Tim: For those of us that use the weather archives you produce and for others seeking more detailed "parameter change" data as weather systems develop I am requesting a way to directly analyze grid files, i.e. the "grid.txt" output from the objective analysis algorithm. This woul...

While trying to automate some MS Excel tasks using the objective analysis file produced each time DAWS 1.1c does an isopleth analysis I was getting non-sense results. While going bonkers checking out how I indexed arrays, thinking somewhere I was reading or writing the wrong cell of data, I discover...

Roy: Using v1.1c I have the same problem. However If the active level is set to anything but the surface my scripts work. Scripts even work when active level is set to isentropic. It appears that this is a bug. Here is my script for 500mb ht. 500 mb height (m) |HILO cont cint=30 color=80:80:140 hght...

I have requested that Tim provide a way to better utilize grid.txt files. For those who are not that familiar with grid.txt page 133 0f the user manual for DAWS explains it. In short it is a 30 x 30 grid of interpolated values of the observed data. Observations are irregularly spaced, to draw contou...

Bug Fix Version 1.1c and earlier Front drawing has a problem. It draws an extra line sometimes two, looking like a chord line between segments, then later adds the frontal symbols resulting is quite a mess. It is completely useless for drawing fronts on a map. Wish List 1. A very helpful time saver ...

Bob: For DAWS 1.1 here is the script I use for temperature advection. The zero isopleth (EQUA=0) is in bold black, warm advection isopleths (GRTN=0) are in red and cold advection isopleths (LSTN=0) are in blue. It works for v1.1. Temperature advection |CONT EQUA=0 LINE=3 COLOR=0:0:0 CONT LSTN=0 LINE...

Does anyone know in what units temperature advection is displayed in DAWS1.1 based on the sample analysis script that was provided with the program. Programs vary widely regarding this and at work our software defaults to the very akward (and unusable without conversion) 10^-4 K/sec. I ask because I...

First item: DAWS 1.1 SET COMMENT does not work for an analysis map. It does work for data plots though. Second item: Under the fronts tab in the control panel, nothing works. Clicking start new overlay generates an "access violation at address 00566342 in module 'digatmos.exe'. Read of address ...

Bob:

I sent a modified and combine version of my two posts concerning the scripting problem to Tim.

Bob I'm leaning towards a bug in the scripting module. In my example GRTN and LSTN both work individually. If three analysis functions are on one line together (EQUA=0 LSTN and GRTN) the results are a bit complex. If the first function is EQUA and the middle function is either LSTN or GRTN neither w...
