However, atmospheric pressure varies with time, position, and altitude. Pressure generally decreases with altitude. It also can drop rapidly just before a storm blows in. Pressure also depends on temperature, so I expect there is a seasonal variaton (although I've never looked at that sort of data). You might be able to find, for example, a table of observed atmospheric pressure at 5am every day at a specific weather station at an airport in the city. I'm not sure how that would help on a test. If you are investigating seasonal averages, you could try to get daily data an average it yourself. In the US, the primary sources for weather data are airports and NOAA (www.noaa.gov) sponsored weather stations (which categories sometimes overlap). I don't know what the situation is in Brazil. If you can't find anything on a web search, you could try calling the airport. -- Erik Reuter http://www.erikreuter.net/ _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
