From Dec. 1998 to Apr. 23, 1999, the actual date of the data in a Crrel data file is one day earlier than the date in the data file name. For example, met01Dec0398 actually contains data from Nov. 30, 1998. When converting Crrel's original data format to standard format, we put the correct date in the converted file name so that met01Dec0398 become 1998-11-30.dat. We also moved met01Dec0398 from 1998/met/raw/12 to 1998/met/raw/11.
