5-6/07/2016 IDEAS+ TASK3 Workshop, ESA/ESRIN 1
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, H2O, clouds) Urban
SODAR day/night (wind profiles in PBL) Urban
MFRSR radiometer (aerosols, O3, H2O) Urban
POM 01 L PREDE sun-sky radiometer (aerosols, H2O) Urban
BREWER spectrophotometer (O3, SO2, NO2) Urban
PANDORA Spectrometers (O3, NO2, H2O, aerosols) Urban+Rural
CIMEL photometer (aerosols) Rural
YES broad-band UV radiometer (UV radiation) Urban
Meteorological sensors (air temperature and relative humidity) 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
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).
BAQUNIN instruments and national/international networks:
PANDORA → PANDONIA
CIMEL → AErosol RObotic NETwork (AERONET )
POM 01 PREDE → European Skynet Radiometers (ESR)
BREWER → European Brewer Network (EuBrewnet)

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

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.

The backscatter coefficient is defined as the differential scattering cross section
per unit volume for a scattering angle of 180°.

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). CIRAS website:

Summary
5-6/07/2016 IDEAS+ TASK3 Workshop, ESA/ESRIN 18
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.
