DC3 Data Submission Instructions (Non-Aircraft)

The DC3 Data Archive contains a master list of all DC3 international data sets (with links) and has been compiled to provide easy access to all DC3 data sets (both operational and research). Data sets are grouped by platform and sorted by data type (i.e., aerosol, cloud properties, radar, satellite, etc.). This list will be updated frequently and is linked in the Data Access section of the DC3 Project Page. It is available directly at DC3 Data Archive. Please e-mail all corrections, additions, or deletions to the DC3 Data Archive list directly to eol-archive@ucar.edu.

If you already have your data sets available on-line, please provide the web link or FTP access information to NCAR Earth Observing Laboratory (EOL). Once your data set (with metadata) is available, a link will be provided from the DC3 Data Archive along with a submission date to track future data set upgrades or revisions (if needed).

Please submit both your data set(s) and accompanying metadata or documentation files to the DC3 Data Archive. Data set documentation guidelines are available by direct link here.  NCAR EOL has established an anonymous FTP to accept your DC3 data set(s).  To FTP data to the NCAR EOL DC3 anonymous FTP, please use the following instructions:

  • FTP:    ftp.eol.ucar.edu
    Login:   anonymous    (No password required.)
    cd /pub/data/incoming/dc3  (NOTE: This command should be done all in one step.)

Once you have FTPed your data set to NCAR EOL, it is very important to send an e-mail to eol-archive@ucar.edu with information about the data file(s) that have been FTPed including file names, authorship information including corresponding author(s), data restrictions, and file documentation (i.e., data formats, descriptions, acknowledgments, and metadata). Documentation files may be e-mailed to eol-archive@ucar.edu directly if preferred.

Password protection is available for this data set upon request.  The data set will not be password protected unless requested at the time of submission.  If password protection is requested, you will receive a project-specific "user ID" and "password." If you require additional security, please contact eol-archive@ucar.edu to request a unique "user ID" and "password" for your data. For users without direct Internet access, or if your data set(s) are too large to FTP, you may send digital file(s) on magnetic or optical media (with documentation) by conventional mail to the EOL shipping address below.

Thank you very much for your assistance in providing final data to the DC3 archive. Feel free to contact us should you encounter any problems or have any questions.
