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.

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
