The Micromet System provides the Edwards Rocket Propulsion Laboratories meteorologist with a complete weather status of the entire area for use in making operational decisions. Sixty-four sensors are mounted on sixteen towers which are located to optimally cover the test range. The data from all the sensors is automatically gathered under computer control at the rate of two samples per second per sensor. The data is processed by the computer and out-putted in several different but complementary ways for use by the meteorologist. These include a pictorial display map, a data logger, typewritten messages and punched cards. One of the most useful messages is the solution of dispersion prediction equations relating to the dispersion probability of gas clouds resulting from the rocket motor test firings. The dispersion prediction calculations are quite involved, yet they are done routinely by the computer. It would be impossible to do them manually in the time available and further, the undesirable factor of human error is not present. Another feature of Micromet is an automatic computer controlled calibration system which calibrates the system once each 30 minutes. Data scaling factors are obtained from this which maintain the data accuracy. Also, maintenance messages result which are automatically typed out for any sensors that are out of tolerance by more than a predetermined amount. The system operates 24 hours a day, 365 days a year without an attendant except for scheduled maintenance periods. Author
