The Combined Array for Research in Millimeter Astronomy (CARMA) was formed from the merger of three telescope arrays supported by the Division of Astronomical Science's University Radio Observatories (URO) Program: Caltech's Owens Valley Radio Observatory (OVRO) array of six 10.4-meter-diameter telescopes, the Berkeley Illinois Maryland Association (BIMA) array of nine 6.1-meter-diameter telescopes, and the University of Chicago's Sunyaev-Zeldovitch Array of eight 3.5-meter-diameter telescopes. CARMA currently achieves resolutions as high as 0.2 arcseconds at a wavelength of 1mm and, due to its heterogeneous combination of telescope diameters, provides excellent imaging over a wide range of angular scales. Science enabled by CARMA covers a broad range of astronomical topics, including star formation and molecular clouds, studies of external galaxies, and the investigation of solar system objects. CARMA is a pathfinder for the Atacama Large Millimeter Array (ALMA) and a pipeline for training experts in the field of millimeter interferometry to take full advantage of ALMA's capabilities for US astronomy. Users outside the CARMA collaboration receive 30% of all observing time.

毫米波天文学研究组合阵列（CARMA）由天文科学部大学射电天文台（URO）计划支持的三个望远镜阵列合并而成：加州理工学院的欧文斯谷射电天文台（OVRO）阵列的6个10.4米直径的望远镜，伯克利伊利诺伊州马里兰州协会（比马）阵列的9个6.1米直径的望远镜，以及芝加哥大学的Sunyaev-Zeldovitch阵列的8个3.5米直径的望远镜。CARMA目前在1毫米波长下的分辨率高达0.2角秒，并且由于其望远镜直径的异质组合，可以在很宽的角度范围内提供出色的成像。 CARMA所支持的科学涵盖了广泛的天文学主题，包括星星形成和分子云，外部星系的研究以及太阳系天体的调查。CARMA是阿塔卡马大型毫米波阵列（阿尔马）的探路者，也是培训毫米波干涉测量领域专家的管道，以充分利用阿尔马的能力为美国天文学服务。 CARMA合作之外的用户获得所有观察时间的30%。
