IDSS begins….

Ltg occurring in PA but not being detected by Ltgcast without MRMS over over central PA at 1852  Apr 29

MRMS ltgcast with MRMS is clearly superior to ltgcast without MRMS as the MRMS version clearly showed the ltg occurring  over central PA at 18:52

Use the planview ltg data on awips to verify ltgcast as it shows up quicker then on the dashboards.

Something is not correct…lots of ltg data showing up over our circle(KCRW) point, but it is NOT showing up on our ltgcast display board!?!? (See AWIPS plot below and match that up with the LTG cast board)

White Circle above is our IDSS point (KCRW airport)

In summary,

The MRMS version of lightningcast is superior to the non MRMS version. MRMS picked up the ltg in PA while the non MRMS version failed to pick up lightning (i.e., zero probs indicated and GLM flashes were occurring.

HOWEVER….GLM data was showing over our IDSS site as seen in the AWIPS imagery, but th eltg data was NOT plotting in the lght cast ltg boards. Something is not right and this needs to be looked at (Another way to say this is ltg cast is cheating itself….the ltg is occurring but it is not plotting the data on the ltbg boards.

I need to add that I used multiple boards at once

I wish it wasn’t so time consuming to set up things when we go into ops

Lena is very good at picking IDSS points.

Thanks to Dr Apke for going over the OCTANE in a bit more detail with me (and my group, I learned more today).
