Interim Issue Resolution: Air Temperature Data Bias

The extended range air temperature sensors used at SNOTEL sites in the continental U.S. calculate temperature from sensor output voltage using a linear least-squares regression algorithm. It has been determined that use of the linear least-squares regression algorithm has resulted in a data bias.

The Snow Survey and Water Supply Forecasting Program is actively working on a correction technique for this issue.
