This dataset contains a daily precipitation analysis performed using SAFRAN and the full rain gauges database of the Direction Générale des Resources en Eau (DGRE) of Tunisia containing over 2000 stations. SAFRAN is a meteorological analysis system developed by Météo-France.
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...
The DEEPSTORM dataset contains daily, mensual and annual occurrences of deep moist atmospheric convection, rain and hail from 1999 to present with a resolution of 0.2°x0.2° between 60°S and 60°N. Convection, rain and hail occurrences are identified using observations from AMSU-B and MHS passivemicrowave radiometers. References : Hong G, Heygster G, Miao J, Kunzi K. 2005.

e4clim is an open-source Python software developed to integrate multiscale flexibility needs associated with Variable Renewable Energy (VRE) in the development and evaluation of regional energy mix scenarios. The software is designed to provide a flexible and extensible tool to the research and engineering community, and for educational and outreach missions. It aims at (i) evaluating and optimizing energy deployment strategies with high shares of VRE; (ii) assessing the impact of new technologies and of...
High-Tune Explorer is a suite of programs developed in the frame of the High-Tune project, supported by the ANR french research agency. The data available on the DOI is linked to a 2-part publications in Journal of Advances in Modeling Earth Systems Process-based climate model development harnessing machine learning: I. a calibration tool for parameterization improvement A major task in the development of atmospheric models is the development of parameterizations to account for processes not...
We propose here a general statistical theory to describe and generate realistic synthetic topographies of rocky exoplanetary bodies. In the solar system, we have examined the best-known bodies: the Earth, Moon, Mars and Mercury. It turns out that despite their differences, they all can be described by multifractral statistics, although with different parameters. Assuming that this property is universal, we propose here a model to simulate 2D spherical random field that mimics a rocky planetary...
This database includes the outputs (e.g Temperature, winds) of the Mars GCM (MGCM), in a common format (netcdf), obtained during the whole Martian year MY 29, at local time 3h and 15h. The runs are performed with a non-orographic gravity wave scheme activated/deactivated, as described in the paper, with the best-fit parameters listed in Table 1. The Mars Climate Database temperature retrieval dataset (version 5.2), binned in 3.75º latitude, 5.625º longitude and 5º solar longitude,...

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...
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...
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.
Nitrogen (N) and phosphorus (P) constraints on carbon (C) and energy exchanges between terrestrial biosphere and atmosphere are a major source of uncertainty regarding the drivers of the land C sink. In this study, we evaluated the performance of the global version of the land surface model ORCHIDEE-CNP (v1.2) which explicitly simulates N and P cycles on land, based on a compilation of data from remote-sensing, ground-based measurement networks and ecological databases. The sensitivity of...
