 Table Mountain Research
Table Mountain Facility Image

The Table Mountain Research Group comprises science and engineerign staff dedicated to the development and deployment of the atmospheric lidar and astronomy programs at the JPL Table Mountain Facility (TMF).

The atmospheric research areas are directed towards Sun-Earth System science, contributing measurements to the international atmospheric monitoring network NDACC that:

  • Provide observations to determine and understand the physical and chemical state of the atmosphere as they relate to ozone and climate change
  • Test and constrain models of stratospheric ozone depletion and recovery by providing key measurements of atmospheric trace species
  • Provide observations to determine and understand the processes thta control tropospheric ozone and climate
  • Provide observations to determine and understand the role of upper tropopsheric water vapor in the our changing climate
  • Provide observational evidence linking solar variability and atmospheric composition
  • Provide validation data for Earth Science satellites (such as Aura).

The lidar facilities include

  • Three lidars (Laser Remote Sensing) at TMF to measure vertical profiles of tropospheric ozone (2.5-25 km), stratospheric ozone (15-50 km), temperature (15-85 km), aerosols (15-40 km), and water vapor (3-20 km)
  • One lidar at Mauna Loa Observatory (Hawaii) to measure vertical profiles of stratospheric ozone (15-50 km), temperature (15-90 km) and aerosols (15-40 km)
  • ECC ozonesonde launch system for ballon-borne measurements of pressure, temperature and ozone (ground-35 km)
  • PTU radiosonde launch system for balloon-borne measurment of pressure, temperature and humidity (ground-35 km)
  • Two Frost-point Hygrometer systems for balloon-borne measurements of water vapor (ground-35 km)
  • Surface ozone photometer and surface meterology

Other atmospheric science facilities at TMF include:

  • A millimeter-wave radiometer (WVMS) operated by the Naval research Lab for the measurment of middle atmospheric water vapor
  • A GPS antenna/receiver for measurment of Integrated Precipitable Water (IPW)
  • A Fourier Transform Ultraviolet Spectrometer - Measures total column abundances of OH, NO3, CO2, BrO
  • Medium-resolution UV-visible Grating Spectrograph- used in lunar occultation mode to measure NO3

The astronomy facilities ( known as "Table Mountain Observatory") includes a 0.6 meter astronomical telescope that enables the following observations:

  • High precision astrometry of satellites, asteroids and for spacecraft navigation
  • Confirmation and follow-up observations of potentially hazardous asteroids and comets discovered by Near-Earth Object search programs
  • Physical characterization of asteroids, comets, and planetary satellites that are targets of spacecraft missions or Goldstone/Arecibo radar targets
  • Astronomical research such as volatile transport on Pluto and Triton and follow-up observations of asteroids and comets discovered by the WISE mission,
  • All-Sky Camera for detection of very bright meteors, i.e., bolides.
