Data Usage Notes
July 2003: MSLET Missing for ETA 218 Forecast Hour 09
Messages from 09-hour forecast data for parameter MSLET in the ETA 218 grid are corrupt for all the cycles. We are unable to plot this data using GrADS or extract the data using GDS.
Also, the 09-hour forecast data for parameter MSLET in the ETA 218 grid is not being transmitted as a separate message. It is appended to the message for the forecast hour 03 data. It should arrive as bulletin ZPBE89*, but it arrives within bulletin ZPBB89*.
