Atlas of 3D Eddies in the Mediterranean Sea from 2000 to 2017

& Le Vu Briac
Atlas of mesoscale eddies and their 3D characterization in the Mediterranean Sea for the years 2000-2017. This data-set was obtained from the dynamical analysis of the geostrophic surface currents time-series provided by DUACS/AVISO (https://duacs.cls.fr/) and computed from the delayed-time Absolute Dynamical Topography maps at 1/8°. First, the cyclogeostrophic velocity field was computed from the geostrophic surface current in order to take into account the ageostrophic velocity components induced by the streamlines curvature. Such correction might...

ORCHIDEE-LEAK revision 5919

Ronny Lauerwald
Exports of terrestrial carbon (C) through the river network of the Amazon basin are non-negligible for its C budget, but have to date been ignored in land surface models used for future projections. Here, we utilize a new land surface model that simulates the coupled evolution of the terrestrial C balance and river C fluxes from 1860 to 2100. The terrestrial net-uptake of atmospheric CO2, the terrestrial C storage, but also the leakage of terrestrial...

3D models of planetary bodies

Frederic Schmidt, Gaspard Salomon & Laurent Daumas
Current technology allows us to print various object in 3D for teaching and education purposes, including for the visually disabled [1]. The use of 3D printer for planetary science has been perceived since the premises of this industrial revolution [2]. In parallel several services and web-services have been developed to help the users to create their own model [3]. We propose here a database of ready-to-use 3D model of planetary bodies at full scale.

GEOring calibration coefficients

Thomas Fiolleau & Rémy Roca
Infrared (IR) observations from the fleet of multi-agencies meteorological geostationary satellites have a great potential to support scientific and operational investigations for high cold cloud studies at a quasi-global scale. Yet such a data record, referred as the GEOring dataset, is far from being homogeneous preventing the realization of its potential. This dataset provides the regression coefficients to homogenized the infrared data of various geostationary platforms against the Megha-Tropiques/ScaRaB channel-4 measurements from 1 January 2012...

Aerosol indirect effect sensitivities

Da Silva Nicolas
Simulations were done with the version 3.7.1 of the Weather Research and Forecasting Model (WRF, Skamarock et al., 2008) . The model was run with a 50 km (LR, d01), a 16.6 km (MR, d02) and a 3.3 km (HR, d03) horizontal resolution. It is forced by the Global Forecast System (GFS) model (National Centers for Environmental Prediction National Weather Service, 2000) as initial and boundary conditions. Temperature, humidity, geopotential and velocity components are nudged...

LMDz-REPROBUS model outputs for Eocene and preindustrial stratospheric conditions from Szopa et al. 2019

S Szopa, R Thiéblemont, S Bekki, R Botsyun & P Sepulchre
The stratospheric ozone layer plays a key role in atmospheric thermal structure and circulation. Although stratospheric ozone distribution is sensitive to changes in trace gases concentrations and climate, the modifications of stratospheric ozone are not usually considered in climate studies at geological time scales. Here, we evaluate the potential role of stratospheric ozone chemistry in the case of the Eocene hot conditions. Using a chemical-climate model.,we show that the structure of the ozone layer is...

Dataset for James publication by Hourdin et al 2019 : « Unified parameterization of convective boundary layer transport and clouds with the thermal plume model »

Frédéric Hourdin &
The representation of stratocumulus clouds, and of the stratocumulus to cumulus transitions which are ubiquitous features of marine boundary layer clouds, remains a challenge for climate models. We show how a mass-flux representation of boundary-layer convective structures combined with an eddy-diffusivity scheme, the "thermal plume model", first developed to represent cumulus clouds, can also adequately simulate stratocumulus and the stratocumulus to cumulus transition in a climate model. To achieve this, the detrainment formulation, in which...

Sea surface temperature and precipitation from two simulations of the TRHOL project, from 6000 Before Present to 1950 CE

Pascale Braconnot, Olivier Marti, Yves Balkanski, Julien Crétat, Arnaud Caubel, Anne Cozic, Marie-Alice Foujols & Sidiki Sanogo
Particularly dry or wet boreal summer monsoon seasons are major hazards affecting societal vulnerability in India and Africa. Several factors affect monsoon rainfall amount and limit their understanding. Here we characterize the multiscale variability of Indian and West African monsoon rain from two simulations of the last 6000 years. Changes in Earth’s orbit cause long-term monsoon drying trend, but the Indian monsoon is more sensitive to anthropogenic CO2. Variability is characterized by two major ranges...

Martian Year 34 Climatology of the Atmospheric Column Dust Optical Depth

Luca Montabone, Ehouarn Millour, François Forget, Aymeric Spiga , David Kass & Armin Kleinböhl
We provide a climatology of airborne dust for Martian year 34 using observations of the Martian atmosphere from May 2016 to March 2018 made by the Mars Climate Sounder (MCS) aboard Mars Reconnaissance Orbiter (MRO). Our methodology works by gridding the available estimates of column dust optical depth (CDOD) from MCS limb observations. The resulting (irregularly) gridded maps were validated with independent observations of CDOD by the Mars Color Imager camera aboard MRO, and by...

Monthly 3D outputs of ocean biogeochemical tracers and ocean physical variables in the simulations piControl and RCP8.5 made with the IPSL-CM5A-LR model

Jean-Louis Dufresne, Marie-Alice Foujols, Sébastien Denvil & Damien Couespel
Monthly 3D outputs of ocean biogeochemical tracers and ocean physical variables in the simulations piControl and RCP8.5 made with the IPSL-CM5A-LR model. These outputs are used to compute oxygen subduction and estimate respiration below the mixed layer depth between 1990 and 2099. The methodology requires monthly outputs which were not part of the CMIP5 output protocol and therefore are not availble in the ESGF archive.

CCI+Sea Surface Salinity v1

Jacqueline Boutin &
Sea Surface Salinity (SSS) is an Essential Climate Variable (ECV) that plays a fundamental role in the density-driven global ocean circulation, the water cycle, and climate. The satellite SSS observation from the Soil Moisture and Ocean Salinity (SMOS), Aquarius, and Soil Moisture Active Passive (SMAP) missions have provided an unprecedented opportunity to map SSS over the global ocean since 2010 at 40-150km scale with a revisit every 2 to 3 days. This observation capability has...

ORCHIDEE_gmd-2018-261

Nicolas VUICHARD
Nitrogen is an essential element controlling ecosystem carbon (C) productivity and its response to climate change and atmospheric [CO2] increase. This study presents the evaluation – focussing on gross primary production (GPP) – of a new version of the ORCHIDEE model that gathers the representation of the nitrogen cycle and of its interactions with the carbon cycle from the OCN model and the most recent developments from the ORCHIDEE trunk version. We quantify the model...

ORCHIDEE-GMv3.2

ORCHIDEE is a process-based ecosystem model developed for simulating carbon, water and energy fluxes in ecosystems, from site level to global scale. ORCHIDEE-GM is a version specifically developed to integrate the management of grassland. The equations describing management in ORCHIDEE are derived from PaSim? model. Accounting for the management practices such as mowing, livestock grazing and fertilizer application on a daily basis, ORCHIDEE-GM proves capable of simulating the dynamics of leaf area index, biomass, and...

ORCHIDEE_PEAT_V2

The importance of northern peatlands in the global carbon cycle has been recognized, especially for long-term changes. Yet, the complex interactions between climate and peatland hydrology, carbon storage and area dynamics make it challenging to represent these systems in land surface models. This study describes how peatland are included as an independent sub-grid hydrological soil unit (HSU) into the ORCHIDEE-MICT land surface model. The peatland soil column in this tile is characterized by multi-layered vertical...

APIFLAMEv2 biomass burning emissions model

Solène Turquety
The APIFLAMEv2 software allows the calculation of emissions of trace gases and aerosols from biomass burning. It is based on the fire detection and vegetation type observations by the MODIS Terra and Aqua satellites. For each fire and associated vegetation type, the consumed fuel is calculated and the corresponding emissions of trace gases and aerosols are derived using a list of emission factors.
