Studying global change in a holistic manner requires the understanding of evolutionary processes in the environment from the past, as well as providing the predictive power to forecast and model changes into the future. The Nasa Earth Exchange (NEX) platform provides Global Daily Downscaled Projections (GDDP) data for future climate models. These models were developed in support of the Intergovernmental Panel on Climage Change (IPCC)'s assessment of several models of future climate predictions based on different scenarios of CO2 emissions. The Ecoengine will incorporate these rasters as base layers for the Explore interface in the near future. The full data set can be downloaded here.
Yugaroshi Mondal, a member of the Ecoengine team, is assiting on the development of high-resolution climate models from the Last Glacial Maximum (LGM) and mid-Holocene. These data will reconstruct temperature and precipitation profiles over the continental United States, and used to compute bioclimatic variables for the purpose of species distribution modeling. More information on the project can be viewed here on figshare.
