Dr. Pierre Tabary

Program Manager

Dr. Pierre TABARY was born in France in 1974. He graduated from the Ecole Polytechnique in 1997, from the French School of Meteorology in 1999 and received his PhD (on weather radars) from the University of Toulouse (Paul Sabatier) in 2002. He received entitlement to supervise PhD students by the Institut National Polytechnique (Toulouse) in 2012. Between 2002 and 2015, Dr. TABARY worked at Météo France, the French national weather service, at various R&D and managing positions at the Meteo France Weather Radar Centre, leading several projects aiming at extending and upgrading (Doppler, polarimetry) the French radar network and fostering usage of the data (assimilation, hydrology, nowcasting). Between 2008 and 2012, he acted as Meteo France lead person in the european SESAR (Single European Sky Air Traffic Management Research) project aiming at renewing and modernizing air traffic control management across Europe. Dr. TABARY joined CNES in 2015 as programme manager for Atmosphere Meteorology Climate. As such, in the Atmosphere thematic domain, he oversees from a programme point of view a number of CNES missions, either in definition, development or exploitation (Megha-Tropiques, Calipso, IASI, Strateole-2, IASI-NG to name a few), contribues to elaborating the CNES strategy, within the european and international context, and supporting the French user communities on the preparation and exploitation of space missions.

Abstract of Speech

After some general introductory reminders on the organization and main activities of CNES, the presentation will focus on the long-lasting collaborations between CNES and ISRO in the fied of Earth Observation. Three missions in particular will be highlighted from a scientific, technical and programmatical perspective : Megha-Tropiques, Saral-AltiKa and Trishna, all of them contributing to a better understanding of the water and energy cycle in a changing climate. Megha-Tropiques, launched in 2011, is a satellite dedicated to the study of the energy and water cycle in the tropics. It relies on a suite of instruments (microwave sounders, radiometers, GNSS radio-occultation sensor) providing measurements of precipitation, temperature and humidity up to 5 times a day thanks to the unique tropical orbit of the satellite. Saral-Altika was launched in 2013 and provides measurements of coastlines, inland surfaces (lakes and rivers) and frozen surfaces (sea ice, glaciers, ice caps) thanks to a Ka band altimeter with improved performance. The Trishna mission, scheduled to launch in 2024, will provide images of the whole planet in the visible and infrared domain, with a high geometric resolution (50m), every 3 days with two main scientific goals : ecosystem stress monitoring and water management on the one hand and monitoring and management of coastal zones on the other hand. The presentation will also highlight the Space Climate Observatory, which is an initiative aiming at developping and making available space-based products, resources and services related to climate change and its impacts at the national and territorial levels, and providing indicators to support decision-makers and help them adapt to climate change.
