Remote sensing instruments collect data from weather events some distance from the instrument and typically stores the data where the instrument is located and often transmits the data at defined intervals to central data centers. In 1441, King Sejong's son, Prince Munjong, invented the first standardized rain gauge.
Weather stations typically have these following instruments: Thermometer for measuring air and sea surface temperature; Barometer for measuring atmospheric pressure; Hygrometer for measuring humidity; Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period ...
An emergency medical technician (often, more simply, EMT) is a medical professional that provides emergency medical services. [1] [2] EMTs are most commonly found serving on ambulances and in fire departments in the US and Canada, as full-time and some part-time departments require their firefighters to at least be EMT certified.
