In this animation, the first image shows an agricultural region in Idaho on August 14, 2000, captured in the visible spectrum. The round, green circles are irrigated farm fields. The second image, using Landsat's thermal band, depicts cooler and warmer areas. Irrigated fields appear cooler because evapotranspiring water absorbs energy and cools the fields. The thermal image dissolves into a map of evapotranspiration, created using the METRIC tool.

This thermal band image shows the same agricultural region in Idaho on the same day. The thermal band - Landsat's band 6 - captures data on land surface temperature. As agricultural growers irrigate farm fields, water evaporating from the soil and transpiring from the plants' leaves absorbs energy and cools the fields.
