Data Use Policy

Data from the Megacities Carbon Project in Los Angeles are made freely available to the public and the scientific community in the belief that their wide dissemination will lead to greater understanding and new scientific and policy insights. The availability of these data does not constitute publication of the data or permission to use the data, or information contained in it, for publication or any commercial use.

Every effort is made to produce the most accurate and precise measurements possible at the time of their acquisition. However, we reserve the right to make corrections to the data based on scientific grounds, e.g., recalibration of standard gases or discovery of operational issues not known at the time of the release.
If the data are obtained for potential use in a publication or presentation, the Megacities Carbon Project personnel should be informed at the outset of the nature of this work.

If the Megacities Carbon Project data are essential to the work, or if an important result or conclusion depends on the data, it may be appropriate for those obtaining the data to consider co-authorship. It is strongly encouraged that topics be discussed at an early stage in the work. Manuscripts using the data should be sent to the Megacities Carbon Project team for review before they are submitted for publication to insure that the quality and limitations of the data are accurately represented.

Sharing of these manuscripts will result in a prompt response from project participants.
To discuss publication, presentation and collaboration, please contact the Megacities Carbon Project describing your plans for use.

Reciprocity Agreement

Use of these data implies an agreement to reciprocate, particularly in the case of scientific research efforts where data sharing has the potential to advance the scientific understanding of the systems and or processes involved. Organizations making similar measurements agree to make their best efforts in making their own data available to the general public and to the scientific community in an equally complete and easily accessible form. Modelers are encouraged to make available to the community, upon request, their own tools used in the interpretation of the Megacities project data, namely well documented model code, transport fields, and additional information necessary for other scientists to repeat the work and to run modified versions. Model availability includes collaborative support for new users of the models.

Availability

The Megacities monitoring network is currently undergoing commissioning. Data quality-control review, calibration and error flagging efforts are being completed at roughly 6 month intervals. The resulting data files will be posted here with 1-3 month latencies. The first data release is scheduled for June 2016
