Processes and predictability associated with sub-seasonal rainfall variability in Brazil
Call closed on 4 December.
Submissions are sought on analysis of the processes and predictability of rainfall variability over Brazil in GCMs.
The ability of different modelling systems to represent the processes and drivers associated with sub-seasonal variations of rainfall over Brazil is of key interest to enable useful information to be gained from models on timescales from days to seasons to centuries. Sub-seasonal variations of rainfall in this region are known to be associated mainly with the Madden-Julian Oscillation (MJO) and other equatorial waves, modulated by the seasonal variations of the North and South American monsoons, the Atlantic ITCZ and the South Atlantic Convergence Zone. However, the ability of models to represent the processes linking these dynamical modes with variations in rainfall intensity and location has not been established. In addition, the role of local interactions and feedbacks through the land surface and vegetation cover in modulating the rainfall variability at intraseasonal timescales is not well understood.
Research is required into the representation of physical processes associated with rainfall patterns and intensities over Brazil in GCMs and how this affects a model’s ability to predict sub-seasonal variations.
Estimating methane fluxes through inverse modelling
Call closed on 15 November.
Submissions were sought on methane flux estimation using inverse modelling to better understand Brazil’s CH4 budget from available observations.
The research will seek to
- develop a high-resolution regional inverse modelling infra-structure centred on Brazil utilising available surface, airborne and satellite observations
- link with existing land-surface wetland modelling in CSSP-Brazil WP1 to gather together available a priori emission datasets into a cohesive and comprehensive database for use within the inversion system
- develop better understanding of the spatial and temporal distribution of CH4 fluxes across Brazil and surrounding areas with a special focus on understanding the anthropogenic and non-anthropogenic split of emissions, including sectors such as fossil fuel, agriculture, wetlands and fire.
The work should produce a critical assessment of how top-down and bottom-up modelling differ, and the relative strengths and weaknesses of each.
Meteorological driving data for offline land surface and impacts simulations
Call closed 15 November
Submissions are sought on developing methods and datasets of meteorological forcing data for land-surface model simulations to span historical and future periods.
The research will seek to develop methodology to extend historical datasets of meteorological driving data required for offline land-surface models. Specific focus will be on enabling the ability to extend existing offline ensembles (such as TRENDY) into the near future using initialised seasonal and decadal predictions. Anticipated outputs include:
- Tested and documented methodology for producing forcing data for land-surface models across observed and projected time periods
- Routinely produced forcing data to extend TRENDY simulations beyond present day using seasonal forecast, decadal forecast and centennial projection data.
