Quantitative assessment of the potential of optimal estimation for aerosol retrieval from geostationary weather satellites in the frame of the iAERUS‐GEO algorithm

Autor: Adèle Georgeot, Xavier Ceamanos, Jean‐Luc Attié

Publikováno v: Atmospheric Science Letters, Vol 25, Iss 3, Pp n/a-n/a (2024)

Abstract Satellite remote sensing enables the study of atmospheric aerosols at large spatial scales, with geostationary platforms making this possible at sub‐daily frequencies. High‐temporal‐resolution aerosol observations can be made from geos

In Situ VTOL Drone-Borne Observations of Temperature and Relative Humidity over Dome C, Antarctica

Autor: Philippe Ricaud, Patrice Medina, Pierre Durand, Jean-Luc Attié, Eric Bazile, Paolo Grigioni, Massimo Del Guasta, Benji Pauly

Publikováno v: Drones, Vol 7, Iss 8, p 532 (2023)

The Antarctic atmosphere is rapidly changing, but there are few observations available in the interior of the continent to quantify this change due to few ground stations and satellite measurements. The Concordia station is located on the East Antarc

Publikováno v: Remote Sensing, Vol 14, Iss 6, p 1403 (2022)

Nitrous oxide (N2O) is a greenhouse gas difficult to estimate by satellite because of its weak spectral signature in the infra-red band and its low variability in the troposphere. Nevertheless, this study presents the evaluation of new tropospheric N

Supercooled liquid water clouds observed over Dome C, Antarctica: temperature sensitivity and surface radiation impact

Autor: Philippe Ricaud, Massimo Del Guasta, Angelo Lupi, Romain Roehrig, Eric Bazile, Pierre Durand, Jean-Luc Attié, Alessia Nicosia, Paolo Grigioni

Clouds affect the Earth climate with an impact that depends on the cloud nature (solid/ liquid water). Although the Antarctic climate is changing rapidly, cloud observations are sparse over Antarctica due to few ground stations and satellite observat
