Snow Water Equivalent (AMSR-E)

The Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E) distributes daily, weekly, and monthly products which includes snow water equivalent. Note: "On 04 October 2011, the AMSR-E instrument on board the Aqua satellite stopped producing data due to a problem with the rotation of its antenna."

Key Limitations:

  • AMSR-E snow water equivalent (SWE) is biased low
