Summary

This data package includes 17,014 pairs of raster geotiffs. Each pair is made up of two geotiff rasters derived from historical observations from Landsat satellites (04-09) over the Yukon, Kuskokwim, and Tanana rivers in Alaska. One raster reports estimated mid-day water surface temperature (ST) in degrees Celsius (deg_Cc). The second raster reports the surface temperature quality assessment (sST_QA_c) and provides the ST product uncertainty (also in degrees). The period of observation is May through October for the years 1984-2022.

Purpose

Our project sought to extract spatially explicit water temperature estimates for three of Alaska's large rivers - the Yukon River, Tanana River, and Kuskokwim River, utilizing the Landsat Analysis Ready Data (ARD) Surface Temperature product. Presently, ARD ST data are available for download on a scene-by-scene basis and it is up to the end user to further extract relevant information from each scene. This can be a time-consuming process that requires an advanced familiarity with the ST product. We extracted and compiled only ST values that corresponded to cloud-free water surfaces of the Yukon, Tanana, and Kuskokwim rivers during the ice-free season between 1984 and 2022. These data provide estimates of water temperature for vast portions of Alaska rivers where water temperature data have not been previously collected.
