• After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.

    I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.

    For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.

    From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

    Sincerely, Jeff D.

For those of you who have never seen Terminal Doppler Weather Radar (TDWR) data in real time, check out this link to my work web page: http://www.cimms.ou.edu/~kscharf/w2live . Right now, there are a few interesting storms developing southwest of Norman worth taking a look at. Note the high PRF reflectivity and velocity images update every 60 seconds when storms are nearby.

The data will sometimes be available, particularly when interesting weather is happening in central Oklahoma. Producing the images takes some of my workstation's resources, though, so the web page will be not show the data most of the time.

Enjoy!
 
I love that radar... not as good at long range, but near-radar spatial and temporal resolution is awesome... You know it's cool when you see outflow as well as in the below. I think it's exciting that imagery from various radars are now available online... beit TDWR, Level II 88d, or Phased Array, all of which are available either on NSSL pages or associated pages...

Great stuff! The outflow patterns and boundaries are amazing. These lower power thresholds and higher intensity resolutions provide a great forecast capability which to me seems not fully realized by NEXRAD. Or does NIDS Level 2 provide this?
 
L2 reflectivity has the same horizontal resolution as standard NIDS, but the DBz resolution is better (intensity scale) - NIDS provides a DBz resolution of 5DBz, while L2 is .5DBz. L2 velocity has better horizontal resolution - 250m (as opposed to NIDS 1km), and better precision of velocity (knts) - 1knt (compared to NIDS velocity of 10knts).
