Hyltemossa is located a few kilometers south of Perstorp, in northwestern Scania (Skåne, 56°06′N, 13°25′E, 115 m asl).
The site Hyltemossa was established in 2014 in a managed spruce forest in southern Sweden. The site hosts a combined Atmosphere and Ecosystem station. The research site also hosts a stations for the national infrastructure ACTRIS Sweden.
Hyltemossa Research station is one of the observational platforms in the ATMO ACCESS/ project giving access to researchers through TNA. Follow the weblink to read more about the rules, how to apply and access the online formular.

Data from Hyltemossa can be downloaded from the ICOS Carbon Portal. ICOS Level2 data from the Atmosphere Station HTM (GHG concentrations, air temperature, wind). ICOS Level2 data from the Ecosystem Station SE-Htm (flux data, meteorological data, soil meteorological variables, ancillary data). ICOS Level 1 Near Realtime Data
Data is collected at 4 continuous plots around the main measurement tower.
Geology and Soil
The underlying bedrock at the site, found in a depth from 20 - 50 m, is composed mainly from acidic intrusion rock such as Granite with some limited occurrence of a younger ultrabasic rock such as Gabbro.
Quaternary deposits at the center of Hyltemossa Site are dominated by sandy till surrounded by glaciofluvial sediments. Occasionally fen peat and to a small extend crystalline rock and boulders can be found.
Soil at the site is classified as Cambisol with a shallow organic horizon, a transition to Podsol can be found in certain areas. Stones in various sizes are found frequently and in some areas influence of groundwater is obvious in 1 m depth.
The site around the tower is dominated by Norway spruce (Picea abies) with a small fraction of birch trees (Betula sp.) and single occurrence of Scots pine (Pinus sylvestris). Understorey vegetation is sparse. The forest floor is mainly covered by a thick moss layer.
The forest is owned and managed by Gustafsborg Säteri AB (www.gustafsborg.se). The management turnover rate is 50 years, with an estimated growth of 34 m within 100 years. The site experienced storm damage in 1981, was clear-cut in 1982 and replanted in 1983 with 3300 trees per hectare. The forest was cleaned in 1998 and 2005 and thinned in 2009 and 2013.

Data for the 1961-1990 climatological normal from the close by SMHI station Ljungbyhed characterizes the climate as a Cfb-climate (after Köppen), i.e. humid temperate with mild summers and mild winters. Mean annual air temperature for Ljungbyhed is 7°C and mean annual precipitation sums up to 830 mm.
The measurements are carried out either on the 150 m high tower, at the earth surface, or in a soil pit and on a tree in one of the four continuous measurement points located around the tower. All measurements are carried out within a distance of about 200 m of the tower.
Hyltemossa Station has a main house and a workshop building. The main house is equipped with a classroom, kitchen, office, four bedrooms and and two bathrooms. It provides the possibility to hold small meetings or courses for up to 14 participants and an opportunity for overnight stay for up to ten persons.
