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 Atmospheric Science Conference, ESRIN, 8-12 May 2006 ADM-Aeolus: Measurement Concept (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) Atmospheric Science Conference, ESRIN, 8-12 May 2006 ADM-Aeolus: The Orbit • Altitude: 400 km • Sun-synchronous • Dawn-dusk Atmospheric Science Conference, ESRIN, 8-12 May 2006 ADM-Aeolus: Performance ADM-Aeolus Performance Simulation - Reference Atmosphere 30 28 26 24 22 20 18 16 specification 14 Altitude (km) Altitude 12 10 8 6 4 2 0 0 0.5 1.0 1.5 2.0 2.5 3.0 Wind noise error (HLOS - m s-1) 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.
