Projected land allocation from IAMs is traditionally transferred to Earth System Models (ESMs) in a variety of gridded formats and spatial resolutions as inputs for simulating biophysical and biogeochemical fluxes. Existing tools for performing this translation generally require a number of manual steps which introduces error and is inefficient. Demeter makes this process seamless and repeatable by providing gridded land use and land cover change (LULCC) products derived directly from an IAM—in this case, the Global Change Assessment Model (GCAM)—in a variety of formats and resolutions commonly used by ESMs. Keywords: LULCC, land use and land cover change, First name Chris Last name Vernon Type of contact Project manager Institute / Organization Pacific Northwest National Laboratory Postal address 1 Postal address 2 Town / City Richland Postal code 99352 State Washington Country United States Email address chris.vernon@pnnl.gov Phone Fax Supported platforms Unix, Linux, Mac OS, Windows Other platform Programming language Python Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 2017 Does model development still take place?
