Interesting idea. I like it in that it is flexable (for example I
could easily print the monthly sum of precip by not dividing by a
"count", which brings me to my question. I see how you are summing
each of the variables like tmax with:
+= $tmax;
I'm not sure though how you are keeping track of the "count". In
order to print out averages, I'd have to do something like:
print $year, $doy / count, $tmax / count, $tmin / count
I don't see how $totals{$year}{$month}{count} ++; is holding the count.
