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...

ORCHIDEE_CN_CAN revision 5698

Sebastiaan Luyssaert
The search for a long-term benchmark for land-surface models (LSM) has brought tree-ring data to the attention of the land-surface community because they recorded growth well before human-induced environmental changes became important. The most comprehensive archive of publicly shared tree-ring data is the International Tree-ring Data Bank (ITRDB). Records in the ITRDB have, however, been collected almost exclusively to reconstruct past climate and hydrological variability, which may limit its use as a data source for...

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...

Monthly Iorg index of deep convective organization across the tropical belt (30S-30N)

Sandrine Bony & Addisu Gezahegn Semie
Monthly-mean Iorg index of deep convective organization computed over the tropical belt (30S- 30N) for the period January 1990 to December 2017. The Iorg index is computed by comparing the cumulative density function of the nearest-neighbor distances between deep convective centroids to that expected for a random distribution associated with a Poisson process. The deep convective centroids are identified from 3-hourly GridSat geostationary data using the local minima method. The monthly-mean Iorg is the monthly...

Daily gridded precipitation observational products at 1°x1°: ground-based, satellite, and reanalysis datasets

Rémy Roca
This database includes multiple precipitation estimates from ground-based, satellite and reanalysis products, gridded at the 1x°xdaily resolution in a common format in support of the various WCRP precipitation assessment (GEWEX Data Analysis Panel, GC on Extremes,...).

Simulations of the HDO cycle with LMD Mars GCM

We present here simulations of the HDO cycle on Mars, using the LMD Mars GCM. They show the water and HDO cycles, following the reimplementation of tracers related to HDO in the model. In these simulations, the cloud formation is done assuming a simplified scheme, without the details of the condensation nuclei. Clouds are not radiatively active. Two dust scenarios are available: one for the climatology scenario (representative of an average year on Mars), one...

ORCHIDEE-MUSLE revision 6129

Global water erosion strongly affect the terrestrial carbon (C) balance. However, this process is currently ignored by most global land surface models (LSMs) that are used to project the responses of terrestrial C storage to climate and land use changes. One of the main obstacles of implementing erosion process in LSMs is the high spatial resolution needed to accurately represent the effect of topography on soil erosion and sediment delivery to rivers. In this study,...

APIFLAMEv2 biomass burning emissions in Europe during the Summer 2016

Solène Turquety
APIFLAME biomass burning emissions for the case of the Summer of 2016 in Europe, including large fires in Portugal in August. The dataset includes burned area estimated based on the MODIS fire observations observations (MCD64, MOD14) using the APIFLAMEv2 software. Two datasets are provided. AB_FRP_MODIS includes ascii files of burned area at 500m resolution (MODIS MCD64) and fire radiative power (FRP) at 1km resolution (MODIS MOD14). AB_FRP_MODIS_GRIDDED provides netcdf files with gridded (10km) estimates of...

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

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...

ORCHIDEE_DFv1.0_site

Yuan ZHANG
Aerosol and cloud-induced changes in diffuse light have important impacts on the global land carbon cycle by changing light distribution and photosynthesis in vegetation canopies. However, this effect remains poorly represented in current land surface models. Here we add a light partitioning module and a new canopy light transmission module to the ORCHIDEE land surface model (trunk version, v5453) and use the revised model, ORCHIDEE_DF, to estimate the fraction of diffuse light and its effect...
