Sensors associated with new Whitewater EBBR installed May 1999. Note: On 24 Sep 2002, calibration changes were made, in the CR10X datalogger, for the 0-5 cm soil moisture measurements. These new calibrations are based on in situ determinations of soil moisture. Previous soil moisture measurements can be corrected; the equations for doing so are available from David Cook of ANL (see contact information below). Note that only the "30 minute" data (see below) are archived in the ABLE ASCII archive area at this time. Raw data files are however available for parsing out the 5 or 15 minute data if desired.
