Here is a concise summary of the provided article: ## Canopy Water The article discusses the interception, throughfall, and drip of liquid and solid precipitation by the canopy. Key points: **Interception** - Liquid precipitation is intercepted by the canopy according to the fractions f_pi,liq and f_pi,ice. - These fractions depend on the exposed leaf and stem area index (L+S). **Throughfall and Drip** - Throughfall (q_thru,liq and q_thru,ice) is the precipitation that reaches the ground. - Canopy drip (q_drip,liq and q_drip,ice) occurs when the canopy water exceeds the maximum storage. **Canopy Water Update** - The canopy liquid water (W_can,liq) and snow water (W_can,sno) are updated over time. - Evaporation from the canopy (E_v^liq and E_v^ice) is partitioned based on vegetation temperature. **Ground Precipitation** - The total liquid and solid precipitation reaching the ground (q_grnd,liq and q_grnd,ice) is the sum of throughfall and drip. **Wetted/Dry Fraction** - The wetted fraction (f_wet) and dry fraction (f_dry) of the canopy are calculated. - The snow-covered fraction (f_can,sno) is used for surface albedo calculations.
