CMIP6 Climate Projections, model IPSL-CM6A-LR (IPSL)
This dataset features a selection of future climate projections variables generated by the IPSL-CM6A-LR Earth system model as part of the Coupled Model Intercomparison Project Phase 6 (CMIP6).
The data covers the future simulation period 2015–2100 and includes seven Shared Socioeconomic Pathways (SSPs):
SSP1-1.9: A very low-emission "Sustainability" scenario with the most ambitious climate policy, representing a pathway compatible with limiting global warming to 1.5°C by mid-century.
SSP1-2.6: A low-emission "Sustainability" scenario emphasizing inclusive development and environmental stewardship, representing a pathway compatible with keeping global warming below 2°C.
SSP2-4.5: A "Middle-of-the-Road" scenario representing intermediate greenhouse gas emissions and historical patterns of development, with medium challenges to mitigation and adaptation.
SSP3-7.0: A high-emission "Regional Rivalry" scenario driven by resurgent nationalism and regional conflicts, resulting in slow economic growth and high challenges to both mitigation and adaptation.
SSP4-3.4: An intermediate-low emission "Inequality" scenario characterized by a widening gap between rich and poor societies, where strict mitigation is achieved primarily through high-tech interventions by international elites.
SSP4-6.0: A medium-high emission "Inequality" scenario featuring highly stratified societies and low social cohesion, where environmental policies are fragmented and adaptation challenges are very high for vulnerable populations.
SSP5-8.5: A very high-emission "Fossil-fueled Development" scenario driven by rapid, energy-intensive global growth, representing the upper boundary of plausible future pathways.
The data is distributed in a compressed Zarr format with near-zero precision loss. It features a daily temporal resolution and is structurally optimized for high-throughput regional assessments and time-series analysis.

clt | % | for the whole atmospheric column, as seen from the surface or the top of the atmosphere. Includes both large-scale and convective cloud. |
hfls | W m-2 | The surface called "surface" means the lower boundary of the atmosphere. "Upward" indicates a vector component which is positive when directed upward (negative downward). The surface latent heat flux is the exchange of heat between the surface and the air on account of evaporation (including sublimation). In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. |
hfss | W m-2 | The surface called "surface" means the lower boundary of the atmosphere. "Upward" indicates a vector component which is positive when directed upward (negative downward). The surface sensible heat flux, also called "turbulent" heat flux, is the exchange of heat between the surface and the air by motion of air. In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. Unless indicated in the cell_methods attribute, a quantity is assumed to apply to the whole area of each horizontal grid box. Previously, the qualifier where_type was used to specify that the quantity applies only to the part of the grid box of the named type. Names containing the where_type qualifier are deprecated and newly created data should use the cell_methods attribute to indicate the horizontal area to which the quantity applies. |
hursmax | % | This is the relative humidity with respect to liquid water for T> 0 C, and with respect to ice for T<0 C. |
hursmin | % | This is the relative humidity with respect to liquid water for T> 0 C, and with respect to ice for T<0 C. |
prc | kg m-2 s-1 | at surface; includes both liquid and solid phases. |
prsn | kg m-2 s-1 | at surface; includes precipitation of all forms of water in the solid phase |
rsus | W m-2 | The surface called "surface" means the lower boundary of the atmosphere. "shortwave" means shortwave radiation. Upwelling radiation is radiation from below. It does not mean "net upward". When thought of as being incident on a surface, a radiative flux is sometimes called "irradiance". In addition, it is identical with the quantity measured by a cosine-collector light-meter and sometimes called "vector irradiance". In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. |
sfcWind | m s-1 | near-surface (usually, 10 meters) wind speed. |
sfcWindmax | m s-1 | Daily maximum near-surface (usually, 10 meters) wind speed. |
tasmax | K | maximum near-surface (usually, 2 meter) air temperature (add cell_method attribute "time: max") |
tasmin | K | minimum near-surface (usually, 2 meter) air temperature (add cell_method attribute "time: min") |
