Article Title: Identifying Canopy Snow in Subalpine Forests: A Comparative Study of Methods
doi: 10.1029/2023wr036996
Figure Lengend Snippet: Figure 9. Binarized snow on canopy from the (a) human labeling of images from the niwot3 Phenocam, (b) thresholding method applied to the niwot3 Phenocam images, (c) human labeling of images from the niwot5 Phenocam, and (d) thresholding method applied to the niwot5 Phenocam images during January 2019. The grayed‐out sections indicate times when Phenocam images could not be analyzed due to light conditions (e.g., sunrise, sunset, or nighttime) or were unavailable (2019‐01‐16 to 2019‐01‐19). The temporal resolutions of the niwot3 and niwot5 Phenocams are 30 and 15 min, respectively. The black points indicate precipitation measured at 30‐min intervals from the nearby U.S. Climate Reference Network site when air temperatures were below 0°C (Figure 1).
