2024 C2OMODO: A Tandem of Innovative Radiometers for High Resolution All-Sky Atmospheric Sounding as Part of the AOS Mission
abstract
Convective systems are responsible for energy transfers between the lower and upper atmospheric layers and play a fundamental role in the water cycle, weather and climate evolution. With a tandem of high resolution and wide swath all-sky atmospheric sounders, the C2OMODO concept allows the estimation of vertical dynamics within deep convective systems.

2023 A New High Spatial Resolution Interferometric Radiometer for L-Band Earth Observation
abstract
This paper reports on the main results of SMOS-HR instrument technical study, a new interferometric radiometer dedicated to Soil Moisture and Ocean Salinity measurement from space. The instrument aims at providing enhanced spatial resolution with respect to SMOS and integrating robust RFI (RF Interference) mitigation technique. The instrument key performance requirements and the architecture features and trade-offs are exposed in this paper.

2022 The New Generation High Resolution All-Sky Atmospheric Sounder Saphir-NG
abstract
In the continuity of the existing SAPHIR microwave radiometer on-board Megha-Tropiques, in operation since 2011, a new generation atmospheric sounder is currently under study. SAPHIR-NG is designed to provide enhanced observations of clear sky water vapor and profiles of hydrometeors. The scientific objectives and requirements, as well as the instrumental implementation are described.

2021 SAPHIR-NG High Resolution Microwave Sounder: Towards an Enhanced Observation of the Atmosphere
abstract
SAPHIR-NG is a new generation atmospheric sounder concept based on the existing SAPHIR instrument, onboard Megha-Tropiques, which has been operating since 2011. Its improvements with respect to SAPHIR are presented hereafter, both in terms of scientific objectives and instrumental architecture.

2011 An advanced multi-frequency radiometer for GPM Br Fr mission
abstract
This paper presents an advanced multi-frequency radiometer fro the GPM Br Fr mission. This mission will increase the capability of the Megha Tropiques mission. In addition to the MADRAS channels, this radiometer includes the 183 GHz H20 line and some sub-millimeter wave channels for ice cloud characterization (from 243 GHz up to 664 GHz).

2002 Two-dimensional synthetic aperture images over a land surface scene
abstract
The Soil Moisture and Ocean Salinity (SMOS) space mission is currently undergoing phase-B studies at the European Space Agency. The SMOS payload is an L-band interferometric radiometer based on a two-dimensional aperture synthesis concept. This paper presents the first images obtained by a demonstrator of the SMOS instrument over land surfaces at the Avignon test site in 1999.
