NASA Explorers | The Snow Below | | S1 EP 2 |

Snow is one part of the cryosphere that many of us have actually encountered, but it also plays a crucial role in regulating Earth’s climate. Through decades of remote sensing, NASA has kept a close eye on the ebb and flow of snow cover. #NASAExplorers also venture into the field at the far reaches of Earth to study snow, a critical resource for the millions of people who rely on it for drinking water.
