SINTEX-F CGCM Retrospective Forecasts

Data description:

This is 9-member ensemble retrospective forecasts for the period 1982-2008 using the SINTEX-F CGCM which was developed at Frontier Research Center for Global Change.

The 9 members are generated on basis of three different coupling physics (i.e., three different models in some sense) with three different initial conditions for each model. For the detailed descriptions of the coupled model and the "semi-multimodel" ensemble scheme, please refer to the five articles below.

The data is stored with GrADS format, please see "SINTEX-F.*.ctl" as examples for the data descriptions. Note: To calculate the forecast anomaly of the 9 ensembles, you need to compute each member's anomaly relative to its own climatology, respectively.

Requirement of the data usage:

Since this data set is not opened for public, we require you add Jing-Jia Luo, and Toshio Yamagata as coauthors in your publications. Please also inform us if you want to use the model data for your other research topics; this is to avoid any unnecessary conflict of interests with other users. The data should not be transfered to third party. If you do not agree, please let us know immediately.
