  1. Atmospheric Data from ESA C. Zehner (ESA)

  2. OUTLINE • ERS and ENVISAT missions • ESA Atmospheric Instruments • ESA Atmospheric Data

  3. 1990 2000 2004 2010 Meteo METEOSAT Second GenerationMSG-1, -2, -3 METEOSATM-1, 2, 3, 4, 5, 6, 7 in cooperation with EUMETSAT Science (Gravity and Ocean Circulation Explorer) to better understand the Earth GOCE Earth Explorers ADM/Aeolus Sentinel 4/5 SMOS Sentinel 1 Sentinel 2/3 SWARM Earthcare CryoSat 2 (Polar Ice Monitoring) Applications Services to initiate long term monitoring systems and services Earth Watch Earthnet:European access to non-ESA missions: Landsat, SeaWifs, NOAA, JERS, MODIS, ALOS, Proba, Bird, Scisat, OMI ... European users Since 1977 METOP-1, -2, -3 ERS-1, -2 ENVISAT GMES in cooperation with EC

  4. ERS Missions ERS-2 ERS-1 • 17 years of ERS-1/2 data in archive • ERS-2: achieved 12 years in orbit in April 2008 (3 years nominal lifetime) • Some problems with the platform (gyroscope in 2001, tape recorder in 2003),  engineering solutions • All instruments still functioning well • Seeking operations funding until 2010 (ensured by the end of 2008)

  5. Global Ozone Monitoring Experiment (GOME) Operational on ERS-2 since April 95 (predecessor of GOME follow on Instruments on the operational METOP Series, GOME is a small version of SCIAMACHY on ENVISAT) GOME is a spectrometer which collects light arriving from the sun illuminated Earth’s atmosphere/surface in nadir view. Spectral coverage: 240 - 790 nm with Spectral resolution: 0.2 - 0.4 nm

  6. GOME Scan Pattern from ERS-2

  7. Accuracy of GOME Ozone Measurements

  8. ENVISAT Mission

  9. Michelson Interferometric Passive Atmospheric Sounder Advanced Along Track Scanning Radiometer Scanning Imaging Absorption Spectrometerfor Atmospheric Cartography Medium Resolution Imaging Spectrometer Microwave Radiometer to Data Relay Satellite Artemis GlobalOzone Monitoring by Occultation of Stars Doppler Orbitography and Radio-positioning Integrated by Satellite to Ground Stations Radar Altimeter 2 Advanced Synthetic Aperture Radar • Launch • 1st March 2002 • Orbit • 800 km, sun synchronous 10:00 am, i.e. 30 minutes before ERS-2

  10. Mission objectives • to provide for continuity of the observations started with the ERS satellites, including those obtained from radar-based observations, • to provide for enhancement of the ERS missions, notably the ocean and ice mission, • to extend the range of parameters observed, to meet the need to increase knowledge of the factors determining the environment, • to make a significant contribution to environmental studies, notably in the areas of atmospheric chemistry and ocean studies (including marine biology).

  11. ENVISAT mission • Largest European satellite & largest worldwide EO satellite: - unique combination of 10 instruments addressing land, ocean, ice and atmosphere studies, - instruments working nominally - some concern with altimeter instrument • Satellite OK with long-term operations capabilities: - 45 % of fuel available (i.e. about 3 years assuming same orbit control strategy: +/- 1 km) • Operations funding until 2010 (extension planned by 2013) • 78 different types of ESA data products • 250 Gigabytes of data products generated per day at ESA (+ telemetry)

  12. MIPAS SCIAMACHY GOMOS Envisat Atmospheric Payload GOMOS: Global Ozone Monitoring by Occultation of Stars MIPAS: Michelson Interferometer for Passive Atmospheric Sounding SCIAMACHY: SCanning Imaging Absorption SpectroMeter for Atmospheric ChartograpHY (AO Instrument, provided to ESA by Belgium, Germany, and The Netherlands)

  13. F(zi) T(zi) = Intensity Intensity Intensity Fo F(z1) F(zi) Transmission Fo Wavelength Wavelength Wavelength Wavelength 3 Complementary Atmospheric Instrumentson Envisat GOMOS will primarily provide highly accurate profiles of stratospheric ozone, preferably at altitudes above 15 km. Additional profiles: NO2, NO3, H2O and Temperature. Fo 60 Km z 40 Km F(z) 20 Km

  14. MIPAS, operating in the mid-infrared, will provide highly accurate temperature profiles and a number of key species including most of the NOx family. Making emission measurements it observes both by day and by night.

  15. SCIAMACHY will make unique measurements for its target constituents (profiles and total columns) throughout the stratosphere and troposphere. It will thereby yield the amounts and distributions of trace gas and aerosol in the troposphere.

  16. tropospheric O3 and its precursors (NOx, CO, H2O, CH4, UVA, UVB...) stratospheric ozone production and destruction cycles the dynamics of the stratosphere tropospheric / stratospheric exchange processes Main Topics to be investigated:

  17. the global distribution of many important greenhouse gases (H2O, CO2, CH4, N2O, CFCs...) in the lower atmosphere and thereby investigate their impact on global climate change the physics and chemistry of the mesosphere tropospheric emissions: air pollution monitoring the improvement of the accuracy of numerical weather prediction, using the global measurements of pressure, temperature fields, H2O and O3 made in near real time

  19. The Atmospheric Data Products delivered by ESA to users: • - level 1B products: geolocated and calibrated at engineering level - calibrated spectra • level 2 products: geolocated at geophysical level - total columns, profiles • higher level products: e.g. global maps - ESA facilitates its generation through dedicated Programmes like DUE, EOMD, or GMES) – no ESA products!
