GPS: making sense of Earth’s atmosphere

Weather observation techniques have improved and there have been technological advancements in predicting the weather in recent times. Despite this major scientific and technical progress, many challenges remain, hence limiting meaningful forecasts more than 5~6 days in advance. Given that biologica...

description Weather observation techniques have improved and there have been technological advancements in predicting the weather in recent times.
