You can use FORTRAN, C, or IDL to read the data files in.  

    =============================================================

   To use FORTRAN to read the data files in for processing, please try  
the following codes.

   If you are you trying to access the chlorophyll data files, the code 
should be like this:

c	Input the Chlorophyll data
c
	integer win_xsize,win_ysize,i,ii,j,jj,k
	real*4 Chl_sat(2048,1024)
	data win_xsize/2048/,win_ysize/1024/

	open(91,file=Chl_filename,status='old',form='unformatted',
     &		access='direct',recl=2048,READONLY)
	  do j=1, win_ysize
	    jj=win_ysize-j+1
	    read(91,err=90,end=91) (Chl_sat(i,jj),i=1,win_xsize)
90	  end do
91	close(91)
	stop
	end

   If you are you trying to access the surface temperature data files, 
the code should be like this:

c		Input the Sea Surface Temperature data
c
	integer win_xsize,win_ysize,i,ii,j,jj,k
	real*4 Temp_surf(2048,1024)
	data win_xsize/2048/,win_ysize/1024/
	open(92,file=Temp_filename,status='old',form='unformatted',
     &		access='direct',recl=2048,READONLY)
	  do 90 j=1,win_ysize
	    read(92,err=90,end=92) (Temp_surf(i,j),i=1,win_xsize)
90	  end do
92	close(92)
	stop
	end

   If you are you trying to access the surface irradiance data files
with clouds from SeaWifs,  the code should be like this:

c	Input the Surface Irradiance data 
c
	integer win_xsize,win_ysize,i,ii,j,jj,k
	real*4 Irr_surf(2048,1024)
	data win_xsize/2048/,win_ysize/1024/

	open(94,file=Irr_filename,status='old',form='unformatted',
     &		access='direct',recl=2048,READONLY)
	  do 90 j=1,win_ysize
	    read(94,err=90,end=94) (Irr_surf(i,j),i=1,win_xsize)
90	  end do
94	close(94)
	stop
	end

   If you are you trying to access the calculated PAR data file,
the code should be like this:

c	Input the Surface Irradiance data 
c
	integer longitude,juliandate,i,ii,j,jj,k
	real*4 Irr_surf(1024,366)
	data longitude/1024/,juliandate/366/
	open(94,file=Irr_filename,status='old',form='unformatted',
     &		access='direct',recl=2048,READONLY)
	  do 90 j=1,juliandate
	    read(94,err=90,end=94) (Irr_surf(i,j),i=1,longitude)
90	  end do
94	close(94)
	stop
	end

   If you are you trying to access the calculated day length data file,
the code should be like this:

c	Input the day length data 
c
	integer longitude,juliandate,i,ii,j,jj,k
	real*4 day_length(1024,366)
	data longitude/1024/,juliandate/366/
	open(94,file=day_len_filename,status='old',form='unformatted',
     &		access='direct',recl=2048,READONLY)
	  do 90 j=1,juliandate
	    read(94,err=90,end=94) (day_length(i,j),i=1,longitude)
90	  end do
94	close(94)
	stop
	end

   If you are you trying to access the annual production data files, 
the code should be like this:

c	Input the Annual Production data
c
	integer win_xsize,win_ysize,i,ii,j,jj,k
	real*4 Annual_PP(2048,1024)
	data win_xsize/2048/,win_ysize/1024/

	open(94,file=PP_filename,status='old',form='unformatted',
     &		access='direct',recl=2048,READONLY)
	  do 90 j=1,win_ysize
	    read(94,err=90,end=94) (Annual_PP(i,j),i=1,win_xsize)
90	  end do
94	close(94)
	stop
	end

   If you are you trying to access the Ocean Mask data file, 
the code should be like this:

c	Input the Ocean Mask data
c
	integer win_xsize,win_ysize,i,ii,j,jj,k
	byte mask(2048,1024)
        open(99,file=MASK_file,status='old',
     &          form='unformatted',access='direct',recl=512,READONLY)
        do j=1,win_ysize
          jj=win_ysize-j+1
          read(99,err=1440,end=1450) (MASK(i,jj),i=1,win_xsize)
        end do
        goto 1450
1440    print *, 'Error in reading MASK data.'
1450    close(99)
	stop
	end

    ==============================================================

   To compile those FORTRAN code in alpha machine, you need to use the 
following command:
$ FOR/NOLIST/ALIGN=ALL/FLOAT=IEEE FILENAME.FOR

    ===============================================================

   Following is the C code. You can try to read the files in, and print 
out.

main()
{
	float data[1024][2048];
	FILE *infile; int i,j;
	infile=fopen("data.dat","r");
	(void) fread(data, sizeof(data),1,infile);
	(void) fclose(infile);
	for (i=0; i<1024; i++) {
	    for (j=0; j<2048; j++)
		printf("%8.1f",data[i][j]);
		printf("\n");
	}
}

     =============================================================

  If you use IDL, it is very easy to read the file in with the following 
code:

;   to input data from the binary file to a data array

    win_xsize=2048
    win_ysize=1024
    data_array=fltarr(win_xsize,win_ysize)

    filename=' '
    read,'Enter your file name: ',filename

    openr,1,filename
    readu,1,data_array
    close,1

;   to display the image for the data file

    window,0,color=256,xsize=win_xsize/4,ysize=win_ysize/4,title=filename
    tvscl,rebin(data_array,win_xsize/4,win_ysize/4,/sample)
    loadct,30

    end
