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, met01Jan0399 actually contains data from Dec. 31, 1998. When converting Crrel's original data format to standard format, we also put the correct date in the converted file name so that met01Jan0399 becomes 1998-12-31.dat
	We also moved met01Jan0399 from 1999/met/raw/01 to 1998/met/raw/12.
