Snow is a solid form of hydrogen in earth owing to a temperature below the frozen point. It can exist in the atmosphere, land surface, and sub-surface. Compared with the most of mid-latitude where tropical cyclones are abundant, the terrestrial snow contributes to water resources such as Western US/Canada, Mediterranean, and even Tibetan Plateau in China. Recent climate change significantly has perturbed a current state and even a future trend of snow storage in earth. NASA, ultimately aimed at satellite missions including earth observation can uniquely tackle the questions of the cryospheric status of the current and the future.
My career as a hydrologist enhanced by remote sensing technologies can efficiently answer some of the important questions: how much terrestrial snowpack contribute to streamflow in a watershed scale, microwave remote sensing can retrieve the status of snowpack physical properties and how much accurately? A combination of visible-infrared and microwave frequency can accommodate each limitation to retrieve the terrestrial snowpack.
