The light is then sent into the atmosphere via a scanning mirror. The detectors are photomultiplier tubes which enhance the weak backscatter signal from the aerosols and molecules. All of this equipment is located inside of one environmentally controlled trailer. This allows the SRL to be readily transportable. Two of these are data files, one each for aerosols and the other for water vapor.
Image files are time series representations of data files.
The format as indicated by the file name is in ascii. 6.0830e-002 Each of these data files are made up of all of the profiles which were captured during that observation period. These correspond to the number of layers into which the vertical structure is stratified. Data follows in this set for 160 lines and are organized into six columns. 1 - bin number and has no header.
