1 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Calibration Test Sites Selection and Characterisation WP 240 Equipment and auxiliary data Final Meeting ESA/ESTEC – 2009/04/21

2 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery WP250 – Interest of a Group of Equipped sites Objectives : provide a list of equipment and auxiliary data required per site classes and the operational conditions of use. Instruments and protocole Cost (Instrument and campaign) Data access LES : Land Equipped Site SES : Sea Equipped Site LNES : Land Non Equipped Site SNES : Sea Non Equipped Site

3 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Need for LES Measurement to do Atmospheric state Instantaneous measurements Langley plots AOT Integrated water vapour content Ozone content Radiance and irradiance Total and diffuse downwelling irradiance (hemispherical) Upwelling and downwelling radiance (directional) Surface directional spectral reflectance Environmental parameters Air pressure, temperature and relative humidity Wind speed Soil moisture

6 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Protocol Weather station : automatic Sunphotometer : protocol described on AERONET web pages Direct sun measurement Sky radiance Almucantar Radiometers Sample strategy

7 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Instrument cost

8 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Preparation and data analysis

9 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Mission cost

10 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Maintenance cost

11 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Data Access LSPEC Frenchman Flats measurements are on line

12 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Need for SES Atmospheric state Instantaneous measurements Langley plots AOT Integrated water vapour content Ozone content Marine reflectance downwelling irradiance upwelling irradiance water leaving radiance Sky radiance Chlorophyll concentration Environmental parameters Air pressure, temperature and relative humidity Wind speed

13 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery WP 240 - Instruments

14 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery SES instrument

15 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery

16 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Instrument cost

17 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Preparation and data analysis

18 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Mission cost

19 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Data access All data acquired at SES are available on Internet

20 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Provision of Auxiliary data for SNES and LNES LNES need Pressure Water vapour content Ozone content Site BRDF Aerosol SNES need Pressure Water vapour content Ozone content Water leaving radiance Aerosol

21 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Provision of Auxiliary data for LNES Meteorological data Source Meteorological institutes Land Aerosol : No data Surface BRDF Use Polder database Use SADE Use specific angular conditions

22 Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Provision of Auxiliary data for SNES Data available in the climatological database Chlorophyll content estimated from MERIS level 3 products Aerosol model estimated from MERIS level 3 products Meteorological data Pressure, water vapour content and ozone are provided within the satellite data and are issue from Meteorological center (ECMWF, NCEP etc) Level 3 Aerosols Two suggestions have been made in WP 220 to develop a L3 AERONET database AERONET can be used to propose a climatology of the aerosol models (among SAMs). AERONET can be used to build a local climatology of the aerosol inherent optical properties Aerosol from AERONET network Use of L1 AERONET data One suggestion has been made in WP 220. AERONET CIMEL can be used as well in the satellite match ups for: Flagging the situation with too high aerosol turbidity. Selecting a SAMs, through the Angstroem coefficient in the NIR. Using the CIMEL AOTs in the blue. Some potential site candidates have been listed in WP 220.
