- It is a major challenge in modem science to decrease the uncertainty in predictions of global climate change. One of the largest uncertainties in present-day global climate models resides with the understanding of processes in the soil-vegetation-atmosphe

Tidskriftsartikel (refereegranskat)abstract
- Radiosonde profiles in the atmospheric boundary layer (ABL) with other supporting measurements obtained during NOPEX Second Concentrated Field Effort over a complex area in Sweden were analyzed to determine regional momentum fluxes. Two methods were explo

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Knowledge of regional roughness parameters is needed for remote sensing and large-scale modelling purposes. The presently available estimates of the most problematic parameter, namely the regional thermal roughness length (z(0t)), have mostly been determi

-
Tidskriftsartikel (refereegranskat)abstract
- Long term measurements (June 1994 to December 1996) of evaporation were made in a boreal forest in central Sweden. Fluxes were measured continuously with eddy-correlation systems from a 100 m tower. Surface conductance and potential evaporation were estim

Tidskriftsartikel (refereegranskat)abstract
- Calculation of fluxes from profile measurements above forest stands have for some time been considered unfeasible and profiles have primarily been used to only characterise the lowest part of the planetary boundary layer. Extension of traditional theory t

Thermal roughness length of a boreal forest

Ingår i: AGRICULTURAL AND FOREST METEOROLOGY. - : ELSEVIER SCIENCE BV. - 0168-1923. ; 98-9, s. 659-670
-
Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to determine the roughness length for temperature (z(ot)), which has rarely been done for forests. The analysis was based on measurements of profiles of wind speed, air temperature, and surface radiation temperature in a forest a
