Title: ARCMIP Atmospheric Initial and Boundary Conditions Contact: Elizabeth Cassano University of Colorado Campus Box 216 Boulder, CO. 80309-0216 Phone: 303-735-5808 Fax: 303-492-1149 E-Mail: ecassano@terra.colorado.edu Description: The data are ECMWF analysis data. The data cover the SHEBA year (September 1, 1997 - September 30, 1998), 4x day. There are 13 files (yymm.hdf), each containing the latitude and longitude data, and the atmospheric variables. The files contain in this order: latitude, longitude, temperature (K), specific humidity (kg/kg), u-component of the wind (m/s), v-component of the wind (m/s), geopotential height (m), surface geopotential height (m), and surface pressure (Pa). The data format is hdf, and the dimensions of the data are 180x31x31 (except for the surface variables of course, which are 180x31). The latitudes and longitudes of the data are as follows: LATITUDE: 90.00 88.00 86.00 84.00 82.00 80.00 78.00 76.00 74.00 72.00 70.00 68.00 66.00 64.00 62.00 60.00 58.00 56.00 54.00 52.00 50.00 48.00 46.00 44.00 42.00 40.00 38.00 36.00 34.00 32.00 30.00 LONGITUDE: -180.00 -178.00 -176.00 -174.00 -172.00 -170.00 -168.00 -166.00 -164.00 -162.00 -160.00 -158.00 -156.00 -154.00 -152.00 -150.00 -148.00 -146.00 -144.00 -142.00 -140.00 -138.00 -136.00 -134.00 -132.00 -130.00 -128.00 -126.00 -124.00 -122.00 -120.00 -118.00 -116.00 -114.00 -112.00 -110.00 -108.00 -106.00 -104.00 -102.00 -100.00 -98.00 -96.00 -94.00 -92.00 -90.00 -88.00 -86.00 -84.00 -82.00 -80.00 -78.00 -76.00 -74.00 -72.00 -70.00 -68.00 -66.00 -64.00 -62.00 -60.00 -58.00 -56.00 -54.00 -52.00 -50.00 -48.00 -46.00 -44.00 -42.00 -40.00 -38.00 -36.00 -34.00 -32.00 -30.00 -28.00 -26.00 -24.00 -22.00 -20.00 -18.00 -16.00 -14.00 -12.00 -10.00 -8.00 -6.00 -4.00 -2.00 0.00 2.00 4.00 6.00 8.00 10.00 12.00 14.00 16.00 18.00 20.00 22.00 24.00 26.00 28.00 30.00 32.00 34.00 36.00 38.00 40.00 42.00 44.00 46.00 48.00 50.00 52.00 54.00 56.00 58.00 60.00 62.00 64.00 66.00 68.00 70.00 72.00 74.00 76.00 78.00 80.00 82.00 84.00 86.00 88.00 90.00 92.00 94.00 96.00 98.00 100.00 102.00 104.00 106.00 108.00 110.00 112.00 114.00 116.00 118.00 120.00 122.00 124.00 126.00 128.00 130.00 132.00 134.00 136.00 138.00 140.00 142.00 144.00 146.00 148.00 150.00 152.00 154.00 156.00 158.00 160.00 162.00 164.00 166.00 168.00 170.00 172.00 174.00 176.00 178.00 If there are any questions, please contact Liz Cassano at .
