Jean-Luc Widlowski,Malcolm Taberner,Bernard Pinty,Véronique Bruniquel-Pinel,Mathias Disney,Richard Fernandes,Jean-Philippe Gastellu-Etchegorry,Nadine Gobron,Andres Kuusk,Thomas Lavergne,Sylvain G. Leblanc,Philip Lewis,Eric Martin,Matti Mõttus,Peter North,Wenhan Qin,Monica Robustelli,Nadia Rochdi,Rosario Ruiloba,Cyril Soler,Richard L. Thompson,Wouter Verhoef,Michel M.

TL;DR: An assessment of the self-consistency and the relative and absolute performance of 3-D Monte Carlo models in RAMI-3 supports their usage in the generation of a "surrogate truth'' for all RAMI test cases.
Journal ArticleDOI
RAMI4PILPS: An intercomparison of formulations for the partitioning of solar radiation in land surface models

TL;DR: The RAMI4PILPS suite of virtual experiments assesses the accuracy and consistency of the radiative transfer formulations that provide the magnitudes of absorbed, reflected, and transmitted shortwave radiative fluxes in LSSs as discussed by the authors.

TL;DR: In this paper, the OSI-450, SICCI-25km and SicCI-50km climate data records are derived from passive microwave satellite data and offer three distinct advantages compared to existing records: first, all three records provide quantitative information on uncertainty and possibly applied filtering at every grid point and every time step.

TL;DR: In this article, a hybrid approach is suggested to retrieve sea ice concentration globally for climate monitoring purposes, which consists of a combination of two algorithms plus dynamic tie points implementation and atmospheric correction of input brightness temperatures.
Journal ArticleDOI

TL;DR: In this article, the quality and accuracy of the fraction of absorbed photosynthetically active radiation (FAPAR) products generated from an analysis of Sea-viewing Wide Field-of-view Sensor (SeaWiFS) data are discussed.
