PECAN Data Submission Instructions

The PECAN home page contains relevant links to project and data documentation, distributed data access, and other collaborating projects' data sets.

An initial master list of all PECAN international data sets (with links) has been compiled to provide easy access to all PECAN 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. It is available directly at PECAN Master List.

If you collected data for PECAN, please review this list to verify that your data set(s) are properly named with the appropriate Principal Investigators (PIs) identified. Please e-mail any corrections, additions, or deletions directly to Scot Loehrer. If you already have your data sets available on-line, please provide the web link or FTP access information. Once your data set (with metadata) is available, a link will be provided from the master list web page along with a submission date to track future data set upgrades or revisions (if needed).

Please submit your data set(s) (including accompanying metadata or documentation files) to the PECAN Long-term Data Archive at NCAR Earth Observing Laboratory. Data set (and metadata) documentation guidelines are available by direct link at: PECAN Data Set Documentation ("Readme") Guidelines.

To expedite matters, the EOL has established an anonymous FTP capability to accept your PECAN data set(s). The Internet address is:

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

It is very important to send an e-mail to loehrer at ucar.edu indicating that the data file(s) have been FTPed, along with the file(s) names, data contact information, any data restrictions, and appropriate file documentation (i.e., authorship information including corresponding author(s), data formats, descriptions, acknowledgments, and metadata). Documentation files may be e-mailed to loehrer at 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 Scot Loehrer 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 PECAN archive. Feel free to contact me should you encounter any problems or have any questions.
