The SITES 2023 Calendar theme is “Data in Focus”. The openly available data produced within SITES and stored on the SITES Data Portal is the “golden thread” of the infrastructure, allowing users access to ecosystem data that covers diverse habitats and climate zones across geographical gradients in Sweden. Each month follow along as we highlight a unique SITES dataset.  

At Asa Research Station, located north of Växjö, the forest landscape is a mix of spruce forests, conifer mix and pine with deciduous trees. The lake Feresjön, a small (area: 0.52 km²) and oligotrophic lake, is situated in the forested landscape near the station and is part of both SITES Water and SITES AquaNet Thematic Programs. Within SITES Water, hydrological, physical, chemical and biological monitoring in Feresjön and its inlet and outlet streams is carried out. In particular, to capture the water balance, discharge measurements of the main lake inflow and outflow is taken as well as lake water level and evaporation from the lake.

An example of this data can be seen in the figure below, where continuous discharge data from 2012-2021 (calculated from stream level data and flume dimensions) at Feresjön secondary inlet stream north-west is displayed. The V-notch weir discharge station in the photo, allows continuous measurements of stream level throughout the year, even in winter when snow and ice makes the streams difficult to reach. The discharge measurements continue today and the data is made openly available on the SITES Data Portal.

This week the data retreats continue: next in line is Bolmen, SITES associated research station in Småland. The team is working on establishing workflows and a data structure for the first SITES Water related data sets coming from Lake Bolmen and to discuss future multi-station collaborations. The station lead around Sydvatten have ambitious plans to develop a high-frequency measurement program on the lake in the coming years, which is planned to follow the SITES Water layer structure.

Keep yourself posted on the SITES Data Portal for new data sets!

Joel Gräsman has been working as a Field technician during two field seasons at the Asa Station, from December 2023 he will have a full time employment at the station.

Lönnstorp Research Station, has a subject focus on cropping system dynamics within the 60 ha of conventional farmland and 18 ha of certified organic farmland. High frequency vegetation and climate data is collected from the agricultural fields and is maintained by skilled staff. The automatic weather station data includes air temperature, relative humidity, incoming shortwave radiation, air pressure, precipitation, wind speed, and soil temperature. Through SITES Spectral, a pheocamera is equipped on a mast overlooking the agricultural field (pictured below), and provides spectral vegetation data products including Green and Red Chromatic index composites and RGB composites. The graph shows sub-hourly above ground (0.2 and 1.5 m, light yellow) and below ground (-0.05 m, dark yellow) temperature data measured at the station for the first half of the year in 2021. The vegetation and climate data from Lönnstorp Research Station is openly available on the SITES Data Portal.
