<p>Hello All,<br>
I'm doing snow Research and looking for a program to covert the climate prediction center (CPC) Northern Hemosphere raw weekly snow data (in 1's and 0's) into a useable number. I don't have much coding experience or computer science background, so i'm not sure
how to covert the data myself, or what program to use. Also I don't have any fortran compiler. The CPC does covert the data into a nice table format, but they don't keep it up todate. Their website is
<a href="http://www.cpc.ncep.noaa.gov/data/snow/" target="_blank">http://www.cpc.ncep.noaa.gov/data/snow/</a>. On their website they have a link to grads.<br>
<br>
The program they give for reading weekly 89*89 snow data is<br>
<br>
PROGRAM AREA<br>
C*********************************************************************<br>
C<br>
C THIS PROGRAM SIMPLY READS IN THE SNOW DATA AND<br>

C<br>
199 CONTINUE<br>
10 CONTINUE<br>
999 STOP<br>
END</p>
<p>I'm using windows 7 64bit operating system. My question is how do i use grads to view the snow data or is there a fortran compiler the above program will work on that i should use instead?<br>
Thanks,<br>
Bob R Duke</p>
