Project: IPCC Data Distribution Centre : First Assessment Report data sets - 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. This project contains data sets from climate simulations with general circulation model. These calculations are using different forcing scenarios based on emmision scenarios for greenhouse gas and aerosols. _ This information contained in either IS92 emission scenarios (IPCC 1992) or published model studies using data from these scenarios. Six alternative IPCC scenarios (IS92a to f) were published in the 1992 Supplementary Report to the IPCC Assessment. These scenarios embodied a wide array of assumption affecting how future greenhouse gas emissions might evolve in the absence of climate policies beyond those already adoped. Model experiments, also using different forcing scenarios, were calculated at other modeling centres. Leggett, J., W.J. Pepper and R.J. Swart, 1992: Emissio ns Scenarios for IPCC: An Update. In: Climate Change 1992. The Supplementary Report to the IPCC Scientific Assessment [Houghton, J.T., B.A. Callander and S.K. Varney (eds.)], Cambridge University Press, Cambridge, UK, pp. 69-95. Summary: The 1990 UKHI equilibrium runs include an anomaly (2xCO2) run at 96x72 global resolution. From this run we received numerous parameters as a 10-year daily time series and as monthly, seasonal, and annual 10-year climatologies.
