The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL cdm_data_type String Grid
attribute NC_GLOBAL comment String GFDL experiment name = c360_hiram_H3. Downscaling method = Asynchronous Regional Regression Model (ARRM) of Katharine Hayhoe vMarch2012. CMIP5 experiment name = AMIP (r2i1p1). Big Brother experimental design: (a) Original GFDL-HIRAM-C360 model output interpolated to coarser CM2.1 atmospheric grid. (b) Training of downscaling performed using 'leave N out' approach. (c) Coarsened output from left-out time period input to downscaling equations derived in (b) to yield estimates of original C360 model results for cross validation.

attribute NC_GLOBAL note String CMIP5 experiment name = AMIP (r2i1p1). The high-resolution GCM was run in AMIP mode with SST and sea ice concentration determined from the HadISST1 data set ( The sea-ice model assumes that each grid point is either fully ice-covered or ice-free and also assumes a uniform ice thickness of 2 meters. This realization was started on 1976 January 1 from initial conditions taken at 1977 January 1 from the GFDL-HIRAM-C360 AMIP experiment (r2i1p1). The first three years of this integration (1976-1978) have not been published.
