MRI-R2: Acquisition of GPS Equipment for Africa Array

0960160米勒该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。这项主要研究仪器回收和再投资（MRI-R2）计划拨款支持采购20个双频GPS接收器和自动气象站（Met站），用于测量风速和风向、液体降水、气压、温度和相对湿度。新的GPS/met站将由美国非营利性公司UNAVCO的员工在非洲大陆的选定地点安装，其中15个将与现有的地震记录仪一起安装，这些记录仪是以前美国国家科学基金会资助的非洲大陆地震网络的一部分（AfricaArray; EAR - 0446647）。所有全球定位系统和气象数据最终将在联安援助团数据管理系统内存档，并通过网络公开分发。运营和管理责任和成本将分配给东道国的AfricaArray台站运营商，以及地球科学委员会（南非）、威特沃特斯兰德大学（南非）和宾夕法尼亚州立大学，遵循目前用于运营和维护AfricaArray地震台站的模式。非洲阵列大地测量网将为构造学研究提供前所未有的非洲大陆地壳变形观测，特别是对了解东非大陆裂谷盆地的结构、力学特性和演化的研究。气象观测将极大地扩展目前整个非洲大陆的环境观测能力，并将支持气候和水文模型。这些项目将通过现有的大学与非洲教育机构的合作，以及为美国学生提供在非洲从事研究工作的机会，让代表性不足的群体参与进来。“非洲阵列”的一个更广泛的目标是将培训和研究项目结合起来，为非洲建立和维持一支地球科学人才队伍

0960160MillerThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Major Research Instrumentation Recovery and Reinvestment (MRI-R2) Program grant supports acquisition of 20 dual-frequency GPS receivers and automatic weather stations (Met stations) that measure wind speed and direction, liquid precipitation, barometric pressure, temperature, and relative humidity. The new GPS/met stations will be installed by employees of the U.S. non-profit corporation UNAVCO, Inc. at selected sites across the African continent, with 15 to be collocated with existing seismic recorders that are a part of a previously NSF-funded seismic network on the African continent (AfricaArray; EAR - 0446647). All GPS and met data will ultimately be archived within the UNAVCO data management system and openly distributed via the Web. Operations and management responsibilities and costs will be distributed amongst AfricaArray station operators in host countries, plus the Council for Geoscience (South Africa), The University of the Witwatersrand (South Africa) and Penn State, following the model currently used to operate and maintain AfricaArray seismic stations. The AfricaArray geodetic network will enable unprecedented observations of African continent crustal deformation for research in tectonics with a particular interest in understanding the structure and mechanical properties and evolution of the continental rift basin in East Africa. Meteorological observations will dramatically expand current environmental observational capabilities across the continent and would support climatological and hydrological models. The PIs will engage underrepresented groups through existing university collaborations with African educational institutions and through opportunities for U.S. students at minority-serving institutions opportunities to do research in Africa. A broader goal of AfricaArray has been to couple training and research programs for building and maintaining a geoscientific workforce for Africa.***
