Other NOAA look fine... as mentioned, I pulled "Reports"/"NOAA Summarize Year Data" from the menu system, and all the years had rain data showing... (any other NOAA reports in mind?)
I looked through the raw data, which was a bit tedious because in 2006 I had 1 minute logging intervals--so there's a TON of rows. But I did see rainfall numbers in the raw data...
I'm thinking it's no big deal, but curious anyway...
