In October 2007 it was discovered that the DECADAL files for Vapour Pressure (VAP) and Wet Days (WET) had been presented as each other. That is, the decadal files for VAP actually contained WET, and vice-versa. THE FULL LENGTH FILES (1901-2002) ARE UNAFFECTED BY THIS. The decadal files for VAP and WET have been taken offline. There are no plans to reinstate them. Apologies for any problems this causes. - Ian Harris, CRU 26 October 2007
