NDACC Sites and Intro

This Directory summarizes the operational status of the Network for the Detection of Atmospheric Composition Change (NDACC). Long-term NDACC measurement activities (both “active” and “inactive”) are listed in Sections Ia and Ib. Sections IIa and IIb include NDACC measurement activities conducted intermittently or during limited duration campaigns. Some of the locations listed in Section II appear in Section I as well since they are also associated with long-term data sets.

Shading throughout this report indicates stations or instruments that are currently considered to be “inactive”. This designation is assigned

  • when there has been a permanent cessation of measurements or
  • when the measurement PI is no longer considered to be active in the NDACC due to the cessation of data archiving at the NDACC Data Host Facility and of communications with the NDACC Steering Committee.

A fundamental aim of the NDACC is to provide high-quality data suitable for scientific studies of the stratosphere and upper troposphere. The NDACC Theory and Analysis Working Group promotes the use of the NDACC data by all interested researchers. All NDACC data over one year old is publicly available. However, many NDACC investigators have agreed to make their data publicly available immediately upon archiving. The public record is available through anonymous ftp at ftp.cpc.ncep.noaa.gov/ndacc/station.

The use of NDACC data prior to its being made publicly available (i.e., for field campaigns, satellite validation, etc.) is possible via collaborative arrangement with the appropriate Principal Investigator(s). Rapid delivery data, which will likely be revised before entry in the full database, is also available for some instruments at ftp://ftp.cpc.ncep.noaa.gov/ndacc/RD.

In all cases when NDACC data is used in a publication the authors agree to acknowledge both the NDACC data center and the data provider. Whenever substantial use is made of NDACC data in a publication an offer of co-authorship will be made through personal contact with the data providers or owners.

Users of NDACC data are expected to consult the on-line documentation and reference articles to fully understand the scope and limitations of the instruments and resulting data and are encouraged to contact the appropriate NDACC PI (listed in the data documentation on the web page) to ensure the proper use of specific data sets. Those using NDACC data in a talk or paper are asked to acknowledge its use, and to inform the Theory and Analysis Working Group PIs of any relevant publications.

NDACC Long-Term Measurement Stations

This listing includes all stations for which long-term data sets exist in the NDACC archive. Numbers in brackets, [], appearing after a station indicate the NDACC Cooperating Network that also makes measurements at the station (see Section III): 1 = AERONET, 2 = AGAGE, 3 = BSRN, 4 = GRUAN, 5 = MPLNET, 6 = NOAA/HATS, 7 = SHADOZ, 8 = TCCON.
