IPCC Data Distribution Centre : Fifth Assessment Report data sets

Acronym
IPCC-DDC_AR5
Name
IPCC Data Distribution Centre : Fifth Assessment Report data sets
Description
The Intergovernmental Panel on Climate Change (IPCC) has been established by WMO and UNEP to assess scientific, technical and socio-economic information, relevant for the understanding of climate change, its potential impacts and option for adaption and migration. Projection of future trends for a number of key variables are provided through this section of the DDC (http://www.ipcc-data.org/sim/gcm_monthly/AR5/).

Based on the interests and needs of model developers and data users, global scenarios for two time periods where developed:
- near-term scenarios that cover the period to about 2035; and
- long-term scenarios that cover the period to 2100 and, in a more stylized way, the period to 2300.

Four Representative Concentration Pathways RCP2.6, RCP4.5, RCP6.0 and RCP8.5 were constructed from long-term scenarios available in the published literature. These scenarios include time paths for emissions and concentrations of the full suite of greenhouse gases and aerosols and chemically active gases, as well as land use/land cover. They describe alternative technological, socioeconomic, and policy futures including both reference (without explicit climate policy intervention) and climate policy scenarios.

The data represent a subset of data sets from the distributed CMIP5 (Coupled Model Intercomparison Project Phase 5) data archive: https://pcmdi.llnl.gov/mips/cmip5/, which was collected by the ETH Zurich in support of the IPCC WGI authors. Data are available in NetCDF/CF format (https://cfconventions.org/).
