Top News:

06 July 2004:
  • SCIAMACHY back to measurement
    Shortly after yesterday's CCA MCMD check error, recovery back to measurement was initiated. The transfer to HEATER mode started at 13:25 UTC and today in orbit 12286 (July 6th, 10:22 UTC) the MPS schedule was resumed. We expect that detectors 1-6 will reach stable temperatures tomorrow, July 7th, at about 13:30 UTC. Detectors 7 & 8 require about 16 hours more time to stabilize.

05 July 2004:
  • Transfer to R/W WAIT mode
    In orbit 12269, (July 5th, 05:52 UTC), a CCA MCMD check error has occurred and has sent us to R/W WAIT. SCIAMACHY had the last error of this kind 6 months ago in January 2004, i.e. the frequency is compliant with the estimate of 2-3/year.

    Hopefully SCIAMACHY is running in normal mode by tomorrow.

  • HCHO has been added to the NRT trace gases

Top Introduction:

The ICARTT (International Consortium of Atmospheric Research on Transport and Transformation) is combining several regional research projects, independently developed by different international groups in the US and in Europe, to develop a better understanding of the evolution of anthropogenic emission injected into the atmosphere. The major participants of the consortium are NOAA with the New England Air Quality Study - Intercontinental Transport and Chemical Transformation (NEAQS - ITCT 2004) program, NASA with the Intercontinental Chemical Transport Experiment - North America (INTEX-NA) earth science mission and on the european side the Intercontinental Transport of Ozone and Precursors - North Atlantic Study (ITOP).

The regional projects are involving several aircraft missions in the area of the NE-US, the North Atlantic and Western Europe to study local air quality. Joining the efforts by coordinating the single missions, will provide information about the pathways of intercontinental transport of pollution and about the chemical transformation, the aging of the air masses, as they pass from the US over the Atlantic to Europe.

Therefore three main objectives are:

  • to study the regional air quality to constrain the emission source strength and the regional pathways of pollution in the northeastern United States and the Maritime Provinces of Canada.
  • to investigate major intercontinental transport events, which are connected to uplifting of pollution near the source region due to the warm conveyor belt. But also investigation of boundary layer outflow mechanisms.
  • a detailed analysis of the radition balance, in particular to measure separately the direct and indirect radiative effects of aerosol pollution in plumes.

In support of ICARTT, the Institute of Environmental Physics at the University of Bremen with support from NOAA and NASA is providing near real time images of tropospheric NO2 from SCIAMACHY and GOME measurements. The plots are meant as quick look analysis and numbers will change in post campaign analysis.

Currently, only NO2 data is available, but more trace species will be added soon.

More details on the analysis procedures can be found in the references given below.

Top Data:

The data products for the ICARTT campaign, currently NO2 and H2O, are directly accessible via the calendar below. These plots are produced automatically and are based on SCIAMACHY raw data. Usually, plots should be available with a delay of one day. If you experience any problems, please contact Andreas Heckel.

In addition all currently processed data products from SCIAMACHY can be found in the SCIAMACHY Data Archive of IUP / ife Bremen.
