Description: Das Projekt "WINTEX: Wechselwirkungen Landoberflaeche/Atmosphaere in einer winterlichen borealen Landschaft - Planung einer NOPEX-Winter-CFE" wird vom Umweltbundesamt gefördert und von Eidgenössische Technische Hochschule Zürich (ETHZ), Institut für Terrestrische Ökologie ITOE durchgeführt. The Continuous Climate Monitoring (CCM) programme consists of two main field micro-meteorological and actinometric stations together with four research catchments. Two CFEs have been carried out in the spring and summers of 1994 and 1995. Since the main objective of NOPEX is to study the annual and daily cycles of the regional land-surface budgets of energy, water, and CO2, plans have been to perform a third CFE during winter conditions. A full-scale such experiment will be very resourcedemanding and must be very carefully planned in order to minimise risks with a failure. It is the objective of this proposal to perform this planning. Measurable objectives is to provide this planning through the following activities: (1) Use of mesoscale atmospheric models, tested over the NOPEX area with data from the CFE1 and CFE2, to test various hypotheses for processes which are likely to be important in winter conditions and to perfom sensitivity analyses of these models; (2) Use of hydrological models including dynamics of snow and frozen soils. Such models will be tested against measurements from various types of land surfaces. Remote-sensing data coupled with GIS techniques will be used to make modelling results available as lower boundary conditions in the meso-scale atmospheric modelling; (3) Evaluate remote-sensing techniques to test and develop algorithms describing facets of the NOPEX winter-time landscape. The remote-sensing data will be carefully integrated with the requirements from the modelling groups in the project; (4) Perform a limited pilot experiment to test measurement equipment in order to earn practical experience in the special climatic problems to be encountered during winter conditions (freezing temperatures, long nights, low solar angles, snow fall blowing past precipitation gauges etc...). Such tests will specifically be made within the NOPEX CCM (Continuous Climate Monitoring) programme (running since May 1994) to improve the chances for this to deliver unbroken data series also during harsh as well as rapidly changing winter conditions and to guarantee availability of data from climatic events that occur seldom but which may have a large importance for the budgets of water, energy and carbon.
