Control Runs

modern run

Modern_PredictedSST — A 20th-century control run for comparison against simulations with predicted sea surface temperatures (SSTs). Also called a mixed-layer ocean (Qflux) run.

modern run

Modern_SpecifiedSST — A 20th-century control run for comparison against simulations with specified sea surface temperatures.

Sensitivity Runs

sensitivity run

Doubled CO2 — A run used to quantify the GCM’s temperature response to an instantaneous doubling of carbon dioxide. The doubled CO2 level is 629.8 ppm, or twice the 1958 level. 1958 was chosen as the reference year because it was the first year represented in the Keeling Curve.


Future Climate Runs

future run

Global_Warming_01 — A global warming run that provides an example of how to apply multiple CO2 trends via EdGCM’s Setup Simulations window.

future run

IPCC_A1B — A global warming run, one of several future climate scenarios used for the IPCC’s Third and Fourth Assessment Reports. The A1B marker scenario signifies a balance across fossil fuel and non-fossil fuel sources of CO2.

future run

IPCC_A1FI — A global warming run, one of several future climate scenarios used for the IPCC’s Third and Fourth Assessment Reports. The A1FI illustrative scenario signifies an emphasis on fossil-fuel intensive sources of CO2.

future run

IPCC_A1FI_CO2 — A global warming run that focuses solely on the CO2 trend from the IPCC illustrative scenario A1FI. Of interest since the current rate of measured CO2 concentration increase is tracking the A1FI projected trend.

future run

IPCC_A2 — A global warming run, one of several future climate scenarios used for the IPCC’s Third and Fourth Assessment Reports. The A2 marker scenario assumes regionally oriented economic development, and a continuing increase in CO2 emissions.

future run

IPCC_B1 — A global warming run, one of several future climate scenarios used for the IPCC’s Third and Fourth Assessment Reports. The B1 marker scenario assumes increased use of clean and resource-efficient technologies, with an emphasis on global sustainability solutions.

future run

IPCC_B2 — A global warming run, one of several future climate scenarios used for the IPCC’s Third and Fourth Assessment Reports. The B2 marker scenario assumes less rapid and more diverse technological change than the B1 and A1 storylines, with an emphasis on local and regional solutions.

Paleoclimate Runs

paleo run

Pleistocene_21ka_S — A simulation of the Last Glacial Maximum, 21,000 years ago, with specified SSTs as reconstructed by SPECMAP.

paleo run

Pliocene_3Ma_S — A simulation of the Pliocene Warm Period, the most recent time in Earth history when CO2 levels were similar to modern, but global average temperatures were 2-3˚C warmer. Specified SSTs are provided by the U.S. Geological Survey’s PRISM2 Project.

paleo run

Paleocene_56Ma — A simulation of the Paleocene-Eocene Thermal Maximum (PETM), a time when a sudden and rapid increase in greenhouse gases led to global warming of up to 6˚C over a 20,000-year-period. Of interest for the rapidity of warming and the possible role of methane in driving the warming. Files for both predicted and specified SST simulations are included.

paleo run

Sturtian_750Ma — A Neoproterozoic “Snowball Earth” simulation for the Sturtian glacial interval, circa 750 million years ago.
