Overview  
Title JAGUAR Data Assimilation System Whole neutral Atmosphere Reanalysis (JAWARA)
Sub-Title
Data Summary JAWARA is a long-term reanalysis dataset produced from the data assimilation system JAGUAR-DAS that covers the whole neutral atmosphere, from the surface up to the lower thermosphere (z = 0-115 km). The horizontal grid spacing is about 2.8 degrees, while the vertical spacing is about 1 km. JAGUAR-DAS uses 4D-LETKF and assimilates satellite observations of temperature from Aura MLS and TIMED SABER and radiances from DMSP SSMIS, as well as conventional operational meteorological observations. Temperature, three-dimensional winds, geopotential height, temperature tendency from diabatic heating, zonal and meridional forcings from gravity wave parameterization, and data assimilation increments are provided at pressure levels.
