Answer:
1. maps with isotherms
2. They compile data from multiple instruments.
Explanation:
The pieces of information that the National Weather Service produces are "maps with isotherms". These pieces of information depict the range of temperature and pressure occurring on the surface of the earth. Thereby providing a weather forecast that predicts the future occurrence of climate changes, which is then used to protect and enhance the lives of Americans.
Computers " compile data from multiple instruments" in producing weather forecasts. Instruments such as anemometer, wind vane, pressure sensor, thermometer, hygrometer, and rain gauge. The computer then uses specific mathematical equations to predict the weather or climate change.
