*** 00readmeiharc *** cursory documentation of archive of GOES Sounder 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] - - - - - - - - - - - - - - - - - - - - - - - cd 02079 ls -l (... showing the 12 through 14 UTC window ...)
