NERC EDS Environmental Information Data Centre 10.5285/8e30cead-700c-425c-841f-74c70659666a This dataset includes the dates and/or duration of all the environmental and phenological events that could be derived from a series of photographs taken by a fixed-point repeat camera system at the UK Environmental Change Network (ECN) site in the Cairngorms National Park, Scotland. The data covers the timing of permanent winter snow fall and subsequent spring melt on northern and eastern facing hill slopes between 2002 and 2019, as well as invertebrate (spittlebug spittlemass) and plant (heather flowering, scots pine leaf flushing) phenological events between 2010 and 2019. Three photographs were taken on a daily basis to maximise the chances of cloud free images, with the clearest image used for analysis. Event detection was generally achieved using manual assessment, but heather flowering showed a high degree of subjectivity, and so an automated pixel colour counting method was used to determine the peak flowering season. This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

Where melt day occurred between two weekly images, the day of melt was subjectively estimated based on size of remnant patches in the final image containing snow; and would carry an error of ±3-4 days. The camera system was upgraded in 2010. Phenological data could not be established on the earlier camera system due to image quality issues in the foreground. However, the change in camera had no impact on the detection of snow events pre- and post- upgrade, so the full time-series is useable. Data was checked for obvious errors where values might have fallen outside of an expected range. As most of this dataset involved manual assessment, the event detection date is as perceived by that surveyor. A different surveyor might find a slightly different date for some variables. Surveyor differences have not been assessed.
