Presence/absence of new snow-fall scored from time-lapse photography collected near Toolik Field Station, Alaska, summers 2012-2016

Abstract: 

This data set describes the presence/absence of new snowfall approximated daily using time -lapse photography images near Toolik Field Station during summers from 2012 to 2016 under National Science Foundation (NSF) Office of Polar Programs ARC 0908444 (to Laura Gough), ARC 0908602 (to Natalie Boelman), and ARC 0909133 (to John Wingfield).  Additional cameras funded by other grants were also used for scoring including multiple Toolik EDC timelapse images taken at Toolik, Atigun Ridge, and Imnavait. Additional data were scored from time lapse photography taken by the Deegan and Urban labs (Office of Polar Programs #0902153 and #1417664). All data are associated with publication DOI: 10.1111/jav.01712.

Methods: 

Please see published work: DOI: 10.1111/jav.01712 for detailed methods.  Briefly, every time-lapse image was scored 0/1 with 0 indicating no snow fallen from previous image and 1 indicating new snow had fallen from previous image.  Most cameras took one image a day.  For cameras that took multiple images in one day, presence/ absence of snow was scored centered around noon (i.e. new snow present in a photo at 10:00 would be scored as new snow for the current day of year, whereas snow fallen at 14:00 would be counted as snow fallen for the subsequent day. 

Site in dataset refers to the physical location where birds were studied that these snow camera data were matched to.  Camera location in the dataset refers to the physical camera from which inferences about snowfall were made.  For more information about the cameras used in this project or to obtain original photographss, please consult the following resources:
