SITES Spectral is an infrastructure for collecting spectral data for ecosystem monitoring. Through this infrastructure, SITES can provide data for research related to climate change, carbon and greenhouse gas balances, phenology, general ecology and biodiversity and plant science.

SITES Spectral facilitates investigations of a range of processes and properties in the ecosystems, for example, productivity, light use efficiency and moisture conditions. Most research relates to climate change, carbon and greenhouse gas balances, phenology, general ecology and biodiversity, plant science, and act as a basis for upscaling and validation of remotely sensed measurements. SITES Spectral is an infrastructure with open data, all monitoring data collected by these instruments are freely available for everyone to use.

The instruments can perform measurements in forests, peatlands, mountains, lakes and agricultural areas. The equipment used is simple and robust and undergoes regular calibration. At the field research stations there are also fixed spectral instrument that records incoming and reflected solar radiation in the visible and near infrared wavelength channels.

Most of the measurements are co-located with towers that measure carbon fluxes, and managed by, for example, ICOS or FLUXNET. The equipment also includes phenological cameras and possibly future even unmanned aerial vehicles (UAVs) - as the UAV helicopters.

The participating field research stations cover a wide range of landscape characteristics and climatic gradients. Each station participate 2-4 sites of fixed multispectral sensors which covers different types of tree development stages, peatlands, mountain heats and agricultural lands. Data is collected continuously throughout the year at all stations except Tarfala due to short field season.

SITES Spectral measurements are carried out in collaboration with other infrastructures, particularly the Integrated Carbon Observation System (ICOS). These infrastructures support carbon flux measurements and a range of other environmental measurements that are used to verify, understand and cross-validate data. SITES Spectral was inspired by SpecNet with which information are exchanged. SITES Spectral also collaborate in the COST Action OPTIMISE (ES1309).

SITES NordSpec and SITES Spectral
Do you know SITES NordSpec, it was renamed in mid-October 2016 to SITES Spectral. Same content, different name!
