Space & Atmospheric Sciences


Atmospheric Science is the investigation of the earth's gaseous envelope. Experiments performed at Arecibo measure upper atmosphere composition, temperature and densities in order to understand the controlling physical processes. The Arecibo Radio Telescope can measure the growth and decay of disturbances in the changing layers of charged particles which populate the region known as the ionosphere ( altitudes above 30 miles ). The "big dish" is also used to study plasma physics processes in the electrically charged regions of the earth's atmosphere. where radio waves are influenced most.

Solar Week :: March 21-23, 2018
Education March 23, 2018

March 23, 2018: The Solar Week @ AO - Special Events started last Wednesday 21st at the Science & Visitor Center (SVC) - Angel Ramos Foundation with a series of lectures offered by local scientists and guest speakers. The SVC has joined this bi-annual celebration to encourage elementary and junior students to explore the wonders of our nearest star. Also, one of the main focus for this type of events is to motivate young students to pursue higher education careers in Science, Technology, Engineering, Art, and Math (STEAM). Visitors had the chance to learn, firsthand from our speakers, what type of work scientists do at AO and how their efforts contribute to the study of the Sun and its fascinating scientific ramifications and applications.

Arecibo Call for Ionospheric Modification (HF facility)

Space & Atmospheric Jul 21, 2017

The Arecibo Observatory invites you to submit proposals for the use of the HF facility during 2018. HF experiments at Arecibo are scheduled by demand in periods of 5-7 days around new moon. Proposals should specify the associated diagnostics required: the incoherent scatter radar (ISR), active and passive optical instruments and others. Read More
