Notes and updates a) On 24-September-2007 three 30-minute averages for precipitation at the Intermediate Pine site were determined to be unrealistically high. These are the only 30-minute precipitation values that exceed 8 mm for the entire year at this site. The precipitation was set to the coincident value measured at the New Young Pine site for the following 30-minute periods: Doy Hour 335 12.0 (December 1, 2005) 335 12.5 335 13.0 Data files changed are: ip05.asc and ip05_ngf.asc b) On 27-September-2007 a problem was discovered with the ip03 air temperature from the Vaisala at the top of the tower (thanks to Dave Turner). The 2003 temperatures were too cold compared to other evidence (Sisters weather station, 30-meter HOBO, 20-meter HOBO and the sonic temperature. The Vaisala temperatures appear reasonable (nothing obviously wrong), and it is not clear what the source of the problem was. As a fix, the 30-meter HOBO temperature was substitued for the Vaisla temperature in the data files. The 30-meter Vaisala and HOBO temperatures were compared for 2004 and 2005, and for these years, they agreed quite closely. The problem appears to be isolated to 2003. Data files changed are: ip03.asc and ip03_ngf.asc c) Added notes above for, day of year = Doy + 136 for all the "0405" files. d) Variable SWC in the data files is soil moiture content from a CS615 probe and the measurement represents an average over the top 30 cm of soil. #END
