  1. Discussion Tropospheric MissionSRON, 18 nov 2003 - Update CAPACITY workshop / time schedule - Update Post-MSG UV-VIS instrument Michiel van Weele, KNMI

  2. CAPACITY • Chemistry Applications workshop • 20+21 Jan at ESA-ESTEC • Jointly organized with GMES-GATO final meeting • Definition of workshop program; Speakers / working groups: • Air Quality protocols/ EU directives • Kyoto and Montreal protocols • Science: tropospheric applications • Science: UTLS+stratospheric applications • Poster session: (mainly) capacity partners • Jan – Jun 2004: setting level 2/3 data requirements

  3. Post-MSG activities (2015+) Mission Requirements Document (it should be there): “Specifications for a UV-VIS Hyperspectral Imager” The document is based on: • Table of consolidated user requirements (2002) established at a workshop in 2002 and based on study by Lelieveld (paper copy) • Two UV-VIS studies: by Bremen (Bovensmann) and CSIRO (O Brien), respectively

  4. Post-MSG activities Choices that have been made by Eumetsat already: - Five tropospheric gases remain to drive the UV-VIS-NIR chemistry instrument: CO, O3, NO2, SO2, CH2O - CO2, CH4 out: “6h temporal resolution does not require geo instrument” - Aerosols out: ‘is covered by other instrument study’ - H2O out: idem - Other gases: PAN requirements can not be met

  5. Post-MSG activities Option for a combination of the UV-VIS-SWIR bands with Oxygen A band (from a separate study): Four bands: 755, 761, 764 and 775 nm FWHM: 5,3,6,5 nm Unclear if these reqs. are set for: cloud/aerosol detection, cloud-top/surface pressure determination or light path Hor. Resolution: 3km (to fulfill the 10 km requirement) -----
