ACTRIS-2 provides access support to the Hyltemossa site for external (non-Swedish) researchers or research teams as part of the ACTRIS-2 transnational access (TNA) programme.
Location: 56° 5' 52" N, 13°25' 8" E, 115 m asl (Southern Sweden, 18.5 km ENE of current ACTRIS site Vavihill)
Nearest small town: Perstorp; Municipality: Klippan; Province: Skåne; Country: Sweden
The site was established in 2014 (ICOS).
Hyltemossa is an ICOS combined atmosphere and ecosystem station, with ICOS activities operated by the group of Prof Janne Rinne at Lund University.
ACTRIS activities at Hyltemossa is operated by Lund University.
Description of the infra-structure
The groups involved in ACTRIS at Lund University are currently moving all aerosol research activities from our current ACTRIS site Vavihill to the newly established ICOS-Sweden site at Hyltemossa in southern Sweden. The co-location of ICOS and ACTRIS observational capabilities at Hyltemossa offers a comprehensive research infrastructure that is essential for studying the multiple and tightly interlinked processes that control the land ecosystem – atmosphere – climate system. The site is unique in the sense that it is situated in a highly productive and well-managed 35 years old Norway spruce forest (Picea abies), representing typical Northern European forest management conditions aiming mainly to optimize commercial yields. The air masses and pollution levels at Hyltemossa are very similar to those at the present ACTRIS site Vavihill.
A 150 m high tower was erected in March 2014 at the Hyltemossa forest site, and installation of ICOS instrumentation and sensors are fully operational. ICOS measurements at the Hyltemossa tall tower include profiles of CO2, CH4, CO and H2O, radiation balance, eddy covariance fluxes of CO2, H2O, heat and momentum and various soil properties.
For ACTRIS, a 30 m high tower was erected in August 2016 at the Hyltemossa site, in close vicinity to the laboratory building. This tower supports the aerosol inlet that samples air from well above the forest canopy.
The aerosol instrumentation for continuous measurements are: PM10/PM2.5, aerosol size distributions (AIS, DMPS, APS), absorption (7-wl Aethalometer, MAAP) and scattering (3-wl nephelometer), cloud activation (CCNC), aerosol chemical composition (Aerodyne ToF-ACSM) and OC/EC. Gas measurements include NO/NO2 and O3. OC/EC filter samples are also analyzed for organic tracers and 14C for organic aerosol source apportionment. Campaign-wise measurements of aerosol chemical composition (Aerodyne HR-ToF-AMS with a Soot Photometer), a DMT SP2, VOC (PTR-ToF-MS), Aerosol particle density (DMA-APM), and hygroscopicity (H-TDMA).
