tombuch 0 #3 July 6, 2005 The best I can find is surface data available at: http://www.wunderground.com/history/station/71113/2005/7/3/DailyHistory.html .Tom Buchanan Instructor Emeritus Comm Pilot MSEL,G Author: JUMP!

pchapman 279 #4 July 6, 2005 For Canada, the NavCan AWWS site (suggested by Bob.Dino) suggests one go to the Meteorological Service of Canada for historical data. e.g., http://www.climate.weatheroffice.ec.gc.ca/Welcome_e.html I've used it only a bit. It seems that only surface data is available for their reporting stations, but it does include hourly values. For temps in the atmosphere, who knows -- even the normal NavCan forecasts are for 3k, 6k, 9k, etc. feet ASL -- less detailed than what you are ideally looking for. Its always easier to get forecasts than historical data for weather. The best I can think of, is if one is doing something like reducing flight test data and need temps, make sure to get the forecast temps by calling Flight Service and then check the aircraft OAT gauge before exit...

JohnRich 4 #5 July 6, 2005 If you know the ground temp, just subtract 3.5 degrees for every 1,000 feet of altitude above that. This is a general rule of thumb, but will vary slightly depending upon degree of humidity - moist air retains warmth compared to dry air. Let's say it is 95 degrees on the ground, like here in summer time Houston, Texas. So at 13,000 feet: 95 - (13 x 3.5) = 49.5 degrees. Quote Share this post Link to post Share on other sites
freakyrat 1 #6 July 6, 2005 Jose I work in Flight Service. One of our specialists has a website that has a link to an ACCARS computer analysis of upper air soundings. Use the RUC portion and type in the four letter identifier such as CYYZ for Toronto CYUL for Montreal etc. Use the major airports 4-ltr indentifier. You can disregard the winds and dew point and isotherm data on the chart portion and use the lower portion. Here is the link, hope this helps. http://www-frd.fsl.noaa.gov/mab/soundings/ Chris Skydive Houston Quote Share this post Link to post Share on other sites

jose 0 #9 July 7, 2005 Awesome info. Unfortunately, it will not give me any information for July 3rd at 20 UTC, which would be at 2 pm PST. Damn. Quote Share this post Link to post Share on other sites
freakyrat 1 #10 July 7, 2005 Jose. I know, I think some others on this group gave you someplace to start to find the data to. Like I said the US stores this data in Asheville, NC. Canada probably has someplace that stores the data to. Probably someone at NAVCANADA knows. Chris Quote Share this post Link to post Share on other sites
