MBLA  

Definition

  • The Multi-Beam Laser Altimeter (MBLA) for the Vegetation Canopy Lidar (VCL) mission, is a five-beam instrument with 25 m contiguous along track resolution. The five beams are in a circular configuration 8 km across and each beam traces a separate ground track spaced 2 km apart, eventually producing 2 km coverage between 67 degrees N and S, with orbit crossovers producing a denser grid away from the equator. Each laser beam operates at the 1064 nm fundamental wavelength of the neodymium-doped yttrium aluminum garnet (Nd:YAG) solid-state laser and are arranged in a pentagon inside a 20 mrad telescope circular field-of-view that is centered on nadir. Information on the MBLA instrument can be obtained from: "http://ltpwww.gsfc.nasa.gov/division/VCLhome/VCLInst.html" For more information on the VCL Mission, See: "http://essp.gsfc.nasa.gov/vcl/index.html" or "http://www.inform.umd.edu/Geography/vcl/" (en)
