I removed the surface pressure from appearing in lists in my recon system. They never sent a correction to the sonde, but I'll leave it since it has other information that might be helpful if reliable. I don't like to modify raw data other than when a mission identifier is wrong or a garbled HDOB line needs to be removed. A NOAA sonde had this issue a day or two ago but a correction was made.
