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

10 x 10 km2

TEMIS User workshop, Frascati, 8-9 October 2007


Developments 3

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 User workshop, Frascati, 8-9 October 2007


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 User workshop, Frascati, 8-9 October 2007


Temis progress

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)
