An example of the full range of the instruments used in the ASOS Ensemble. We begin with the silence of absent data, followed by a demonstration of the wind instrument. Next is the three instruments used for the heat index (or "feels like" temperature). They cover periods of increasing air temperature and heat index, increasing air temperature with constant heat index, and constant air temperature with increasing heat index. Afterwards we hear 24 hours of precipitation, followed by a silly tune.
