续运行将补充一个计划中的全球定位系统和钻孔应变仪仪器连续网络，该网络目前正在沿着北美大陆西海岸建设（EarthScope的板块边界观测站组成部分）。 ***
