LBA Data Set Released from the Physical Climate Science Research Theme

The ORNL DAAC announces the release of a data set from the Physical Climate (PC-06) Science theme of LBA.

• LBA-HMET PC-06 ECMWF Modeled Precipitation and Surface Flux, Rondonia, Brazil: 1999. Data set prepared by A.K. Betts and C. Jakob. This data set provides the mean diurnal cycle of precipitation, near-surface thermodynamics, and surface fluxes generated from short-term forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) model. The ECMWF model was run for two LBA campaigns conducted in Rondonia, Brazil during January and February of 1999:  Wet Season Atmospheric Mesoscale Campaign (WETAMC) and the Tropical Rainfall measuring Mission (TRMM).

LBA was an international research initiative under the leadership of Brazil. The project focused on the climatological, ecological, biogeochemical, and hydrological functions of Amazonia; the impact of land use change on these functions; and the interactions between Amazonia and the Earth system. The LBA-ECO component, which was funded by NASA, focused on the question: "How do tropical forest conversion, regrowth, and selective logging influence carbon storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable land use in Amazonia? "

See the LBA Project page for further information about the study and to access associated data and documentation maintained by the ORNL DAAC.

The ORNL DAAC is a NASA-funded data center archiving and distributing terrestrial ecology and biogeochemical dynamics data.
