! The PSNC LTA site is undertaking a major upgrade that is to result in significant improvement of performance and stability. While this activity is underway, the current deployment will be kept operational but users that are experiencing siginificant issues with retrieving data from the Poznan facility are, besides reporting these issues as usual, advised to consider postponing data access from Poznan until the upgrade is finished. The timescale is not yet completely fixed but anticipated to conclude around May 2024. !
! The FZJ LTA site will be out for maintenance on Wednesday April 17th, starting at 9:00 CEST and planned to finish at 14:00 CEST. During maintenance, it will not be possible to retrieve data that is stored on the Juelich facility. !
Welcome to the LOFAR Long Term Archive (LTA) web service
This service is the main access point for searching and downloading data from the LOFAR LTA. Please visit the documentation
for a description on how to use this service.
From March 1 2015 onwards, cycle data which have passed the proprietary period will be publicly available.
All metadata in the Archive can be queried anonymously at anytime, but downloading public data can only be done
by registered users (follow the "Create account" link on the LTA login page). Non-public data can only be downloaded by project members.
Note: for the first cycles of LOFAR operations, part of the data were ingested in the archive without metadata.
These data cannot be found using the standard search parameters, except for the appropriate Observation ID.
When unspecified data are present in a project, this is listed in the "Unspecified" column on the Projects page.
Data can still be requested using the "Project" pulldown in the various Search options.
A list of all LOFAR observing cycles and approved projects can be found here.
For more information on this web service see the Lofar wiki.

by Samenwerkingsverband Noord-Nederland (SNN) and the Groningen Municipality. The
project was financially supported by the European Fund for Regional Development
and the Dutch Ministry of Economic Affairs, Agriculture and Innovation (Pieken in de Delta),
the Province of Groningen and the Province of Drenthe.
This infrastructure is part of a project that has received funding from the European Union's Horizon 2020
