Descrizione del progetto
Misurazione multispecie avanzata di gas e isotopi correlati ai cambiamenti climatici
Mentre il mondo lavora per mitigare i cambiamenti climatici globali, il monitoraggio dei livelli di GES atmosferici, quali CO2 e CH4, ma anche degli isotopologhi del vapore acqueo, è fondamentale per comprendere il passato, identificare i progressi presenti e prevedere gli effetti futuri. Le previsioni sono alla base delle azioni intraprese sul campo per migliorare la resilienza. L’attuale strumentazione lidar quantifica generalmente una singola specie. Il progetto LEMON, finanziato dall’UE, sta sviluppando una tecnologia avanzata di telerilevamento basata su laser pulsato che supporterà le misurazioni di CH4, CO2 e isotopologhi di vapore acqueo correlate ai cambiamenti indotti dal clima nel ciclo idrologico. Per farlo, dimostrerà il telerilevamento del gas e redigerà un piano d’azione per un futuro strumento spaziale.
Obiettivo
LEMON will provide a new versatile Differential Absorption Lidar (DIAL) sensor concept for greenhouse gases and water vapour measurements from space.
During the last climate conference in Paris in December 2015, climate-warning limits have been discussed and agreed upon. In such frame, the need for a European satellite-borne observation capacity to monitor CO2 emissions at global, European and country scales has been identified, as stated by the Copernicus report “Towards European operational observing system monitor fossil CO2 emissions”.
New space missions are now being used (GOSAT, AIRS, IASI, …) or planned (OCO, IASI-NG, MicroCarb, MERLIN, …) for CO2 and/or CH4. Given the technical challenges, they are up to now mainly based on passive (high resolution spectrometers) instruments, Lidar instrument-based mission (MERLIN) is currently in development in Europe to probe methane only.
Therefore, the main goal of LEMON is to develop a versatile instrument, able to target CO2, CH4 and water vapour stable isotopes (H216O and HDO only, from now on referred to as water vapour or H2O and HDO explicitly) with a single laser emitter.
The consortium consists of ONERA (FR), FAUNHOFFER (DE), CNRS (FR), KTH (SE), SPACETECH (DE), UiB (NO), INNOLAS (DE) and L-UP (FR). It has full expertise at Earth Observation technologies (from receiver, data acquisition, instrument control and versatile emitter) and is therefore able to fully explore, understand and validate the aforementioned advantages. The consortium is highly motivated to set-up and perform demonstrations at all instrument levels in order to showcase the project results. This will include the instrument set-up, TRL6 instrument validation, airborne demonstrations and CO2, CH4, H2O isotopes measurements, as well as roadmaps and preliminary experiments towards space operation.
The LEMON total grant request to the EC is 3 374 725€ for the whole consortium and the project will be conducted within 54 months.
