How can I find historical daily minimum temperatures with associated atmospheric pressure for airport reporting stations?

To find international daily data try GLOBALSOD

http://ingrid.ldeo.columbia.edu/SOURCES/.NOAA/.NCDC/.DAILY/.GLOBALSOD/ .

However our international daily data are available from only a 6-year period (1994-1999). If you are looking for daily data within the U.S. only, see FSOD:

http://ingrid.ldeo.columbia.edu/SOURCES/.NOAA/.NCDC/.DAILY/.FSOD/

Our U.S. data extend over a much longer period.

In either dataset, you can click on "List of stations in current view" under the map and then search for a particular station name, or you can go through the list and select multiple stations using the toggle boxes next to each name. You can also zoom in on an area of interest with the map interface first to reduce the number of stations that come up on the list.

The available variables include daily minimum temperature and daily average pressure.
