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...

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...

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,...

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...

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...

The CHIMERE chemistry-transport model v2020

Laurent Menut & Laurent Menut
CHIMERE is an open source multi-scale chemistry-transport model designed to produce (i) accurate analysis of pollution episodes, (ii) daily forecasts of ozone, aerosols and other pollutants, (iii) long-term simulations (entire seasons or years) for emission control scenarios. CHIMERE runs over a range of spatial scale, from the hemispheric to the urban scale with resolutions from 1km to several degrees. CHIMERE has many different options for simulations which make it also a powerful research tool for...

2018 and 2019 ACTRIS Cloud Radar Calibration Campaign, Corner Reflectors on Masts Experiment

Felipe Toledo, Julien Delanoe, & Martial Haeffelin
This dataset contains all radar measurements used in the preparation of a new cloud radar calibration methodology, using reference reflectors mounted on masts. This data was collected during two field experiments held in 2018 and 2019 at the SIRTA atmospheric observatory, located in Palaiseau, France, in the framework of the ACTRIS-2 research and innovation program. A documented python file with the time periods used in each published retrieval is included.

ORCHIDEE-CN-P_v1.2_r5986

Daniel S. Goll
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...
