LBA Field Campaign
Model Initialization Data
LBA is an international field program designed to further understanding of the climatological, ecological, biogeochemical and hydrological processes in Amazonia, and the impact of land use change on these processes. The TRMM/LBA campaign took place in Brazil in the region 16S to 6 N and 76W to 49W (moving south to north and east to west) from November 1, 1998 through February 28, 1999.
This case study presents data from 1 Jan 1999 to 28 Feb 1999 and covers a region from 30S to 10N latitude and from 90W to 35W longitude.
6-hourly NCEP Reanalysis data are available here for certain pressure level, surface, and surface flux variables.
- Air temperature, Geopotential height, and U-wind and V-wind data are available at 10, 20, 30, 50, 70, 100, 150, 200, 250, 300, 400, 500, 600, 700, 850, 925, 1000 mb.
- Relative humidity and Specific humidity data are available at 300, 400, 500, 600, 700, 850, 925, 1000 mb.
- Vertical velocity data are available at 100, 150, 200, 250, 300, 400, 500, 600, 700, 850, 925, 1000 mb.
- Surface pressure, Sea-level pressure, Surface Temperature, Soil Temperature (0-10 cm), Soil Temperature (10-200 cm), Soil moisture (0-10 cm), and Soil Moisture(10-200 cm) data are available at a single level.
- A land/sea map and surface height map are also available.
