Scientific Developments and the EPS-SG Scatterometer ArchiMer
Stoffelen, Ad; Aaboe, Signe; Calvet, Jean-christophe; Cotton, James; De Chiara, Giovanna; Saldana, Julia Figa; Mouche, Alexis; Portabella, Marcos; Scipal, Klaus; Wagner, Wolfgang.
The second-generation exploitation of meteorological satellite polar system (EPS-SG) C-band-wavelength scatterometer instrument (called SCA), planned for launch in 2022, has a direct heritage from the successful advanced scatterometer (ASCAT) flown on the current EPS satellites. In addition, SCA will represent three major innovations with respect to ASCAT, namely: 1) Cross polarization and horizontal copolarization; 2) a nominal spatial resolution of 25 km; and 3) 20% greater spatial coverage than ASCAT. The associated expected science and application benefits that led the SCA design are discussed with respect to ocean, land, and sea ice applications for near-real time, climate monitoring, and research purposes. Moreover, an option to implement an ocean...

Remotely Sensed Winds and Wind Stresses for Marine Forecasting and Ocean Modeling ArchiMer
Bourassa, Mark A.; Meissner, Thomas; Cerovecki, Ivana; Chang, Paul S.; Dong, Xiaolong; De Chiara, Giovanna; Donlon, Craig; Dukhovskoy, Dmitry S.; Elya, Jocelyn; Fore, Alexander; Fewings, Melanie R.; Foster, Ralph C.; Gille, Sarah T.; Haus, Brian K.; Hristova-veleva, Svetla; Holbach, Heather M.; Jelenak, Zorana; Knaff, John A.; Kranz, Sven A.; Manaster, Andrew; Mazloff, Matthew; Mears, Carl; Mouche, Alexis; Portabella, Marcos; Reul, Nicolas; Ricciardulli, Lucrezia; Rodriguez, Ernesto; Sampson, Charles; Solis, Daniel; Stoffelen, Ad; Stukel, Michael R.; Stiles, Bryan; Weissman, David; Wentz, Frank.
Strengths and weakness of remotely sensed winds are discussed, along with the current capabilities for remotely sensing winds and stress. Future missions are briefly mentioned. The observational needs for a wide range of wind and stress applications are provided. These needs strongly support a short list of desired capabilities of future missions and constellations.
