<div>Thanks for your response Dr. Huddleston,</div>
<div>I just downloaded opengrads2.0.� I have�found all the files you mention, but i have trouble following the rest. I'm new to grads and computer programming. It would help me out a lot to learn some of the basics of�using grads. For example,�</div>
<div class="im">
<div>�</div>
<div>'gfortran<a></a> -o�readsnow<a></a> readsnow.f<a></a>'</div>
</div><div>does grads�have a compiler in it or is this something i need to download seperately?�Is there a tutorial for grads basic functions that could help me learn more.</div>
<div>�</div>
<div>Also I'm not sure what "Uncomment the open(unit=93 line and edit it to read the file�wk2010<a></a> in your local path" means. </div>
<div>�</div>
<div>I know that�most grads users have far better understanding of�this kind of stuff�then me, but the grads webpage says</div>
<div>"Users at all levels are encouraged to post questions and answers on the basics of getting started".</div>
<div>�</div>
<div>Thanks,</div>

<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>

<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>
