Welcome to the February 2022 program for Palomar Amateur Radio Club.
Radiosondes are scientific instruments carried by balloons up to various levels of the atmosphere. They take weather measurements. Those results are transmitted to stations on the ground. The instruments fall back to earth after the balloon ruptures at altitude, and there is an active community of enthusiasts that go out to recover them.
We have two speakers tonight that will illuminate the wonderful world of radiosondes from two different viewpoints.
Mark Moede graduated from the University of Wisconsin - Madison with a Bachelor of Science in Meteorology in 1983. After graduation he worked in private sector meteorology until 1991, and then joined the National Weather Service in Green Bay in 1991. That's where he learned about radiosondes and launched weather balloons. In 1995, he accepted a job at the NWS office in San Diego and has been here ever since.
He is one of five "Lead Forecasters" in the San Diego office. He is the Heat Program leader with a focus on forecasting and messaging heat wave intensity and duration to the public and to Emergency Management partners in Southern California. He is also the Tsunami Program leader in his office.
Ryan Gedminas is a senior at University City High School. He started trying to track the weather balloons in 7th grade and caught his first one in 8th grade. His freshman year of high school he wrote an article for QEX about his findings and has continued to follow the developments of the community since. The last couple years he has worked as a field journalist for the Nuts and Volts and SERVO magazines in addition to working as a Production Engineering Intern for Gatekeeper Systems.
Through school and on his own he enjoys participating in competitive Swim, Waterpolo, Mountain Biking and Scuba Diving. He is planning on studying Electrical Engineering at a 4 year college in California.
He will speak about station construction, tracking, and recovery of radiosondes.
