Phenological time lapse images from ground camera MC101 in Tammela Spruce stand

This record contains phenological time lapse images from camera Tammela Spruce stand. Camera was mounted at ground view level at location 60.64598306; 23.80650111(N;E, WGS84). First set of images were taken between 31.03.2014--31.12.2016 (Version 1). Subsequent Versions extend the record with newer images, and the version number indicates the years covered by the record. Cameras were set to fix white balance, brightness automatically adjusted by camera.Image have equal resolution throughout the time series, time indicated in UTC+2. Images are taken half-hourly during fixed day-time period over the year. Gaps in time series and dark images possibly exist. More details on the camera installations and operation history can be found at 10.5281/zenodo.777952 The cameras were set up and images collected under EU Life+ (LIFE ENV/FI/000409) Monimet project, http://monimet.fmi.fi.
