Comment(by hamish):
max dbf columns somewhere 255-1028+
http://compgroups.net/comp.lang.clipper/maximum-fields-per-record-
dbf/888510
for sqlite: "`The default setting for SQLITE_MAX_COLUMN is 2000. You can
change it at compile time to values as large as 32767.`"
http://www.sqlite.org/limits.html
PgSQL, "250 - 1600 depending on column types",
http://www.postgresql.org/about/
MySQL, "There is a hard limit of 4096 columns per table, but the effective
maximum may be less for a given table."
http://dev.mysql.com/doc/refman/4.1/en/column-count-limit.html
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?
