NCAR/ATD/RTF Preliminary Home Page for RIME

This is a preliminary home page for NCAR / ATD / RTF operations for the proposed Ross Island Meteorology Experiment, RIME.

NCAR has extensive experience with our Integrated Sounding System (ISS) facilities for making meteorological measurements of the lower atmosphere. A specialized version of these facilities, with a preliminary name of HISS (High latitude Integrated Sounding System) has been proposed for polar experiments such as RIME.

The components of HISS are still being considered, however would generally follow the components of our ISS and include:

• A small VHF wind profiler radar operating at about 50 MHz. A candidate for this system is the ATRAD BLTR (Boundary layer Lower Troposphere Radar). For photograph of this system click here. It is expected that this system would provide wind measurements from about 300 meters up to about 4 - 6 km above the radar every few minutes. This radar would replace the 915 MHz profiler which would probably not perform well in Antarctica.
• A sodar to provide wind measurements from about 30 meters up to 300 - 500 meters. A candidate sodar would be a larger version of our existing Metek DSDPA.90-24 sodar. For a photograph of our current sodar click here.
• A computer workstation to integrate measurements from these systems and other instruments that may be added to the facility.
• Surface meteorology instruments and radiosondes may be added depending on the application.
