Among the many services in-situ datasets can provide to society, one of the more pressing interests currently active in the Earth Observation (EO) sector is the integration of in-situ and satellite datasets. The remote sensing community is actively using ICOS (Integrated Carbon Observation System) outputs for calibration and validation activities of satellite products. However, there are additional measurements currently excluded from the ICOS portfolio that could be beneficial for calibration and validation opportunities: for example, fraction of absorbed photosynthetic active radiation (fAPAR) and land surface temperature (LST) from thermal cameras.
An experimental setup was implemented on a subset of ICOS stations for estimating leaf area index (LAI), strictly related to fAPAR, from above- and below-canopy measurements of photosynthetic active radiation (PAR). The first longer-than-1-year datasets being available, we present some relevant preliminary results and the future direction of this activity.
NASA recently published some best practices on LST measurements for validation of satellite products. At this scope, a single thermal camera of high accuracy is deployed on a network of measuring stations. We intend to check how this setup relates to different configurations, such as different camera models, or the deployment of 3-4 lower-standard sensors looking at different angles, thus increasing the spatial resolution.
Additional points under scrutiny are: what is the heterogeneity of these variables in the eddy covariance footprint, and how can these measurements add value to the net ecosystem exchange (NEE) and its derived products? And how can the integration between satellite imagery and ground observations benefit from them?

Simone Sabbatini has a PhD in Forest Ecology, obtained in 2014 at the DIBAF department of the University of Tuscia, Viterbo, Italy. His background consists in a BSC in Forestry and Environmental Science, and a MSC in Management of Forestry Systems, both held at the University of Florence, Italy. Currently he is a Junior Researcher at the Euri-Mediterranean Center on Climate Change (CMCC), where he is involved in the activities of the Ecosystem Thematic Center (ETC), a facility of the Integrated Carbon Observatory System Research Infrastructure (ICOS-RI). At the ETC he deals with giving support to the ICOS stations concerning eddy covariance (EC), air meteorological measurements, and file submission. He is also in charge of running quality routines on EC data during the labelling time, and of caring the correct metadata ingestion of sensors by the processing routines.
