Dear Hoop,
Thank you so much for your prompt reply. I did a mistake when I copied to
gmail. But the message was same.  ncdump gives the following

ga-> !ncdump -h  /home/data/pre/1995/01/pre_1995_01_01_00.nc
netcdf pre_1995_01_01_00.nc {
dimensions:
    LON = 3223 ;
    LAT = 4943 ;
    TIME = 1 ;
variables:
    double LON(LON) ;
        LON:units = "degrees_east" ;
        LON:long_name = "Longitude" ;
    double LAT(LAT) ;
        LAT:units = "degrees_north" ;
        LAT:long_name = "Latitude" ;
    double TIME(TIME) ;
        TIME:units = "seconds since 1970-01-01 00:00:00 +0:00" ;
        TIME:long_name = "Time" ;
    short PRE(TIME, LAT, LON) ;
        PRE:long_name = "60-minutes precipitation" ;
        PRE:units = "1e-3 meter" ;
        PRE:missing_value = -32768s ;
        PRE:scale_factor = 0.01f ;
        PRE:add_offset = 0.f ;
