Recap of EOSS-102Submission guidelines available at: http://submissions.eoss.org LAUNCH DATE: 8-Apr-2006 TOUCHDOWN: 09:22:13 - last airborne packet at 5285 feet altitude payload then was picked up locally by T&R team and it was reporting the surface at 4630 feet ASL. So, Touchdown was probably actually 9:23 Pre-flight Prediction and Actual Track

Experimental SystemsOur CustomerNational Oceanic and Atmospheric Administration (NOAA) EOSS has developed an excellent working relationship with NOAA. We have flown several payload systems for them from the incredibly complex (GAINS) to the elegantly simple (AirCore) GAINS Links AirCore™ note: customers are welcome to submit detailed synopses of their flights or web links to their own web sites. Payload SystemNOAA AirCore™ atmospheric sampler. Recovery Crews - There is a valve at the end of this tube with a lever. This valve was closed at 09:55 am local time during the recovery process.
Pieter Tans from NOAA attended our most recent meeting (14-Mar-06) and gave a presentation on atmospheric CO2 as well as an overview of the methodology of collecting an air sample using the AirCore™ and processing it after the flight. If you are interested visit:
I expect to receive a powerpoint file of the presentation at the EOSS meeting and I have received permission to post it along with an MP3 of Dr. Tans talk. I've received a PowerPoint file (converted to PDF below) concerning how an AirCore sample is analyzed. Like really good PowerPoint presentations, the details and all the good information are in the mind of the presenter and not really all that apparent in the PPT file. It is after all used to illustrate points being made in a presentation, not become an independent presentation of the entire subject. One of the authors will be attending the next EOSS meeting. If he gives this presentation, I'll record it and add the MP3 of that here too:
NOAA, updates detailing any changes to the experiment are most welcome as are links to NOAA pages covering this elegant device. Here is a NOAA article written about this aircore flight. Flight Systems:
Payload Configuration:Internet Gateway Stations:as seen on Findu.Com
EOSS wishes to express our sincere appreciation to the stations above who iGated the balloon APRS telemetry onto the internet. We are relying heavily on real time position information available on the net to allow the FAA controllers to have up to the minute location data to assist them in air traffic control. Redundant stations for the balloon iGating provide excellent coverage. If you are able to iGate we invite you to join the Internet Gateway Team. Contact me (webmaster@eoss.org) to be put in touch with the coordinator. By joining the team, you are giving peace of mind to the iGate coordinator for that flight. He knows you'll be there and he can rely on you. Naturally, anyone can iGate data onto the net and even if you aren't a member of the team we will welcome your contribution to the internet based tracking effort. If you callsign appears on the findu.com log, you'll be shown as a contributing station as those above are. Having more than one station covering each APRS beacon means that should a station drop out momentarily, the others can often maintain the data flow. Thanks again guys! The FAA (and EOSS) are very grateful for your assistance in this endeavor. Future I-Gaters: Check out the EOSS I-Gate page for information on how to participate and why we need you. Current I-Gate Stations: Guys, the prediction program used to determine the track of the balloon prior to flight can now output a prediction for the Rise, Closest Approach, and Set of the balloon for each of your stations. I have posted a prediction page for stations that I have been able to discover geographic coordinates. See the I-Gate prediction page for an example. The page will not be updated daily, however, it will be updated the evening prior to flight for I-gate planning purposes. I have often been asked by iGaters when they should expect to either start receiving signals (AOS) or expect to see those signals disappear (LOS). This prediction page should answer all those questions for you. Tracking and Recovery Info:
