NDACC Data

DATA DESCRIPTION:

A full listing of the NDACC data with short descriptions is available in the Measurements and Analyses Directory.

DATA CHARTS:

Graphic displays of data availability by instrument type are available on the Instrument Tab.  An NDACC Observation Capabilities Chart is also available.

DATA TABLE:

An easy to read listing of data currently available in the database is updated twice a year.

NDACC DATA AVAILABILITY:

Public data:  All NDACC data more than two years old are public data.  Additionally some PIs have authorized their data for early release.  These data are available as soon as they are cataloged in the database.  This public record is available through anonymous ftp at ftp.cpc.ncep.noaa.gov/ndacc or by a clickable map linking sites with data directories.

Proprietary data:  All NDACC data newer than two years from acquisition and not authorized for early release are proprietary data and available only through direct accounts on the NDACC database.  Parties interested in general access to this data should prepare a proposal to the NDACC Steering Committee for consideration as NDACC collaborators.  For more information contact the NDACC Steering Committee co-Chairs:  Dr. Michael J. Kurylo or Dr. Geir O. Braathen.  Otherwise, the use of any individual NDACC data set prior to its being made publicly available (i.e., for use associated with field campaigns, satellite validation, etc.) is possible via collaborative arrangement with the appropriate PI(s).

PUBLICATION CONSIDERATIONS:

In the case of use of proprietary data that is not yet released to the general public, co-authorship shall be offered on all resulting publications to those investigators participating in the process.

It is expected that data users will consult the on line documentation and reference articles to fully understand the scope and limitations of the instruments and resulting data. Scientific users of the data are encouraged to directly contact the NDACC Principal Investigator listed in the data documentation to insure the proper use of specific datasets.

People who use NDACC data in a publication are requested to include the following acknowledgment: "The data used in this publication were obtained as part of the Network for the Detection of Atmospheric Composition Change (NDACC) and are publicly available (see http://www.ndacc.org)".

Please also send notification of publication to J. Wild so that we may add the publication to our publications list.
