In Response To: Re: Op40 vs Bak40 (Don)
Hi Don, thanks for the quick reply. I'm an fixed wing instrument-rated private pilot, flying at or below 12,000. I noticed today when I pulled up Op40 & Bak40 for KYIP (around 10 am EDT) that they were showing quite different results for 20,000 feet & up. Op40 showed a large temp-dewpoint spread (as I recall) while Bak40 showed a much narrower one. T-D profiles at altitutdes also looked different, but not as much.
