Step 6, After 60 days of data submission, Sadr administrator will publish the approved data online. If users or journals have special requirements, the publishing time will be decided by users or journals.
A: The data came from various research fields. The basic requirements are as follows:
(1) Supports most types of files (such as text, spreadsheet, video, images, software code), includes multiple file archive.
(2) Data size is unlimited. If you need to upload files larger than 10G at once, you need to charge a certain extra fee. See the charging standard for details.
(3) Due to the openness of NSSDC SADR data, data containing personal privacy information cannot be accepted. Please finish the relevant anonymous processing before uploading the data.
(4) For confidential data, please contact the center first. For contact information, see Contact us
(5) The data that reject CC0 or CC-BY 4.0 license cannot be accepted and published.
A: As a multidisciplinary repository NSSDC SADR does not limit the format and the subject of the data submitted by the user. Considering the reusability and long-term access of the data NSSDC SADR recommends that your data files be stored in the preferred format in the following table. In addition, NSSDC SADR provides other recommended formats for data files. Data files in this format are also highly accessible and robust, can be used as a secondary alternative to data organization and storage formats.
If your data file format is not already on the recommended list below, we recommend that you evaluate the long-term sustainability and accessibility of your submitted data file in the following ways:
(1) The file format you are using is a common format in the domain;
(2) The file format you are using has an open specification or standard;
(3) The file format you are using is independent of a particular software, developer or vendor.
If you cannot meet the above requirements, please do your best to meet them.
A: When storing data, we assign a dataset digital object identifier(DOI) to your data, by listing sources and DOI references in the paper.

A:(1) Basic data check. Such as can the file be opened; whether the uploaded file contains virus; confirm that there are no copyright restrictions; whether contains sensitive data.
(2) Verify the integrity and correctness of the metadata. Such as check publishing information, keywords, subject classification, etc.
(3) Assign and register unique identifiers for datasets. NSSDC SADR adopts a pattern of double identification for each dataset, assigning DOI and PID to each submitted dataset.
(4) Long-term preservation and available download. The data can be accessed through related publications or discovered through retrieval services.
A: NSSDC SADR provides statistics on the number of times each dataset is accessed, downloaded and referenced, and supports chart viewing. This also includes relevant statistics of the data accessed from the cooperative journals. But NSSDC SADR does not track or provide specific information about the users who downloaded it.
