  "description": "Authors: \nJosé M. Beltrán-Abaunza \nLars Eklundh \nContributors: \nShangharsha Thapa \n\nLars Eklundh \nRelease: 1.0 - draft\n\nThe SITES Spectral Phenocam Data User Manual provides comprehensive guidance for the \ninstallation and use of phenocam data for monitoring of vegetation phenology carried out by the \nSwedish Infrastructure for Ecosystem Science (SITES). This infrastructure operates high-\nresolution digital cameras to capture temporal dynamics of vegetation at stations spanning \ndiverse Swedish ecosystems from the Arctic to temperate regions. \nThe phenocam network serves as a critical tool for understanding vegetation responses to \nclimate change, bridging the gap between ground-based observations and satellite remote \nsensing. The cameras provide continuous, automated monitoring that captures fine scale \nphenological transitions including leaf emergence, senescence, and snow dynamics. \nThe system delivers four processing levels: L0 (raw images with EXIF metadata), L1 (quality-\ncontrolled imagery), L2 (vegetation indices and ROI statistics), and L3 (daily solar-weighted \naggregates). Key metrics include Green Chromatic Coordinate (GCC), Red Chromatic Coordinate \n(RCC), and raw RGB channel values, all processed through standardized ROI (Region of Interest) \nanalysis. \nThe network employs Mobotix cameras (with some exceptions) mounted at standardized heights \nand orientations, with automated image capture every half an hour up to 2 hours during daylight. \nProcessing pipelines include solar weighting corrections (based on Lambert's cosine law), \nautomated quality assessment flagging poor visibility or extreme conditions, and SITES-\ncompliant data formatting for seamless integration with the SITES Data Portal. \n All L2 and L3 products are openly accessible through the SITES Data Portal \n(https://data.fieldsites.se/portal/), following standardized naming conventions and metadata \nschemas. The system ensures interoperability across stations through rigorous protocols for \nplatform naming, instrument IDs, and product codes. \nThe phenocam data supports research on vegetation-climate feedback, phenological trend \nanalysis, validation of satellite observations, and ecosystem productivity modelling. The high \ntemporal resolution (sub-daily to daily) fills critical gaps in understanding rapid ecosystem \nresponses to environmental changes. \nCreation Date: 2025 02 25 \nLast Modified: 2026-01-27",
