1. Baseline Map of Carbon Emissions from Deforestation in Tropical Regions
Policies to reduce emissions from deforestation would benefit from clearly derived, spatially explicit, statistically bounded estimates of carbon emissions. Existing efforts derive carbon impacts of land-use change using broad assumptions, unreliable data, or both. We improve on this approach using satellite observations of gross forest cover loss and a map of forest carbon stocks to estimate gross carbon emissions across tropical regions between 2000 and 2005 as 0.81 petagram of carbon per year, with a 90% prediction interval of 0.57 to 1.22 petagrams of carbon per year. This estimate is 25 to 50% of recently published estimates. By systematically matching areas of forest loss with their carbon stocks before clearing, these results serve as a more accurate benchmark for monitoring global progress on reducing emissions from deforestation.

2. Climate and vegetation controls on the surface water balance: Synthesis of evapotranspiration measured across a global network of flux towers
Key Points
Global FLUXNET data support Budyko hypothesis of surface water balance controls
Climate type, vegetation type exert additional control on evapotranspiration
Grasslands exhibit higher evaporative index than forests

3. Swiss prealpine Rietholzbach research catchment and lysimeter: 32 year time series and 2003 drought event
Key Points
Unique hydroclimatological data set including multidecadal lysimeter record
Evapotranspiration as major and underestimated driver of 2003 European drought
Precipitation deficits in spring 2003 play a minor role for drought development
