You will get the most recent contact information we have. HALO-DB doesn't support a direct contact.

Only logged-in users who belong to at least one mission can create a data source (instrument or model).

As logged-in user you can subscribe a dataset.
In that case you will be informed immediately, if a new release of the dataset is available.

If you are logged-in and your account is related to dataset subscriptions, there are several ways to cancel a subscription.

• To unsubscribe datasets en bloc, please visit your personal account page.
• To unsubscribe a single dataset, please take a look on the dataset's page.
• The e-mail notification of the dataset subscription contains an encrypted link.
  Visiting that link will cancel your subscription of the dataset.
  Please don't forward the notification e-mail to third parties, as they can cancel your subscription without your affirmation.

Three pieces of information are needed for reproducibility:

• DOI of the HALO database https://doi.org/10.17616/R39Q0T;
• Dataset number;
• Release number of the dataset.

Dataset number and release are contained in the name of each downloaded file.

Yes, the HALO database fulfils all requirements. You can get DOIs for various data granularities: for a mission, for an instrument, for all versions of a data set, for a particular version of a data set, ...

Please contact HALO-DB staff to discuss the options.

However, we recommend citing the DOI of the database and specifying your dataset instead (see "How do I cite data from the HALO database?"), as this is generally the better option for reproducibility.

Yes. Additions and Corrigenda are allowed in principle and here in particular, because previous versions are kept. For reproducibility please consider "How do I cite data from the HALO database?"

Please try again later. If it still fails, please contact the site maintainers. It is a known issue that the database is prone to hanging when a large file is requested, e.g. all datasets of a campaign as a single zip file.

To establish a new mission on HALO-DB, please contact the HALO-DB staff at first.
After we have initialized a site for your mission, you may login and edit most parts of it. You can add members to your mission, assign roles to them, or revoke memberships.

Please ask any PI or Admin of that mission to sign you up. You will need to provide the e-mail address you registered at HALO-DB.

Please make sure you followed the HALO-DB specific conventions for the data format of your file. If your platform/model/instrument/ ... is not known to the HALO-DB yet, you might need to add it first. Please contact the HALO-DB staff if you need assistance with that.

Please login to HALO-DB. Mission crews are only visible for logged in users. If you do not have an account yet, please register.

Please login to HALO-DB. Additionally you might need to get signed up for the specific mission. Please contact a mission PI or Admin for that. A "download" button will show up next to the file for you then.

HALO-DB currently supports the following data formats for uploading datasets: GTE, NASA Ames, NetCDF.
These are the most common data formats used within the HALO community. Currently there are no funds available for the development of new software modules to support other formats.

Please study the log messages on the upload page. Only errors (colored red in the log) make the upload fail. Common problems include the use of characters from an extended ASCII table (e.g. "µ"), or violation of the HALO-DB conventions for your chosen data format. Eliminate the cause of the error and try again. Please contact us, if you need assistance.
