Sea Level Pressure The ASCII files in this column(SLP) are the monthly sea level pressure (SLP) (in hPa) calculated from each individual model runs. SLP is calculated as domain averages for South East Bering Sea(54 - 60N, and 175w-160W). The units are in hectopascal (hPa). Results from six models indentified by Wang and Overland (2009) are provided here. Spatial distribution of sea ice concentration can be obtained by sending request to muyin.wang@noaa.gov or nicholas.a.bond@noaa.gov Original model output can be downloaded from PCMDI web site at http://www-pcmdi.llnl.gov/ipcc/about_ipcc.php We acknowledge the modeling groups, the Program for Climate Model Diagnosis and Intercomparison (PCMDI) and the WCRP's Working Group on Coupled Modelling (WGCM) for their roles in making available the WCRP CMIP3 multi-model dataset. Support of this dataset is provided by the Office of Science, U.S. Department of Energy."
