File parameters for Alaska Temperature Range data. Map: Projection Albers Equal-Area Conic First standard parallel 55 00 00 N Second standard parallel 65 00 00 N Longitude of central meridian 154 00 00 W Latitude of origin 50 00 00 N False easting 0 False northing 0 Spheroid parameters: Clarke 1866 Units of measure Meters Cell size 1,000 meters Center of pixel (1,1) ( -997000, 2422000) Number of lines 1,992 Number of samples 2,512 Header file None Header record None Data depth Byte (8 bits) Number of channels 1 Albers meters for minimum bounding rectangle (X, Y): Upper Left (-977500 2422500) Upper Right (1534500 2422500) Lower Left (-977500 430500) Lower Right (1534500 430500) Geographic degrees, minutes, and seconds: Upper Left (179 51' 52" W 70 4' 39" N) Upper Right (115 59' 22" W 67 41' 51" N) Lower Left (168 36' 9" E 52 55' 0" N) Lower Right (131 35' 27" W 51 31' 53" N) Cell values: The value in each cell is the range in temperatures for the month at that x,y location. It is a continuous variable in units (increments) of 1/10th of a Degree Centigrade (ie. a value of 100 = a range of 10.0 degrees C). The range in temperature data can be used to calculate average minimum and average maximum temperatures, using: min = meantemp-(range/2). The temperature range data was calculated using the station records data from NCDC's Global Historical Climatological Network V2 data, by Wolfgang Cramer. Ocean and missing data have values of zero.
