Experience indicates that although pressure pillows provide useful accuracy for seasonal measurements of snow‐water equivalent, there may be problems in providing accurate measurements of the variation in melt rates for short periods of time. Temperature and barometric variations affect the accuracy of measurements of melt rates but are predictable or small. However, unexplained diurnal variations were found to be significant during the snowmelt period. These diurnal fluctuations are large enough to cause significant error in measurements of the daily melt but not in the measurements of the seasonal accumulation. (Key words: Snow; instruments)
