You can get much of the necessary data if you have a date/time and location from the timeslip. Just go here - http://www.wunderground.com/history/airpor...eq_statename=NA - and look up the (closest) location and time to get the data. Since the baro. reading is "sea level" you will not need an elevation, just input the data into a calculator like this - http://users.erols.com/srweiss/calcda.htm - and you will have a reasonable estimate of density altitude.
Of course every track SHOULD put this info on the timeslip, but it's not a perfect world.
