• OBJECTIVES
• Science. Understand the impact of man-made and
  naturally occurring phenomena in the troposphere
  on a transient and on a diurnal timescale.
• Pollution/air quality (NH), Biomass burning (SH)
• Political. Treaty monitoring and compliance
• (UNCLRTAPair pollution, UNFCCCKyoto)
• Technical. Exploit emerging technology Earth
  Observation from geo stationary orbit (position
  European Industry)
• Programmatic. Earth Watch (GMES, INTRYCATE
  28-02-02)
• EUMETSAT Meteosat Third Generation (2014)

• Typical spatial and temporal scale of atmosphere
  species
• Spatial and temporal variability is inversely
  related to chemical lifetime

• Diurnal variation of several troposphere
  pollutants near London July 1998
• Photo-chem production of ozone during day time by
  oxidation CO in presence of NOx

•    Scientific Mission Requirements
• Total and tropospheric column amounts (incl. PBL)
  of O3, CO, CH4, NO2, SO2, HCHO, C2H6, PAN, BrO,
  H2O, OCS, CO2, N2O
• Tropospheric height resolved information (incl.
  PBL) of O3, CO, CH4, N2O
• Vertical Profiles of H2O, and T
• The radiation field at top of the atmosphere
• Aerosol optical thickness, aerosol layer height
• Cloud top height and cloud cover

• Mission Concept
• Geo-Stationary orbit High temporal (30 mins) and
  high spatial sampling (10 to 25 km) and cloud
  free observation
• UV-vis-NIR-SWIR spectrometry (deep penetration in
  troposphere). Total columns of O3, NO2, SO2, BrO,
  OClO, HCHO, H2O, UV-A, UV-B, cloud and aerosol.
  Troposphere column for O3, NO2, BrO, and HCHO
  (already demonstrated by GOME). UV-SWIR for total
  and vertical column information on CO, CH4, CO2,
  H2O, N2O (SCIAMACHY).
• TIR spectrometry Tropospheric column amounts and
  vertical information on temperature, O3, CO, CH4,
  H2O, N2O, HCHO, C2H6 SO2, and PAN and CFCs
  (heritage ADEOS-IMG, IASI, TES).
• Combination Best possible vertical information at
  high spatial/temporal sampling from passive
  Remote Sensing.

• Climate applications
• Tropospheric ozone, most variable climate gas,
  will continue to rise, expected to become as
  important climate gas as CH4 by 2100, exceeding
  air quality standards in much of NH.
• Aerosol, most variable atmosphere constituent
  (varies hourly with solar zenith angle) Relevant
  to climate change, air pollution and health.
• CO2 and CH4 display significant diurnal variation
  which can be used to separate biogenic from
  anthropogenic component
• Combination with MetOp (GOME and IASI) will
  globally extend GeoTROPE observations

• Meteorological applications
• Stratospheric and Upper Troposheric Ozone as
  tracer for wind fields would improve Numerical
  Weather Prediction (dynamical and chemical)
• Observation of Diurnal variation of ozone would
  improve vertical energy (temperature)
  distribution in NWP models and hence calculation
  of global circulation
