1 - Long Term Observation System
Start date or starting event: full duration of project
Long term observation systems and data integration and consolidation
1.1 To observe the fluxes of carbon, water and energy from representative
land use/cover types of key regions in western and southern Africa by
1.2 To analyse and to partition the net-fluxes measured by eddy-covariance
and to understand the relationship between the components (Gross
Primary Production and Respiration) and climate for different vegetation
and land use types in different climates.
1.3 To provide the basic data for process understanding analysis (WP2)
and parameterization of models for up-scaling of carbon fluxes to the
regional and continental scale (WP3).
|Description of work |
Task 1.1 Establishment of a pilot eddy covariance flux network in
Africa by identifying established sites and setting up few additional
flux towers. Measurements will be harmonized in terms of methodologies,
protocols of measurements, and data sharing. This task includes also
the assimilation of data from former projects.
Task 1.2 Data consolidation will comprise quality control, flux
partition and gap-filling of the eddy data, standardization of the
others point data (TEMS) and reprojection, mosaicing and correction
of the remotely sensed products.
Task 1.3 Design an optimal monitoring system network and the
identification of its components, by the estimate of the representativeness
of flux towers.
1.1 Fully operational eddy covariance flux network within the
defined key regions (Month 6).
1.2 Sets of continuous flux data of carbon, water energy and
the associated meteorological and ecological variables at the core
sites (Month 6-36).
1.3 Maps and remotely sensed products at continental scale,
harmonized and georeferenced (Month 12).
1.4 A public-domain database of carbon-cycle related observations
in Africa (Month 12).
1.5 Standardized version of site ancillary data available (soils,
vegetation etc) (Month 18).
1.6 Integrated observation product outputs for Africa, such as
spatial databases of calculated carbon fluxes and stocks (Month 36).
1.7 Identification of an optimal monitoring system network for
the Sub-Saharan Africa context (Month 36).
|Milestones and expected result|
1.1 Collation of all readily-accessible and quality-controlled
existing site data on specified carbon cycle variables. Analysis of this
dataset will identify the thematic and geographical areas where the
information is weak, and trigger a gap-filling exercise where feasible
1.2 Publication of Africa-wide integrated spatial data products
for the key components of the carbon cycle: ecosystem and anthropogenic
stocks and fluxes (Month 18).
1.3 Building-up of correlation curves between biomass and canopy
cover for each life form and ecological zone (Month 24).
1.4 Design an optimal monitoring system network and the
identification of its components (Month 36).
