Graph of Freeze/Thaw Transitions

The SMAP mission will quantify the nature, extent, timing, and duration of landscape seasonal freeze/thaw transitions. SMAP freeze/thaw measurements will also contribute to understanding how ecosystems respond to and affect global environmental change, improving regional mapping, and prediction of high latitude ecosystem processes. The colored curves demonstrate how the production of carbon from an ecosystem has changed over 25 years and how it varies over a year.
