ITOP Data Submission Instructions

A ITOP Data Management World Wide Web (WWW) page has been created and is accessible from the ITOP home page. This page contains relevant links to project and data documentation, distributed data access, and other collaborating projects data sets.

An initial master list of all ITOP international data sets (with links) will be compiled to provide easy access to all ITOP data sets (both operational and research). Data sets are grouped by categories and sorted by data type. This list will be updated frequently. It is linked from the ITOP data management WWW page or directly at: .

If you collected data for ITOP, 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 loehrer at If you already have your data sets available on-line, please provide the WWW link or FTP access information. Once your data set (with meta data) is available, a link will be provided from the master list WWW 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 U.S. ITOP Long-term Data Archive at NCAR/Earth Observing Laboratory (EOL). Data set (and metadata) documentation guidelines are available here.

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

  • FTP:
    LOGIN: anonymous    (No password required.)
    cd /pub/data/incoming/itop   (NOTE: This command should be done all in one step.)

It is very important to send an e-mail to loehrer at, 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. data formats, descriptions, acknowledgments, and metadata). Documentation files may be e-mailed to loehrer at directly if preferred. If password protection is required for these data, please indicate this at the time of submission. You will receive a unique "user ID" and "password" that can be changed at any time upon request. 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 NCAR/EOL shipping address below.

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