I think the proposed analysis dataset collection will be very helpful for your case. By the way, I did some tests on the NAM 12 km BTS and individual runs, it does look correct to me and I wonder how you come to the conclusion of: " First, during the periods prior to the latest model run, I should be getting 0 hour analyses or 3 hour forecasts from the NAM. That isn't the case, at least at times when a 0 hour analysis is available. Instead, I'm getting a 6 hour forecast (see, for example, 00, 06, 12, or 18 UTC times early in the loop when satellite and radar imagery are available." I compared the first few time steps of BTS with each individual runs, not seeing any 6 hour forecast in the BTS. Do I miss something?
