"Re-Inventing Arecibo Observatory" Workshop

Herbert Carlson Utah State University/CASS Space Weather Center April 9-11, 2011
Hotel El Convento, Old San Juan PR


Opportunities: Climate Change
· · · · Long Term Baseline Test detailed thermal balance [radar sensitivity] Test chemical reaction rates [radar sensitivity] Test transport [radar sensitivity]


Opportunities: NEW HF ERA
HF HEATING EXPERIMENTS · · · · · · · Large Community waiting in line at the door Can do Experiments vs. simply Observe Non-Linear Plasma Physics Atomic and Molecular Physics Aeronomy Create your own Ionosphere! Practical Applications


Opportunities: Space Weather
· Mid latitude link in chain of radars · Large communities to engage [CEDAR, etc.] · Highlight unique roles for Arecibo:
­ Coupling from below ­ Gravity wave coupling from afar [& unique dual beam] ­ Topside light ion coupling/chemistry/escape

· Role in International Space Weather Program


Opportunities: Mission Support
· N A S A :
­ RBSP- Radiation Belt Storm Probe, Launch May 2012 http://science.nasa.gov/mission/rbsp

· ESA:
­ SWARM constellation- Launch July 2012 http://

· Rediscover Rockets: · Other ...


Back To "First Principles"
SENSITIVITY · Why does the Arecibo Observatory Exist?
­ Worlds Biggest Antenna and ­ Worlds Biggest Research Radar [MegaWatt-Acres!] [Don't forget: when 430 MHz Transmitter is 30% low, you have thrown away 30% of your 1000' antenna.]

· Priorities/Goals for Scientific/Engineering hires
­ Revitalize/Re-popularize single dish astronomy ­ Revitalize AO as key link in coupling with Chain of ISRs ­ 430 MHz Transmitter: Restore ~2.5MW {reach back to SRI consultants?}; AO 430 MHz Engineer daily performance

· We've heard many things AO can do for us, what can we do for it?
