Quality Control and Global Crossover Analysis of NGDC Data

存储在国家地球物理数据中心的正在进行的地球物理数据的庞大图书馆代表了纳税人和科学家数十年和数十亿美元的集体投资。 至关重要的是，这些数据不仅要存档，而且要经过严格的质量评估和更正。 PI将为交叉误差的沿航迹和跨航迹分析开发必要的工具和程序。 PI将与数据中心及其用户合作，以确保程序得到广泛实施。 将建立一个全球重力、磁力和测深交叉误差数据库，并提供网上数据库访问。

The vast library of underway geophysical data stored at the National Geophysical Data Center represents the collective investment by taxpayers and scientists measured in decades and billions of dollars. It is vital that such data not only be archived but be subject to rigorous quality assessment and corrections. The PI will develop the necessary tools and procedures for both along-track and across-track analysis of crossover errors. The PI will collaborate with the Data Center and its users to ensure the procedures are broadly implemented. A global database of gravity, magnetics and bathymetry crossover errors will be assembled and web-based access to the database will be provided.
