Atmospheric Science Conference, ESRIN, 8-12 May 2006 ADM-Aeolus
Atmospheric Science Conference, ESRIN, 8-12 May 2006 ADM-Aeolus: The Mission
What are the scientific objectives? Improve understanding of – Atmospheric dynamics and global atmospheric transport – Global cycles of energy, water, aerosols, chemicals
How are they achieved? – Better analysis of the atmospheric state to provide a more complete (three-dimensional) picture of the dynamical variables
What are the benefits? – Improved parameterisation of atmospheric processes in models – Advanced modelling of climate and atmospheric flow – Better initial conditions for weather forecasting – Demonstration of ADM-Aeolus’ potential for full operational use
Atmospheric Science Conference, ESRIN, 8-12 May 2006 Existing wind field information
Wind field information available to date in the Global Observation System (GOS): – Radiosonde and pilot soundings (NH continents dominate)
– Aircraft data (NH densely populated areas dominate) – Atmospheric motion vectors (only in the presence of clouds and tracers) – Satellite soundings of temperature and humidity from Polar orbiting satellites (mass information, indirect measure of large-scale phenomenon wind outside the tropics) ÄNo DIRECT, GLOBAL and UNIQUE measurements of atmospheric wind fields yet

(Aladin)
[H]LOS
• Wind measurements are derived from the Doppler shifted signal that is back- scattered by aerosols and molecules along the lidar line-of-sight (LOS)

• Altitude: 400 km • Sun-synchronous • Dawn-dusk

Atmospheric Science Conference, ESRIN, 8-12 May 2006 Additional Benefits from ADM-Aeolus
In addition to the main wind observation product, the following information can be retrieved:
• Clouds ¾ Cloud heights ¾ Multi-layer clouds ¾ Optical thickness ¾ Cloud type
• Tropospheric aerosol ¾ Optical thickness ¾ Aerosol type (lidar ratio - separating anthropogenic from natural) ¾ Stratification
• Wind variability, clear air turbulence • Validation of products from other satellites • Model validation
Atmospheric Science Conference, ESRIN, 8-12 May 2006 Science Benefits from ADM-Aeolus
• More direct observations of winds in the tropics and over mid-latitude oceans
• Use of observations in model verification
• Better description of transports (ozone, humidity, aerosols,…)
• Dynamics in the lower stratosphere
Atmospheric Science Conference, ESRIN, 8-12 May 2006 EarthCARE: Rationale
Earth Clouds, Aerosols and Radiation Explorer - a joint ESA/JAXA mission
Top Of the Atmosphere (TOA) incoming and outgoing radiances are rather well known from ERB instruments (ERBE,CERES, ScaRaB,…)
Why a Mission Like EarthCARE ?
Processes within the atmosphere controlling incoming and outgoing TOA radiances, hence the Earth energy budget at TOA are largely unknown.
Atmospheric Science Conference, ESRIN, 8-12 May 2006 EarthCARE: Mission Summary Scientific objective : Quantification of aerosol-cloud-radiation interactions so they may be included correctly in climate and NWP models, by providing :
ÎVertical profiles of natural and anthropogenic aerosols on a global scale, their radiative properties and interaction with clouds. ÎVertical distribution of atmospheric liquid water and ice on a global scale, their transport by clouds and radiative impact. ÎCloud overlap in the vertical, cloud-precipitation interactions and the characteristics of vertical motion within clouds. ÎThe profiles of atmospheric radiative heating and cooling through a combination of retrieved aerosol and cloud properties.

The mission would cover three environmental issues: ¾ Stratospheric Ozone and Surface UV ¾ Air Quality ¾ Climate
For each theme, three different kinds of applications / users: ¾ Monitoring of international protocols, national legislation ¾ Near-real-time services, such as forecast ¾ Assessments supporting future policy decisions
Individual applications are then mapped against the environmental issues
Observational requirements defined for each application and environmental issue, both for space and non-space data
