weather analysis software - GRLevelX
« on: 03 March 2007, 08:48:25 AM »
Hi all, I am familiar with the application of the Baron/WxWorx package for chasing in the US - it was a great addition last year, but I was trying to find out more about the GRLevelX software packages and how they work.  Some research on the product hasnt really answered my questions.  The 3D rendering of storm structure looks fantastic but is it a REALTIME product such as the Baron (it is close to realtime) or not and is it accurate data?  Has anyone used this product while chasing in the USA?

here's a link:

I only looked at this briefly last year around the time we go WxWorx, so will stand corrected.

The main advantage with Wxworx (mobile threatnet) is coverage (ie satellite) - (also, there have been some update to the software this year I believe?). The actual output that you can get is, however, pretty basic. Also, the hail algorithms and 'shear markers' are probably not all that great (ie your 'twisting storms' haha) as you might have found out.  That said it is excellent in that it allows you to see what is going on to look at base reflectivity and identify hook echos etc and not worry to much about loosing your signal anywhere.

GRLevelX (Level 2 and Level 3, see below) relies on you being confident that you will be able to get online wherever you happen to be. This is becoming less of a problem (both coverage and costs) on the plains with each passing year. I might be wrong but I really dont see a massive advantage of full Level 2 as opposed to what you get with the Baron.

On the other hand, with GRLevel3 you will be getting the full suite of data including some excellent forecasting tools. Anyone interested in understanding the differences between Nexrad level II data (eg as captured by GRLevel2) and level 3 (GRLevel3) go to:

Im pretty sure quite a few US chasers use GRLevelX so ST should have some user experiences.
