2 Context: IDEAS+ support contract (ESA/ESRIN SPPA) and PANDONIA project (ESA) Purpose: Joint instrumental suite for validating the satellite atmospheric composition and optical products (level 2), and for Planetary Boundary Layer (PBL) studies. Super Site concept: ground based active and passive instruments operating in synergy offering qualitative and quantitative information for a wide range of atmospheric parameters in a urban/rural atmospheric boundary layer BAQUNIN instruments: LIDAR, Raman and elastic, day/night (aerosols, H 2 O, clouds) SODAR day/night (wind profiles in PBL) MFRSR radiometer (aerosols, O 3, H 2 O) POM 01 L PREDE sun-sky radiometer (aerosols, H 2 O) BREWER spectrophotometer (O 3, SO 2, NO 2 ) PANDORA Spectrometers (O 3, NO 2, H 2 O, aerosols) CIMEL photometer (aerosols) YES broad-band UV radiometer (UV radiation) Meteorological sensors (air temperature and relative humidity) Urban Urban Urban Urban Urban Urban+Rural Rural Urban Urban Also available: soundings from Aeronautica Militare (Pratica di Mare, 00:00 and 12:00 UTC) 5-6/07/2016 IDEAS+ TASK3 Workshop, ESA/ESRIN 2

3 BAQUNIN Data: the atmospheric data acquired during BAQUNIN lifetime will be made available to the scientific community, and will contribute to the validation of the aerosol and tropospheric trace gases products produced by the Copernicus Sentinel-5p, Sentinel-4 and Sentinel-5 and by the ESA Third Party Missions (TPM), such as the ozone Monitoring Experiment (OMI).

4 Strategy for Satellite Validation 1) All instruments (except Lidars) operate continuously 2) If possible, synchronisation of operations 3) Satellite(s) overpass info: date, time, footprint, line-of-sight, solar angles 4) Pandora operated in order to maximise FOV overlap at overpass 5) Lidars switched on 2 hours before overpass time (+2 hours after) 6) Most of the acquired data processed in near-real-time 7) Satellite and BAQUNIN data stored on 16 TB NAS Strategy for UBL studies 1) Campaign-based 2) All instruments operate continuously (lidar+sodar: day&night) 3) If possible, synchronisation of operations 4) Off-line processing 5) Data analysis 5-6/07/2016 IDEAS+ TASK3 Workshop, ESA/ESRIN 4

12 Elastic Lidar Univ. Rome Sapienza Backscattering ratio is the backscattering by particle vs. total scattering, or the scattering of light back towards the emission source (the lidar) vs. the scattering of light in another direction. 5-6/07/2016 IDEAS+ TASK3 Workshop, ESA/ESRIN 12

17 Outlook In addition to mentioned instruments, we could also: 1) Make use of the Weather Research and Forecasting (WRF) Model, tailored for Tiber Valley, already installed on ESRIN workstation and used for lee waves study, run by Enrico Cadau (SERCO). The WRF-CHEM model could be also installed and run in support of in-situ/remote sensing measurements. 2) Collaborate with CIRAS (CNR Isac Rome Atmospheric Supersite) lidar, sodars, cimel, anemometers, etc. (Tor Vergata).

18 Summary 1) ESA / IDEAS+ super site 2) Air quality instruments located in urban/rural environment 3) Measurement strategy for Satellite Atmospheric Chemistry Validation 4) Urban Boundary Layer studies Some instruments to be properly calibrated (e.g. Pandora, Cimel), Lidars are undergoing final tuning. The overall system should be ready for operation before the launch of S5p. 5-6/07/2016 IDEAS+ TASK3 Workshop, ESA/ESRIN 18
