SGP/TWR/C1 - West-side 25m Temp/RH Calibration
DataStreams:sgp1twr25mC1.a0, sgp1440twr25mC1.a0, sgp30twr25mC1.a1
Description:
On Feb 7 a communication problem was discovered for the 25 m level system. In 
troubleshooting the system, the power to the dataloggers was turned off. This caused the programs 
from the storage modules to automatically load into the datalogger.  These programs 
contained the wrong calibration for the T/RH sensors.  

Only the 25m temperature calibrations were significantly affected. The error in the 60m 
temperature data is only +0.2 degrees C at maximum.
