Arctic Biosphere Atmosphere Coupling at Multiple Scales: Work-Packages

The project has eight work-packages. Each work-package has a post-doctoral research associate (PDRA), a leader and associated investigators (identified by initials). A half-time project manager is in charge of WP8. WPs 1-3 focus on detailed fine scale measurements (~1 m resolution) and experiments based at, around and between each of the four tower locations (Fig. 4). Measurements at the field scale (~100 m resolution) are derived from the four flux towers, WP4. Landscape measurements are generated by the aircraft (WP5) and satellite images (WP6). The modelling, WP 7, links across scales, integrating data from WPs 1-7, and providing feedback to the measurement components. WP8 governs management, dissemination and training, controlling and monitoring the provision and exchange of deliverables. For each WP below we list the deliverables (datasets and associated papers) and the tasks required to achieve them. The critical deliverables are (1) soil, vegetation and topographic survey data from WP1, 2, and 5 to WP6 for geostatistical analyses, and (2) spatial data from WP6 and time series of flux data (from WP3, 4 and 5) to WP7 for integration and assimilation with models.


The figure indicates the links among the project components. From the surveys by WPs 1,2,5 and 6, maps of each study region will be constructed. These maps will be used to test H3 and to drive the models in spatial modes. Flux data from chambers will be scaled by simple models to compare to tower data. Tower data will be scaled by SPA and JULES to compare with aircraft data. Experimental outputs from WPs 1 and 2 will be verified and assimilated into the modelled C budgets generated by SPA/DALEC.
