developments 1
Developments (1)
  • PI left TNO DSS per 1 January 2007 for FMI/UHEL
  • Agreement between TNO and FMI:
    • FMI takes over the responsibility for delivering a demonstration product
    • TNO trains 2 people from Helsinki to use the AATSR aerosol retrieval algorithms (Jan 2007)
    • TNO provides source codes and support
  • AATSR aerosol retrieval algorithms installed in Helsinki:
    • FMI: development & services
    • Univ. of Helsinki: development and scientific applications
    • Close cooperation between FMI & UHEL
    • Currently 10 people working on aerosol retrieval (AATSR & OMI)

TEMIS User workshop, Frascati, 8-9 October 2007

developments 2
Developments (2)
  • Familarization (new people)
  • Testing (using 2003 over Europe as test set):
    • Bugs
    • Cloud screening using forest fires Iberian Peninsula 2003
    • Low AOD and low SZA over Finland
  • Development/Improvement:
    • Improved cloud screening
    • Aerosol types & mixtures
    • Bright surfaces
    • Statistical methods to improve reliability and quality

1 x 1 km2

10 x 10 km2

High AOD near cloud edges

10 x 10 km2

  • AOD enhanced near cloud edges due to RH gradients
  • For use in larger pixels, these are not representative, in particular for composite plots over longer time
  • High st. dev. in, e.g. 10x10 km2 pixels
  • Remove to retain uncontaminated data

Developments (3)
  • Application:
    • PO Valley (TEMIS) (user will be contacted when service demonstration ready
    • Netherlands (NL project Satlink, users: TNO & MNP)
    • Europe (NL project HIRAM, users: TNO & MNP)
    • Effects natural aerosol (nucleation) on AOD?
    • AQ in Finland due to forest fires, transport from Russia
    • Aerosol over China (AMFIC)
    • Global aerosol (EUCAARI, GEOMON, MACC)
  • Validation
    • AERONET
    • PFR (WMO)
    • Campaigns

temis progress nrt
TEMIS Progress: NRT
  • Data availability:
    • ftp from Rolling Archive: automated using script
    • RAID: data stored on 2 HD
    • Regular update with new data
    • Example: AOD(670), Po Valley, 6 August 2007

TEMIS User workshop, Frascati, 8-9 October 2007

temis progress nrt1
TEMIS Progress: NRT
  • Automated selection area of interest (Po valley)
  • Inclusion data processing in script
  • QC: manual (later automated?)
    • Comparison with AERONET (Ispra, Venice)
    • Spatial variation and statistics
  • Data presentation on website
    • FMI, link from TEMIS website
    • TEMIS website – examples
  • Data description and background info
  • User feedback:
    • Data presentation
    • Data use and use-ability

TEMIS Progress
  • Improvements:
    • Aerosol models tuned to PO valley (a priori)
    • Mixing ratio
    • Cloud screening
    • Extension to other regions:
      • Europe for TNO & NILU (EMEP)
      • Finland / Russia forest fires
      • Contact with NERI (DK)
