When we made the first soil moisture maps for saskatchewan in 1978 and the 1980s, it was essentially a “top-down” survey. The first step was to make rainfall maps that covered the fall recharge period, starting about mid-august. Most fall rains are system rains rather than thunder showers, so mapping was easy.
