CLIMEX Climate Change Experiment: Final report on Phase I the first year of treatment May 1994 - Desember 1994
(NIVA-rapport;3392, Research report, 1995)Catchment ecosystems are expected to show a cascade of responses to increased CO2 and temperature. The first expected step was observed in the first year of treatment increased CO2 changed rates of photosynthesis and ... -
CLIMEX Climate Change Experiment: Progress report December 1992 - June 1993
(NIVA-rapport;3389, Research report, 1995)This report describes the technical installations at Risdalsheia and the establishment at permanent plots for scientific studies of vegetation and soils at the 5 experimental catchments. -
CLIMEX Climate Change Experiment: Progress report July 1993 - December 1993
(NIVA-rapport;3390, Research report, 1995)This report describes data obtained during the pre-treatment period at the Risdalsheia site. Results from laboratory experiments with plants and soils are also reported. -
CLIMEX Project: Climate data for first year of treatment April 1994 - March 1995
(NIVA-rapport;3339, Research report, 1995)Climate change treatment began in April 1994 at the 2 experimental catchments. At KIM CO2 is increased (to 560 ppm) and air is heated (by 3¨ C in summer and 5¨ C in winter). At EGIL soil is heated. Except for an initial ... -
Climex project: Data report for June 1994 - May 1999
(NIVA-rapport;4157, Research report, 1999)CLIMEX project was conducted from May 1994 to June 1998 and involved whole ecosystem manipulation of temperature and CO2 at the catchment scale. Measurements of precipitation and runoff continued for one-year post-treatment ... -
CLIMEX project: Report on the second year of treatment May 1995 - December 1995
(NIVA-rapport;3526, Research report, 1996)CLIMEX is a integrated, whole-ecosystem research project studying the response of entire forested catchments to increased CO2 and temperature. These whole-catchment manipulation experiments are designed to allow quantification ... -

CLIMEX project: Response of runoff chemistry after 2 years of elevated CO2 and temperature
(NIVA-rapport;3542, Research report, 1996)CLIMEX is an integrated, whole-ecosystem research project studying the response of entire forested catchments to increased CO2 and temperature. KIM catchment receives clean rain, elevated CO2 and elevated air temperature. ... -
Dynamic modelling of soil water acidification: display and presentation of results for policy purposes
(NIVA-rapport;4733, Research report, 2003)Dynamic models for soil and water acidification and recovery are becoming increasingly important tools in determining policy for future emissions of air pollutants in Europe. Dynamic models represent the next step in ... -
