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)

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

7
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

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

• 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

12
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

13
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)

14
Time Schedule

• NRT implementation and demonstration October -
  November 2007
• User interaction November 2007
• New User other area (Finland?)? End of 2007
• Improvements
• Aerosol models End of 2007
• Cloud screening tbd
