SeaFlux: harmonization of air–sea CO2 fluxes from surface pCO2 data products using a standardized approach

Autor: A. R. Fay, L. Gregor, P. Landschützer, G. A. McKinley, N. Gruber, M. Gehlen, Y. Iida, G. G. Laruelle, C. Rödenbeck, A. Roobaert, J. Zeng

Publikováno v: Earth System Science Data, Vol 13, Pp 4693-4710 (2021)

Air–sea flux of carbon dioxide (CO2) is a critical component of the global carbon cycle and the climate system with the ocean removing about a quarter of the CO2 emitted into the atmosphere by human activities over the last decade. A common approac

Q-Switched and Mode-Locked Nd/Cr:YAG Ceramic Pulse Laser

Autor: T. Saiki, N. Hirota, S. Kanemori, Y. Iida

Publikováno v: International Journal of Optics, Vol 2020 (2020)

A mode-locked and Q-switched short pulse laser using the Nd3+/Cr3+:YAG ceramic has been constructed with a SESAM and Cr4+:YAG crystal optical switch based on excite state absorption (ESA). Laser oscillations of the pulse laser were observed experimen

Publikováno v: Geoscientific Model Development, Vol 10, Pp 2201-2219 (2017)

A four-dimensional variational method (4D-Var) is a popular technique for source/sink inversions of atmospheric constituents, but it is not without problems. Using an icosahedral grid transport model and the 4D-Var method, a new atmospheric greenh

The Southern Ocean is a major sink of atmospheric CO2, but the nature and magnitude of its variability remains uncertain and debated. Estimates based on observations suggest substantial variability that is not reproduced by process-based ocean models
