• On March 1 & 2, most of the state reported snow and a few hours of freezing rain.  In spite of the fact that the effect of this snow/ice event was much less severe than the January 30-31 storm, the wind obs at 60 sites had to be manually flagged for time periods ranging from 3 to 26 hours due to freezing rain coating the anemometers.  Temperatures in the state quickly recovered and on March 14, OKC set a record high temp for that date of 85 degrees.  The southeast part of the state experienced heavy rains on two occasions, with Idabel leading the pack at nearly 10" of rain during March.
  
  
• The Mesonet Technicians began Spring Pass 2002 in March.  During the month, they also resolved 75 trouble tickets!  In addition to the work detailed in this report, their work included scheduled replacements of 10m wind direction monitors (in the past four months, 100 have been changed out), and replacement of failed net radiometers, soil moisture sensors, ground heat flux plates and soil temp probes.  They also replaced 7 cup-type anemometers with starting threshold problems (likely caused by our three winter ice storms).  The initial installation of telnet power switches at base stations continued.
  
  
• The data collection software and hardware for the ARS Micronet was upgraded to match that used by the Mesonet (upgraded in the spring of 2001).  The new collection software is called LoggerNet.  Thanks to all who were involved in the successful completion of this upgrade.
