Precipitation Version 1 in directry ver1



1. Data files:

   (1). 1985-1996   

   (2). yy.sum: annual total precipitation (mm)

   (3). yymm.sum: monthly total precipitation (mm)

   (4). yy1-yy2.mean: annual mean precipitation from yy1 to yy2 

(mm)

   (5). latitude and longitude data of grids:

        lat.dat: latitude data of grids

        lon.dat: longitude data of grids

   (6). topo.dat: terrain data of Greenland ( meter ) 



2.  Model parameters: 

   (1). The number of grid points is 67x69

        x direction: 67;   y direction: 69

   (2). The grid space = 50km

   (3). Central latitude and longitud: ( 71.5N,-40W)

        Note: for longitude dat:  

           0 - 180E, the numbers is positive  

           0 - 180W, the numbers is negative
