Lowell GIRO Data Center (LGDC)


for DIDBase and DriftBase repositories

Release date: September 11, 2013

Last updated: May 5, 2014


Heavy investments of time, effort, expertise, and funds continue to be made to produce, collect, quality control, interpret, and archive ionosonde data. It is therefore important that the data providers and LGDC are appropriately acknowledged in scientific publications that include analysis of data obtained from LGDC servers.  

Roles and Responsibilities

  1. Lowell GIRO Data Center (LGDC) is a Data Sharing Infrastructure. Data providers contribute the ionogram and drift data to LGDC and in return gain free access to data from all the other GIRO participants.
  2. LGDC data records are owned by the original data providers (i.e., observatories that operate the instruments).
  3. On behalf of the data owners, LGDC takes responsibility for
  4. To facilitate convenient access and use of LGDC data collections, LDGC takes responsibility for

LGDC Account

To register for read-only Lowell DIDBase or DriftBase accounts, send request to Prof. Bodo Reinisch, Bodo_Reinisch@uml.edu.

A username and password will be issued by the LGDC Account Maintenance team for SAO Explorer connection to Lowell DIDBase and Drift Explorer connection to Lowell DriftBase. The read-only account can be shared within the organization that applied for access.

Rules of the Road

The GIRO concept of data access has always been "free data to scientists" without regard to institutional, geographic, and national borders.
  1. Free online access to acquired data is arranged only for educational and non-commercial research purposes.
  2. Data users are strongly encouraged to contact designated persons at the data supplier organization prior to using the data to discuss the intended usage in the light of possible data issues. For contact person information for each Digisonde observatory, please refer to the Acknowledgements List and Digisonde Station List.
  3. Should a scientific publication evolve from the conducted analysis of data from LGDC or its mirror servers, the authors are requested to:

  4. Data obtained from the LGDC are to be shared only with users who have an up-to-date LGDC account.
  5. If autoscaled records are edited in the process of analysis, we strongly encourage sharing of the edited data with the DIDBase community.
