Hello!
I ran a 48 hour rainfall summary in IRIS 6.6 this morning. While QC'ing the reports, I noticed that many of them ran low. This included ASOS, Coop and Cocorahs.
For instance,
Parkersburg ASOS PKB IRIS amount 1.78 should have been 2.04
Beckley ASOSO BKW IRIS 1.44 amount should have been 1.82
Charleston ASOS CRW IRIS 1.39 amount should have been 1.77
Elkins ASOSO EKN IRIS 1.33 amount should have been 1.45
With the Coop and Cocorahs, it appears that multiple sites had missing observations that were transmitted.
From what I can tell all RAWS stations were calculated correctly. I did not verify CWOP or AWS station data.
I was under the assumption that 6.6 would improve these type of errors?
Thanks,
Tony Edwards
