The CHAMP data base on this server has the following basic directory structure:

/Product Section/Level/Product/Year

Product Sections:

  • AI  = Atmosphere/Ionosophere
  • ME = Magnetic/Electric Field
  • OG = Orbit & Gravity Field related product
  • GPS = Data from the former CHAMP related highrate GPS ground station network (will be released here soon!)

For the sections AI, ME and OG all data products are stored in daily files, given as zip-, cdf- or tar-files


DOI-referenced citable CHAMP data products can also be found in the data portal of GFZ Data Services.
