Aerology studies the Earth’s atmosphere, using equipment such as radiosondes, weather balloons, and airplanes to measure wind, temperature, pressure, humidity, ozone, and radiation. It can aid in other atmospheric sciences and understanding the history of the Earth and other planets. Aerologists work for government agencies, private organizations, universities, and scientific instrument companies.
Aerology is the study of the Earth’s atmosphere. Interest in the Earth’s atmosphere has been a part of human life for thousands of years, with serious investigations dating back to the 1800s, although many date the specific discipline of aerology to 1944, when scientific equipment for atmospheric research was developed. This discipline is part of the larger field of atmospheric sciences, which includes topics such as meteorology and climatology.
A variety of types of equipment are used in aerology to take measurements of the Earth’s atmosphere. One of the most common is a radiosonde, a device that can take periodic measurements as it moves vertically, providing a cross-section of measurements that can extend from high in the atmosphere to ground level. Aerologists also use weather balloons and airplanes to take measurements that can aid in their work.
Issues such as wind direction and speed, temperature, air pressure and humidity level are of interest to aerologists, as are the changes in these measurements that occur as instruments ascend or descend. Aerology is also concerned with the measurement of ozone, including the use of historical data to monitor changes in the atmosphere that can be hazardous to human or animal health, and the measurement of radiation. At any one time, radiation levels in the atmosphere can fluctuate, and many nations undertake regular monitoring of radiation levels.
Understanding the Earth’s atmosphere can be used to further the cause of other atmospheric sciences and also to understand the history of the Earth. The atmosphere has not always existed in its present form, and many people are interested in exploring how the atmosphere formed, the conditions that had to be present for Earth’s atmosphere to develop the way it did, and what could potentially damage or destroy the atmosphere. Some aerologists are also interested in studying atmospheres on other planets to learn more about their formation.
Many aerologists work for government agencies, monitoring atmospheric conditions. Others may work for private organizations interested in atmospheric science, ranging from private weather forecasting companies to public advocacy organizations concerned about the ozone layer. Researchers can also find work at many universities, conducting research and training students in aerology. Other work may include working with scientific instrument companies, developing new instruments for use in aerology, and refining existing instruments to be more accurate or making changes in response to feedback from researchers in the field.
