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.

Forty-eight tons (44,000 kilograms) of material from space fall onto the Earth each year. These meteoroids experience ablation and sputtering in the atmosphere, leaving behind metal and ion deposits that form thin layers in the ionosphere. Read More

A unique, high-altitude plasma cavity formed over Arecibo during an ionospheric heating campaign conducted at the observatory in June of 2019. Simultaneously, the Arecibo Incoherent Scatter Radar (ISR) collected measurements of the narrow cavity, revealing an exceptionally deep depletion of the electron density and a strong enhancement of the electron and ion temperatures.

New results from the AO Remote Optical Facility (ROF) have shown that certain wavelike perturbations in the Earth’s ionosphere are highly dependent on season in a variety of ways. For the first time, these perturbations – known as Medium Scale Traveling Ionospheric Disturbances (MSTIDs) - were conclusively shown to be modulated by the geomagnetic and solar activities.
