In this first phase, our G3W team is looking after the implementation & sustainability strategy, linking with the various constituent bodies and reporting progress to the WMO Executive Council and to WMO Secretariat.The development of the G3W spans across all technical departments of WMO, leveraging on collaboration within the organisation, as well as with entities outside the core of WMO National Meteorological and Hydrological Services, including other Government Agencies, fellow UN agencies and representatives from Academia as well as the Private-sector, both for profit companies and philanthropies. G3W is placed within the Infrastructure Department, and with strong linkages with the Science and Innovation Department.Among my duties there is the formulation and management of the work programme in support G3W activities and connected relevant activities such as the Joint Study Group composed of worldwide leading scientists working on Greenhouse Gas GHGs Monitoring.

As Principal Scientist I have been contributing to the research output of ECMWF with focus on Earth's biosphere, cryosphere and hydrosphere. These elements of the Earth system are represented using a range of models to simulate the energy/water/carbon cycle continuous exchanges with atmosphere, that can support extended range prediction capabilities, via Coupled Processes (CP).

These elements of the Earth system are represented using a range of models to simulate the energy/water/carbon cycle continuous exchanges with atmosphere, that can support extended range prediction capabilities, via Coupled Processes (CP). Collaborations and Partnerships support the modelling research via numerous international actions involving the ECMWF Member-States, the European Commission Copernicus & Research Programmes, European Satellite Agencies and active participation in World Meteorological Organisation's Committees.As Team-Leader I have been responsible for the Coupled Processes (CP) Group, part of the Earth System Modelling (ESM) Section of the Research Department (RD) at ECMWF. Our role as a Team consisted in adopting new advances in parameterizations for land/ocean thermodynamics, currents/waves/surface-atmosphere interaction and biogeochemistry processes, that are most relevant to produce accurate forecasts on a range of lead-time between a day and a year ahead. Natural/Anthropogenic surfaces and their distribution are described with the aid of satellite remote sensing information.Our Team research and development aimed at improved understanding of surface processes and a more seamless coupling of the different Earth system components to enhance the accuracy/usefulness of weather/environmental predictions and climate reanalysis.Among the significant publications during this period of work, the ERA5 C3S Climate reanalysis supporting the Copernicus State of Climate and the CAMS Greenhouse Gas reanalysis:Hersbach et al., 2020: The ERA5 global reanalysis, Quarterly Journal of the Royal Meteorological Society, https://rmets.onlinelibrary.wiley.com/doi/10.1002/qj.3803Agusti-Panareda, A. et al., 2023: The CAMS greenhouse gas reanalysis from 2003 to 2020, EGUsphere, https://doi.org/10.5194/acp-23-3829-2023 Show less

The first and most significant tasks have been the redesign and implementation of the new Hydrology - Tiled ECMWF Surface Scheme for Exchanges over Land (H-TESSEL) that included major additions and revisions in all the hydrologically active surface components. H-TESSEL became operational in November 2007 and it has been continuously improved in each of the subsequent Integrated Forecasting System’s cycles, with a growing Team of developers, both at ECMWF and in collaboration with Partners Research Institutes.

I was employed by the French National Research Center for Meteorology CNRM for the participation to the European project ELDAS which contributed to build a European Land Data Assimilation System to be used across regional and global models. After the development of a novel simplified bidimensional variational technique during my PhD, I have applied this method to both the regional & global numerical weather prediction models used operationally at Météo-France. The method was targeted for the soil moisture analysis but had elements of generality and at the end of my postdoctoral studies I was invited to implement and expand this methodology within the Canadian model at Environment and Climate Change Canada from January 2004.key publication:Balsamo, G., Bouyssel, F. and Noilhan, J., 2004, "A simplified bi-dimensional variational analysis of soil moisture from screen-level observations in a mesoscale numerical weather prediction model", Quart.

Employed under the Interreg France-Italy programme I was integrated in the Hydrometeorological Service unit of the Piedmont Region.Among the significant operational contributions I had monitored progress in the construction of a meteorological C-band radar at Mt Settepani and the initial setup of the Sestriere Weather-room in preparation of the Winter Olympic Games forecasting services. As weather forecaster I was responsible for issuing daily bulletins with detailed forecasts for the next 3-days and provide daily briefings. I have supported several flooding alerts during Summer/Autumns 1999/2000/2001 in coordination with the national and regional civil protection, and the Italian Member-state Aeronatica-Militare.My support to the research community started with the participation to the international Mesoscale Alpine Programme MAP in 1999, where I had joined the Intense Observation Periods guiding the operational planning of instrumented flights from the Milan Linate airport. I was also involved in land surface modelling applied research for agrometeorological applications which later became my PhD topic at Météo-France to develop a novel methodology to analyse the soil moisture in regional and global models used for operational weather forecasting.
