Daily Summary Observations, First Order - United States

This collection consists of data that has been quality controlled through both an automated and manual QC processes. The dataset consisted of summary of the day data from approximately 500 First Order stations (primarily major airports) in the U.S. and its possessions. Included variables are: daily summaries of hourly data for temperature, precipitation, pressure, observed weather, and wind speed and direction. The primary source of this information is from the Automated Surface Observation System (ASOS), however other collections are also included, such as SRRS, keyed data, and others -- see documentation for a complete list. Data were incorporated into the GHCN-Daily dataset as of 2013.
