Re: Strange map behaviour
I believe that the number of grid points DA uses in the analysis does not change when you change magnifications/scales/dimensions. So, zooming out, or changing one dimension, will result in different grid spacing. Additionally, the additional observations on the edges of the grid/display in the zoom...

Wind chill bug
Just a reminder of the continued existence of the wind chill bug documented in this thread, where the pre-2001 formula for wind chill is still being used in the 2.09 version of Digital Atmosphere.

The link to meteo.ttf from the Downloads page has very recently been updated to now have two zip files, one labeled new and one labeled old. The one labeled new appears to be the one that is installed when installing newer versions of Digital Atmosphere, and is 23 KB in size. The one labeled old is ...

You will only see the weather symbols contained with the TrueType font. There are no pressure tendency symbols as far as I am aware within meteo.ttf. Then why did I go through this troubleshooting exercise? http://www.weathergraphics.com/forum/showthread.php?t=1461 Some stations do not include curr...

Of course I'm having the same issues. Check this out... http://www.weathergraphics.com/dl/meteo.ttf and view it in Windows font viewer. I see no pressure tendency symbols on any PC. If this is the file that those symbols are supposed to be contained in, I don't see them. When I looked at this font i...

The wind chill bug, where it appears that the old (pre 2001) formula for wind chill is being used, still seems to be in the latest version. Previous documentation of this here http://www.weathergraphics.com/forum/showthread.php?t=1467 DA 2.0 and previous official version have the same output values,...

There appears to be a bad sea level pressure at KROG in NW Arkansas. It has been bad for several weeks, although the altimeter setting appears fine. I've renamed the site to KR0G (0 = zero) in the digatmos.stn file and recompiled tables so I don't have to continue QCing it to get it out of the analy...

Sorry, I had to replace the graphic with a 17Z one because of a mistake in the overlay. But I think you are right in that the program may be using the old formula. But on the topic of wind speeds and plots, at 16Z, while the plot showed 10 kts, the actual wind was 12 kts, which converts to 14 mph, b...

Wind Chill Plot/Analysis Problems In DA
Plotted a surface map in DA 1.40d this morning and overlaid wind chill (F) on it. The analyzed (and plotted in the plot options) values for wind chills were about 10-15 degrees too cold. I'm not sure if this was already a reported bug, so am posting it here. On the map below, the time is 17Z on 21 D...
