2012 NDACC News and Highlights

January 2012/May 2012:

This section highlights significant items of interest within NDACC, with updates at least annually following the NDACC Steering Committee meeting.

NORS and rapid data delivery to the NDACC database

The Demonstration Network Of ground-based Remote Sensing observations (NORS) is a new EU Framework 7 R&D project in support of the GMES Atmospheric Service (GAS) that began on November 1, 2011 and will run for 33 months.

The project is built around 4 NDACC pilot stations (Ny Alesund, the Alps: (Bern, Jungfraujoch, and Observatoire de Haute Provence), Izana, and Reunion Island) and 4 NDACC remote sensing techniques for studying atmospheric composition (microwave, differential lidar, and infrared, and UV/Visible differential optical absorption spectrometry). NORS focuses on a limited number of target species in the troposphere and the stratosphere: Ozone, CO, CH4, NO2, HCHO and aerosol extinction. The general objective of the project is to perform the required research and development necessary to optimize NDACC data products to support quality assessments of the future GAS.

One of the more specific objectives is to achieve data submission to the NDACC database with a maximum delay of 1 month from data acquisition, in the GEOMS HDF file format, one of the standard data file formats in the NDACC database.

If these rapid delivery data are of less quality than the standard verified NDACC data or if the data file is less complete (e.g., missing uncertainty estimates), then the data must be identified as 'RD' in the DATA_QUALITY attribute of the data file; the data provider will submit a standard verified version of the same data later on.

The 'RD'-data will show up in the newly created RD directory on the NDACC ftp public data server and will be removed by the data provider as soon as the standard verified data become available. The latter will appear on the NDACC public database ftp server as usual in the corresponding station directories.

The existence of the RD directory is a new feature of the NDACC database that has been implemented for the purpose of NORS but that is available to all NDACC PIs who want to use this option. The purposes of the RD directory are (1) to enable the data providers to rapidly submit data that are suitable for or first-look purposes - but that may require a further quality-control before being submitted to the regular station data, and (2), to make the quality distinction clearly visible to the users of the data. Further inquiries on the use of this option should be directed to the NDACC Database Administrator.

NDACC Steering Committee Meeting 2012

The NDACC 2012 Steering Committee Meeting will be held in Garmisch, Germany October 14-19 and will include 3 days of business, and visits to the NDACC Measurement Sites at Zugspitze and Hohenpeissenberg.  For additional infomration please contact the NDACC Co-chairs: G. Braathen or I.S. McDermid.

TCCON

The NDACC welcomes as a Cooperating Network the Total Column Carbon Observing Network (TCCON). Though the primary data product is high precision total column CO2 several other gases are retrieved and archived as well. Sites for the network span the globe to provide diverse and targeted data for use as validation sites for the GOSAT and OCO-2 CO2 observing satellites as well as monitoring the seasonal cycle and long-term evolution of CO2. The network shares common methodologies, technical issues and membership with the NDACC/IRWG. The instruments are solar viewing Fourier transform spectrometers providing near-infrared spectra. Employing a network wide common retrieval technique and site specific aircraft calibrated retrievals the network aims to provide a temporally dense, globally consistent data coverage. Details and data can be found at http://www.tccon.caltech.edu/ .

2012 Call for International Teams in Space Science

The International Space Science Institute (ISSI) as issued its 2012 call for Team proposals. Details can be found at the ISSI web site: http://www.issibern.ch/spotlight/ISSI_annual_call2012.pdf

The 2011 NDACC Symposium

An international Symposium celebrating 20 years of global atmospheric research enhanced by NDACC/ NDSC observations was held the November 7-10, 2011 in Saint Paul, Reunion Island, France. The symposium was organized by the Observatoire de Physique de l'Atmosphere de la Reunion. Attendees were given the opportunity to visit the Maido Observatory which is scheduled to begin operations in early 2012. A Symposium summary is being written and will be available shortly.
