Description—How to search

Welcome to the Data Detective,
the comprehensive search tool of HALO-DB.
The following specifications were made, to give you a understanding of the capacious search criteria to get datasets where you are focused on.

  • There are no mandatory fields. If no specifications are selected, you will get all datasets.
  • The different search criteria are connected via a logical AND.
  • Exception: Inside the search criterion mission (multiple inputs are possible), the selected inputs are connected via a logical OR.

Search Criteria

  • Text: free text in the dataset's metadata: comment, name of the parameter or variable
  • Missions: You can specify the datasets of the missions you are interested in.
  • Measurement Period: You can specify a start or/and a stop date. In general datasets or datasets of a mission, which are associated with these period will match the query.
