DUP-TEMISWP2.6 Regional Aerosol Gerrit de Leeuw, FMI/UHEL/TNO Pekka Kolmonen, FMI Robin Schoemaker, TNO
Objective Retrieval, implementation and validation of the regional tropospheric product for aerosols TEMIS User workshop, Frascati, 8-9 October 2007
Workplan WP 2.6 Regional aerosol Activity: Extending of the ATSR-aerosol service: Demonstration of a data delivery service for the Po-Valley. Time period: January 2005 – December 2007 Responsible TNO-DSS TEMIS User workshop, Frascati, 8-9 October 2007
Workplan WP 2.6 Regional aerosol Activity Extending of the ATSR-aerosol service: Demonstration of a data delivery service for the Po-Valley. Time period January 2005 – December 2007 Responsible TNO-DSS FMI TEMIS User workshop, Frascati, 8-9 October 2007
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) • 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 TEMIS User workshop, Frascati, 8-9 October 2007
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) • 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
Spatial distribution of AOD (670), 17 April 2003 TEMIS progress: retrieval TEMIS User workshop, Frascati, 8-9 October 2007
TEMIS progress: Validation vs AERONET Ispra, 12 June 2003 Venice, 2003 TEMIS User workshop, Frascati, 8-9 October 2007
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: 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 • 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) TEMIS User workshop, Frascati, 8-9 October 2007
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 TEMIS User workshop, Frascati, 8-9 October 2007
Users TEMIS user: • PO Valley (TEMIS) (user will be contacted when service demonstration ready Non-TEMIS users: • Europe (NL project HIRAM, users: TNO & MNP) • Netherlands (NL project Satlink, users: TNO & MNP) Work in progress: • 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) Potential future users: NERI (DK), MACC, MEGACITIES and several TEMIS workshop participants that expressed their interst on Day 1 TEMIS User workshop, Frascati, 8-9 October 2007
