13:30 - 14:30, Dec 21

Replaced Tsoil probe.

Lowered mast to clean krypton, clean solar, and clean radiometer

trailer test: brought probe back to trailer and did a visual check.

There was no sign on moisture in the connector. Did a simple ice

bath test and the probe was reading high. Will take back to Boulder.

   twh (3/1/11): high-rate data indicate kh2o cleaned at 14:03

                           high-rate u,w suggest mast down 13:59 - 14:05, but light winds make this ambiguous

          (3/3/11): high-rate pressure data confirm 13:59 - 14:05
