We propose to perform an Effelsberg HI survey which covers the whole northern sky north of Dec = 0° on a fully sampled grid. Using two different spectrometer backends, we perform for the first time a galactic and extragalactic survey in parallel. Towards the Sloan Digital Sky Survey area the survey is optimized to reach its highest sensitivity of 2 mJy/b.a.; this corresponds to a mass sensitivity of 1.8-107 Msun at the distance of the Virgo cluster. The Milky Way survey will have a sufficient overlap with the northern extension of the Parkes GASS survey but will have much higher sensitivity. Accordingly, the Effelsberg and GASS survey combined will be the data resource for multi-frequency astronomy until the era of the Square Kilometer Array. The Effelsberg HI survey is a joint project between the Argelander-lnstitut für Astronomie (AlfA) and the Max-Planck-lnstitut für Radioastronomie (MPIfR). The project is located at AlfA, while the MPIfR provides the access to the instrument.

我们建议进行一次Effelsberg HI巡天，它覆盖了Dec = 0°以北的整个北方天空。使用两个不同的光谱仪后端，我们第一次并行执行银河系和河外的调查。在斯隆数字巡天区，对巡天进行优化，使其达到最高灵敏度2 mJy/b. a;这相当于室女座星系团距离上的质量灵敏度为1.8-107 Msun。银河系巡天将与帕克斯GASS巡天的北方延伸部分有足够的重叠，但灵敏度要高得多。因此，Effelsberg和GASS调查相结合将成为多频天文学的数据资源，直到平方公里阵列时代。Effelsberg HI巡天是Argelander-Institut für Astronomie（AlfA）和Max-Planck-Institut für Radioastronomie（MPIfR）的联合项目。该项目位于AlfA，而MPIfR提供了对仪器的访问。
