This dataset is an extraction of the Climate North America Climatic Moisture Deficit (CMD) layer for the Western Washington connectivity project. CMD is a sum of the monthly difference between reference atmosphieric evaporative demand (Eref) and precipitation.
The annual climatic moisture deficit is the sum on the monthly values [CMD(m),mm] calculated from the monthly reference evaporation [Eref(m), mm] and precipitation [P(m), mm] as CMD(m)=0 Eref(m)less than or equal to p(m) CMD(m)=Eref(m)-P(m) Eref(m) great than P(m).
We provide advanced conservation science, technology, and planning to empower our partners in solving the world’s critical ecological challenges
