Comment(by hamish):

 max dbf columns somewhere 255-1028+

 for sqlite: "`The default setting for SQLITE_MAX_COLUMN is 2000. You can
 change it at compile time to values as large as 32767.`"

 PgSQL, "250 - 1600 depending on column types",

 MySQL, "There is a hard limit of 4096 columns per table, but the effective
 maximum may be less for a given table."

 how many met stations? if less than the number of time records maybe
 consider to invert the array and organize data by time instead of
 position? or split up into multiple files by e.g. year?
