Phenological time lapse images from ground camera MC126 in Lammi Birch stand

This record contains phenological time lapse images from camera Lammi Birch stand. Camera was mounted at ground view level at location 61.05211; 25.04180(N;E, WGS84). First set of images were taken between 11.12.2015--31.12.2016 (Version 1). Subsequent Versions extend the record with newer images, and the version number indicates the years covered by the record.<br> 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.<br> More details on the camera installations and operation history can be found at doi 10.5281/zenodo.777952<br> The cameras were set up and images collected under EU Life+ (LIFE ENV/FI/000409) Monimet project, http://monimet.fmi.fi.<br> For further information contact [e-mail]本数据集包含来自Lammi桦木林分观测相机的物候延时摄影图像。该相机架设于地面观测高度，布设坐标为北纬61.05211、东经25.04180，采用WGS84坐标系。首批图像采集于2015年12月11日至2016年12月31日期间，对应版本1。后续版本通过新增图像对数据集进行扩充，版本编号可表明数据集所覆盖的年份区间。 相机设置为固定白平衡，亮度由相机自动调节；全时序图像分辨率保持一致，时间戳采用UTC+2时区。全年于固定日间时段内每半小时采集一次图像，时序序列中可能存在数据空缺与过暗图像。 有关相机安装与运行历史的详细信息可查阅DOI：10.5281/zenodo.777952。 本数据集的相机架设与图像采集工作依托欧盟Life+（LIFE ENV/FI/000409）Monimet项目开展，项目官网为http://monimet.fmi.fi。 如需获取更多相关信息，请联系[e-mail]
