The network consists of 102 stations over the Lower Colorado River basin in central Texas. This data set covers the period from 1 May to 7 July 2003. The data are in columnar ASCII format. 2.0 INSTRUMENT DESCRIPTION 2.1 Instrumentation All the gauges have the same type of rain (Sutron tipping bucket), temperature, & humidity sensor. Most gauges have the same type of wind sensor (MetOne Sonic Windspeed & Direction). Not all gauges have every type of sensor. Many gauges do not have a wind sensor at all. I do not know the exact height of all the wind speed sensors. We attempt to install them at a consistent height but not all of them are. We do not have the height on record anywhere. The other sensors are not at a consistent height at all gauges either. 2.2 Station Locations Station location information can be found in the file gage_info_111703_a.xls included as part of this data set. 3.0 DATA COLLECTION AND PROCESSING UCAR/JOSS conducted no processing or quality control on these data. 4.0 DATA FORMAT AND FILE NAMING 4.1 Data Format These data are in columnar ASCII format.
