Abstract

Techniques to calculate 1000-hour timelag fuel moistures were developed from theory of water movement in wood. The 1000-hour timelag fuel moisture is computed from mean daily temperatures and humidities and precipitation duration. Comparison of calculated and observed fuel moistures showed good agreement. Techniques to determine the seasonal starting value of the 1000-hour timelag fuel moisture are based on monthly climatological summaries. The seasonal starting value calculation was made from a least squares regression equation.
