MIS 3 environmental conditions in Africa north of the Equator and the Arabian Peninsula have long been controversial due to data scarcity and methodological caveats. In this paper we compare 245 continental hydrological records and 11 long and contin

International audience; We propose to use a regional orthogonal Slepian Functions (SF) decomposition to represent and analyse the surface water mass variations sensed by GRACE satellite over the Niger basin. As band-limited Spherical Harmonics (SH) r

International audience; We propose a ''constrained'' least-squares approach to estimate regional maps of equivalent-water heights by inverting GRACE-based potential anomalies at satellite altitude. According to the energy integral method, the anomali

Performances du système SWOT en hydrologie

Autor: Riccio, Maud

Publikováno v: Sciences de l'ingénieur [physics]. 2014

The SWOT mission, resulting of the collaboration between CNES and NASA and planned for 2020, will contribute to a great improvement in continental hydrology thanks to its instrument KaRIN, which is an interferometric SAR with low angle of incidence (
