Group: Summary

   Micro-climatic monitoring of air and ground was started in 1990 to evaluate 
   climatic controls on the present-day diurnal soil frost environment in the 
   Western Cape mountains of South Africa. To this effect two data logger 
   stations were established in the summit region of the Waaihoek mountains. Two 
   sites were established at Waaihoek Peak and Mount Superior, respectively.

   Waaihoek Peak - The Waaihoek Peak monitoring site is positioned on the 
   southeast extension of a small summit plateau at 1900m elevation where it 
   changes into a southeast trending ridge flanked by two small valleys. The 
   station stands on a 4 to 5 degree slope with an aspect of 140 degrees and is 
   underlain by steeply dipping quartzitic sandstone of the Peninsula Formation. 
   A shallow sandy soil here reaches a thickness of 0.35m and supports a sparse 
   vegetation cover of Restio (Cape reeds) species up to 0.2m high with a total 
   cover of around 30%. Initially both daily and hourly records were kept which 
   necessitated frequent visits to replace the data storage tapes. As from 
   29-11-1992 only daily records were kept, including maximum and minimum 
   temperature and 24 hour precipitation totals. Average daily soil moisture 
   levels were recorded only as the range between daily maximum and minium values 
   proved to be minimal.

   Mount Superior - Field observations established the presence of active soil 
   frost features near Mount Superior during December 1991. A second data logger 
   site was consequently established by 1-5-1993 to provide microclimatic data 
   from a site with a different substrate and currently active soil-frost 
   processes. The Mount Superior station is positioned 5km SSE of the Waaihoek 
   Peak site on a flat summit plateau of Cedarberg shale at 1860m elevation. The 
   surface cover is comprised of fractured bedrock and bare shallow soil with 
   tussocks of Restio spp. up to 0.5m high. Daily maximum and minimum temperature 
   were recorded for each sensor as well as daily average relative soil moisture 
   levels and daily precipitation totals.

   These data are presented on the CAPS Version 1.0 CD-ROM, June 1998.
