The latest Arctic Report Card indicated that the Arctic ecosystems and communities are increasingly at risk due to continued warming and declining sea ice [1]. With the high spatial, spectral resolution, and the high temporal resolution over the Arctic regions, the data products derived from Joint Polar Satellite System (JPSS) provide very useful information to monitor the rapid changes of the Arctic Environment. The applications of using the JPSS imaging and sounding data products for Arctic monitoring, such as the status and the changes of the temperature, moisture, trace gases, snow and ice, as well as the outgoing longwave radiation budget will be introduced in this paper.
