Phenological Photographs of vegetation and river in Chokurdakh, northeastern Siberia

The dataset is phenological photographs of forested tundra and tributary of Indigirka river from 2013 to 2017 near Chokurdakh, Repbulic of Sakha, Russia. Time-lapse digital cameras captured the vegetation growth period and the spring flush of river water at three observation sites (Boydom, Kodac, Verkhny-Khatistakh). The time intervals were 1-4 or 24 hours. This dataset is useful (i) to detect the onset and offset of the growing season and the ice melt timing and water cover periods in wetlands and riversides, (ii) to assess the ecosystem response to climate factors, and (iii) to validate satellite remote sensing in the circumarctic region.

该数据集包含2013至2017年期间，俄罗斯萨哈共和国乔库尔达赫附近森林苔原（forested tundra）及因迪吉尔卡河支流的物候照片（phenological photographs）。延时数码相机在Boydom、Kodac和Verkhny-Khatistakh三个观测点，捕捉了植被生长周期及河流水体的春季汛情（spring flush of river water）。时间间隔为1-4小时或24小时。该数据集的应用价值体现在以下三个方面：（i）检测生长季的开始与结束时间，以及湿地和河岸的融冰时间与覆水期；（ii）评估生态系统对气候因子的响应；（iii）验证环北极地区的卫星遥感数据。
