It was declared green-up in Fairbanks on May 17, 2022 but there’s still snow across Alaska. This RGB image taken on May 17 using VIIRS with the NOAA-20 satellite shows different types of snow. Dark blue is old or wet snow & light blue is new or dry snow. High cirrus clouds that are composed of ice are shown as cyan and water-based clouds are white. The lighter cyan shows some areas of new snow in parts of the Seward Peninsula and western north slope.
