DPI data (gif files) for IHOP 2002
Data are ordered by date; each day's products are contained in its own
directory, named in the "yyddd" format (day of the year).
Typical naming convention example:
ihpw.02079.1146.gif
ih - for IHOP
pw - parameter abbreviation (here it's precipitable water)
.02079 - day of the year [yyddd - from (20)02, the 79th day
.1146 - time UTC [hhmm] aka 20 Mar 2002]

Simple converter for calendar day to day-of-year (non leap year)
"offset" array for each month:
0 1 -1 | Jan(1) Feb(2) Mar(3)
0 0 1 | Apr(4) May(5) Jun(6)
1 2 3 | Jul(7) Aug(8) Sep(9)
3 4 4 | Oct(10) Nov(11) Dec(12)
[(month-of-year - 1) * 30] + day-of-month + offset = day-of-year
Example: 20 March
[(3 - 1) * 30] + 20 + (-1) = 79
