RAMS  

Definition

  • A single Radiation Measurement System (RAMS) consists of a variety of broadband and spectral radiometers developed and maintained by the Atmospheric Research Laboratory at the Scripps Institution of Oceanography, University of California, San Diego. A RAMS is mounted on both the zenith and nadir positions on each aircraft for the purpose of measuring both downwelling and upwelling fluxes. All of the instruments composing a RAMS have hemispheric fields-of-view and are located in positions on each aircraft which minimize obstructions from their view (i.e., tail fins, radio antennas, landing gear, etc.). Because both downwelling and upwelling fluxes are measured on a single plane, the net flux at a given altitude is easily inferred by a pair of RAMS. The RAMS Instrument package has been part of the ARM-UAV program and has flown on and been located at surface stations during the ARESE, S96, F96 and F97 flight series.
