Workshop

13 – 17 November 2023 | ESA-ESRIN, Frascati (Rome), Italy

Science and Cal/Val Campaigns – Overview

S. Gross and J. Delanoë (and all PIs)Needs from L2-developers§ Lidar measurements of Mie and Rayleigh signal preferable§ Simultaneous lidar measurements of low depol and high depol measurements§ Depolarization measurements at 355 nm (532 would work with potential additional uncertainties during
conversion)§ Macrophysical properties (PBL height, multi-layer aerosol scenarios, broken clouds and aerosols, multi-layer cloudscenarios§ Run L2 algorithms on airborne and ground-based measurements§ Simulation of non-EC products e.g. to compare with measurements at different wavelengths§ Extinction and IWC/LWC needed (for simulations / closure)§ AOT measurements from ground (e.g. AERONET) and satellite (e.g. MODIS, VIIRS, …)§ Ground-based remote sensing along flight track§ Imager measurements§ Synoptic observations§ In-situ measurements (underflights along EC flight track)§ Airborne microwave measurements§ Polarization radar measurements and precipitation radar scans—> Different meteorological conditions, different clouds, different aerosol situations

Proposed EarthCARE validation in the Mediterranean– MULTIPLY airborne and ground-based lidar/radar measurements
MULTIPLY is an ESA-ESTEC project for the development of a novel multi-wavelength HSRL system (3b + 2a +3d) for both ground based (ready in 2022-phase 1) and airborne operation (phase 2: 2023-2024).
Partners: National Institute of Research and Development for Optoelectronics (Romania), Max-Plank
Institute (Germany), National Observatory of Athens (Greece), Warsaw University (Poland)
Target of the HSRL: better than EarthCARE specifications• raw signals:• 7.5 m vert. res.
• 50 m horizontal res.
• 1-1.5% accuracy• backscatter• 7.5 m vert. res.
• 500 m horizon.res.
• 10% accuracy• detectability 0.0005-0.0008• extinction• 100 m vert. res.
• 5000 m horizontal res.
• 10-15% accuracy• detectability 0.02-0.05• depolarization• 7.5 m vert. res.
• 500 m horizontal res.
• 10% accuracy• detectability 0.02

Main features: 3β + 3α + 3d
• Implementing Fabry-Pérot Interferometersfor HSR filtering at 355 and 1064 nm• Implementing iodine filtering technique at532nm• Narrow field-of-view receiving• Low laser pulse energy (to conform the eyesafety requirements).
• High laser pulse repetition rate (to increase
the total number of sounding photons
emitted to• measure individual lidar profile).
• Decoupling spectral separation unit
(interferometers, iodine filter) fromtelescope with optical• fibers (to allow better mechanical stability).
• Implementing extra telescopes fordepolarization channels.
• Additional “near”-range telescope (to extenddynamic range).
