Hi,
I'm trying to read TRMM precipitation data from a binary file that I
donwloaded from NASA's web site. The information I have about the file
is:
-----
Data are in 4-byte binary float from a SUN system (big-endian).
units are mm/hr, mm/6hr, mm/day, etc.
coverage is:
60 to -60 lat
0 to 360 long
at:
.25 x .25 deg resolution
for:
480 rows x 1440 cols
data is stored in C style row centric format.
The first value is centered at
59.875,.125
the second value at
59.875,.375
last 2 values are centered at:
-59.875,359.625 &
-59.875,359.875
sample matlab code:
function om = loadbfn(fn,dim,sz)
% loadbfn -- loads a binary file fn of dim
% ([nrows ncols]) of sz 'float','int', etc.
%
% by DKB on 2/5/96
%
if(nargin < 3)
sz = 'float32';
end
f = fopen(fn,'r','b');
if(nargout > 0)
om = fread(f,flipud(dim(:))',sz)';
end
fclose(f);
-----
My python code is:
>>> import uu
>>> infile =
>>> 'F:\\Hanlie\\UCT\\M.Sc\\Data\\PERSIANN\\2009_10_PERS6hr\\ms6s4_6h0927400.bin'
>>> outfile =
>>> 'F:\\Hanlie\\UCT\\M.Sc\\Data\\PERSIANN\\2009_10_PERS6hr\\ms6s4_6h0927400.txt'
>>> uu.decode(infile,outfile)
Which produces the error:
Traceback (most recent call last):
File "<pyshell#23>", line 1, in <module>
uu.decode(infile,outfile)
File "F:\Python26\lib\uu.py", line 98, in decode
raise Error('No valid begin line found in input file')
Error: No valid begin line found in input file
Can someone perhaps help me?
Thanks
Hanlie
