NOAA Historical Observing Metadata Repository API - How To

The service provides metadata describing stations maintained by the U.S. National Oceanic and Atmospheric Administration (NOAA) for monitoring weather conditions. It does not provide measurements of weather logged by the stations, rather it gives station locations and describes their surrounding environments. Location is specified as two-letter codes for U.S. state or Canadian province and latitude/longitude pair. Additional conditions noted include elevation, nearby rivers or lakes, etc. API methods support retrieval of descriptive metadata about a weather station, either by NOAA ID value or name, with dates when conditions were assessed. Methods also retrieve stations within a specified state or country and descriptive data recorded during particular date ranges.
