ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is related to the field of atmospheric measurement, and in particular, to a system that receives, stores, and transfers data indicating an atmospheric parameter
2. Statement of the Problem
Data loggers collect and store data for subsequent analysis. Some examples of this data include temperature, light intensity, and on/off status. The typical data logger is battery powered and includes a sensor, microprocessor, memory, and computer interface. The sensor measures some parameter and generates a signal indicating the measurement. Data is derived from the signal, and the microprocessor stores the data in the memory. The microprocessor may time stamp the data. Subsequently, the data is transferred from the memory to a computer through the computer interface. The computer then analyzes the data.
For atmospheric measurement, data loggers have been used to measure atmospheric parameters, such as temperature, pressure, humidity, wind, and solar radiation. Tethered balloons are used to transport data loggers to altitudes where measurements are taken. The tethered balloon is subsequently lowered, the data logger is removed, and the data is transferred to a computer for analysis.
Unfortunately, these data loggers may require too much power or may not be rugged enough for lengthy field service. The data loggers may also be too heavy and cumbersome for effective use with a tethered balloon. In addition, current data loggers can be complex to operate and may require too much engineering for some users. Current data loggers may not be off-the-shelf components, and thus, they would need to be configured to interoperate with other system components.
SUMMARY OF THE SOLUTION
The invention helps solve the above problems with an atmospheric data measurement system. The atmospheric data measurement system may be lighter and more compact than comparable data loggers. The atmospheric data measurement system may use battery power more efficiently than comparable data loggers. Also, the atmospheric data measurement system may be easier to program and use than comparable data loggers. Examples of the invention include atmospheric data measurement systems, methods of atmospheric data measurement system operation, and software products for atmospheric data measurement systems.
