RelatedASOS/AWOS data download
The IEM maintains an ever growing archive of automated airport weather observations from around the world! These observations are typically called 'ASOS' or sometimes 'AWOS' sensors. A more generic term may be METAR data, which is a term that describes the format the data is transmitted as. If you don't get data for a request, please feel free to contact us for help. The IEM also has a one minute interval dataset for Iowa ASOS (2000-) and AWOS (1995-2011) sites. This archive simply provides the as-is collection of historical observations, very little quality control is done.
Please be patient with this page as it will take a number
of seconds to process your request and provide the result.
