A station name is a three letter identifier for an airport or a weather station. One example is "roc" for Rochester, New York. If you want a state wide search, enter "@NY", where the NY is a two letter ID of a state (NY is New York).
Raw Partial Full
A raw decode gives the observations in SA format. If you are not familiar with this format (most pilots and meteorologists are) then use a partial or full decode option to turn the observations into readable english text
