Will post updated sonde info shortly. There were two sondes dropped for wind. I confused them.

Don't really understand sondes.

[Chris_in_Tampa]

Both dropped in maximum wind band, just on opposite side of center. Both had same surface winds, but very different winds at other levels.

Do they usually drop sondes that close to each other.

[Chris_in_Tampa]

Don't really understand sondes.

As for decoding the raw text visually, I can't even do most any of it. (and I wrote the decoder, lol) Coding it was *fun* at the time though, lol. And I rewrote it since I originally wrote it too. Double the fun.

It's easier just to look at the decoded output:

http://tropicalglobe.com/recon/pacific/ ... mission=02

Very important, winds are over a very short time. I'll post a graph in a moment.

Lol. Writing the decoder but can't decode it. Gave me a chuckle

[Chris_in_Tampa]

Do they usually drop sondes that close to each other.

The following comes from the very detailed National Hurricane Operations Plan.

http://www.ofcm.gov/nhop/14/nhop14.htm



Requirements for Aircraft Reconnaissance Data

For fix pattern, when to do each:

RECCO Section 1 plus 4ddff and 9VTTT as applicable:
End points of Alpha pattern legs. When necessary with radar fix information.

Vortex Data Message (VDM):
Each fix.

Vertical Data WMO Temp Drop Code (FM37-VII) <--- sonde:
Each tasked fix at or above 850 mb. Intermediate fixes and eyewall modules as requested.

High Density Observation (HDOB):
30-sec interval



I don't recall how often they have done that. Looking at the specifications of what that means, looks like this is defined as a "Eyewall Module" pattern.



5.8. Operational Flight Patterns. This section details the operational flight patterns that
provide vortex and peripheral data on tropical and subtropical cyclones.

5.8.4. Eyewall and Outer-Wind Field Sampling Modules. These are patterns of
dropwindsonde releases designed to measure the maximum surface wind, as well as the extent of
hurricane and tropical storm force surface winds. They are meant to be flown using the operational
alpha pattern. Dropwindsonde releases in these modules are in addition to any other releases
required by Table 5-1.

5.8.4.1. Eyewall Module. While executing a standard alpha pattern to satisfy a
fix requirement, one sounding will be taken during each inbound and outbound passage through
the eyewall (except as noted below), for a total of four soundings. The releases should be made at
or just inward (within 12 km) of the flight-level radius of maximum wind (RMW). If the radar
presentation is suitable, the inner edge of the radar eyewall may be used to identify the release
point. If possible, and when resources and safety permit, two dropwindsondes, spaced less than 30
seconds apart, should be deployed on the inbound leg on the side of the storm believed to have the
highest surface winds (normally the right-hand side). In this case, the outer of the two releases
should be made at the RMW, with the second release following as soon as possible. Typically, the
eyewall module will be tasked within 48 hours of a forecasted hurricane landfall.

The highest wind sonde graphed. Near release, about 80 knots. At surface 55 knots. But inbetween, 100 knots. It tells you about the wind, temperature and dew point on the way down. I don't know much about looking at the humidity. I just look at the winds.

Lol. Writing the decoder but can't decode it. Gave me a chuckle

I started writing the recon products in 2006. I can't remember if it was 2007 or 2008 before I first wrote the dropsonde decoder. And it has been a year or more probably since I rewrote it. I never trust myself to eyeball it. I always decode it first.

I'm really impressed that you've done this all by yourself. Thank you for making it all public and free.
