Dropped from aircraft, once an AXBT is in the water this expendable instrument drops a sensor deep into the water column measuring water temperature at various depths.
Reconnaissance Archive Description
Recon data on our site is raw. The raw observations will contain errors at times. The dates above represent the period over which reconnaissance took place, not the duration of the storm. The first date is the date of the first mission and the last date is the date of the last mission. All other observations noted on this archive page come solely from vortex messages, if available. Since this data is more likely to have been reviewed, we use it rather than using any other products on this summary page. It will still sometimes be erroneous. Additionally, our site will not always decode the most significant observations. If that occurs, they will not be reflected here. The highest flight level wind will usually be from the highest flight level wind remark in the remarks section, though it may come from item F, which is where the maximum inbound flight level wind is reported.
